Question about Polaroid FLM-3734B 37 in. LCD HDTV
I've had the tv about a year. Yesterday the blue light would come on, but there was no picture. After turning the power off a couple of times it came on. Today it won't come on at all. Please help.
First, I am no tech, this is at your own risk! I have a flm-373b which is out of warranty 15mths. A nice paper weight. Plug it in, blue light, no picture or audio. So I got the service manual and started taking it apart. Pulled out the so called control box and at the top is what appears to be some sort of power inverter board. I looked closely and saw that there were 2 capacitors that looked damaged. One was bulged and the other looked like it had popped. They were side by side, green and marked 1000Uf 10v. I took the board to work with me and unsoldered the capacitors and very carefully replaced them with 1000Uf 16v caps. This was just a crazy chance. When I got home I put everything back together, ran 2 extension cords to the back porch and plugged it in. The tv came on faster than when it was brand new. Now I have waited 3 weeks to post this, just in case my house burned down, but the tv is still working great. Again this is at your own risk. Polaroid is not helpful and they want you to spend more money to correct their problem which will probably not correct anything. I really do wish you luck with this or with putting up with polaroids BS.

Yesterday I discovered that I too had this problem with my Polaroid TV. I found this forum, and the person who suggested to replace the cap's was correct, at least in our case. We took our 2 year old TV apart found the control board, which for those that don't know, when you take the back off, locate the plug wires from where they come into the back of the TV follow them up and it will end in the control board. Any way after looking at it we discovered that 2 of the cap's were bulging. This was not just take a quick look, one of them was so slight that it wasn't even really apparent until we scrutinized each one. The two that went out on ours were the 2 located in the upper left corner of the board, they are 1000 CU 10 V cap's. We took the board into our local electrician, 1 hour and $17.00 and the TV is working again. I would like to that the person who suggested this as it worked for us.

Polaroid HD TV, 37' LCD (FLM-3732 which is the same as FLM-373b but hase more features) - when cold must unplug and re-plug AC, power on - no logo, just some sound snaps. Eventually after about 10 tries it comes up with a picture but the sound has loud hum which gets quieter and then ok after about 15 seconds - then all fine. While hot can turn it off and on fine, just a cold start up problem.
I replaced the 2 capacitors and it's like new again - cost $3.00 Even though the caps did not show any sign of failure - no bloating or constipation:)
I have been servicing computers for over 43 years and you can guess my level of expertise:)
If you don't want to do the soldering etc, take these details to a TV repair and have them replace the capacitors, should be a lot less than the board at $600.
See the following link for pictures.

If you are having a blue light without a picture you need to remove your control board and check for two capacitors that are marked 1000uf10v. as with my experience with these tvs I believe the capacitors are too small to handle the work load. I replace them with 1000uf35v from radioshack these are about $2.00 each. remove the bad ones and solder the new ones into the control board and this should fix your problem. the capacitors are on the uper left hand side of the board, next to each other. they can be green or black they are the only ones that are 1000uf10v on the board . hope this helps.

Hello every one I have emailed a letter I copied and pasted all the complaints here and sent it to Petters Group LLC. This is the investment Company that owns Polaroid. I felt that most likley they were not aware of any problem with one of their brands. I may get somewhere or I may not. This is not just one model of Polaroid 37" LCD TV. They all share the same Control Box they just change a certain number in the product code depending on size of screen. Here is a copy of the letter I emailed them. One person is not going to change the situation so if everyone here emails Petters Group LLC. about the problem they just might do something. Their email address is firstname.lastname@example.org.
Here is the copy of the letter. Good luck to all.
Dear Petters Group,
It appears that there is a problem with your Polaroid LCD TV brand.
Included is testimonials from a small fraction of customers that I found on a
web site that have bought your Polaroid brand 37" LCD TV.
I have the same problem with my TV that these poor people have. I bought my TV
in February 2007. Now in June of 2008, One year and four months later my TV has
started to not work correctly. This is what happens, I turn the TV on and the
indicator light changes from red to blue showing the TV is on but the screen
still looks like it did when the TV was off. Now when you push the button on the
remote or on the TV itself to turn it off it will not turn off. You have to
unplug the TV and plug it back in and then turn it on again and so far this has
been working, But if you read these testimonials below you will see that in a
short time the TV will not work at all.
The problem lies in the Control Box and this cost a whopping $600+ for just the
part and this is not including the cost of a repair person. This is a good amount of money to spend on a TV that is
only a little over a year old.
I as well as the people who have made the comments below have all shelled out at
least $800.00 to $1,000.00 if not slightly more to Buy Polaroid TV's. I was sure
that when I bought mine that the Polaroid name was one of quality and I am sure
that these other people had thought the same thing. I believe there is a defect
in the Control Box and that there should be a recall or refund on these units. I
have not contacted customer service because as you will read it appears to go no
Like one person here who said that Polaroids customer service told them
"Thousands of these units have been sold so a few hundred having the same
problem 12 to 16 months after being bought does not warrant a recall" I beg to
Does the name Polaroid mean quality or has it gone to the way side and been
replaced by the top dollar and junk.
I would like to think that you would care just a little about the customers that have long made your brands what they are today.

You can call the horrible thieves at Polaroid and ask them where to get the control box. They'll give you an 800 # and also give you a number to call to get it installed - ha - which in my area was Sears by the way. Of course when you complain about the TV and all of us having the same problem, they start telling you how many TV's they've sold and what a small percentage of us have problems. They're liars and thieves - spread the word.

Yep Yep, same problem..... I took my 37 inch apart, found the 2 caps that were mentioned in the forum. Although I had to look very very close to see that the tops of the cap. were slitly damaged I figured this was the problem..... It was! I went to Radio Shack bought the 1000uf 35v cap. and took the board out and replaced to 2 1000uf 10v. I put all back together and it seems to be working just fine. Thank to all the folks that posted the solution. I was about to toss the tv away after paying just over a 1000.00 for it.

Ill buy it from you. name your price

I've been reading this board for a while and wanted to pass along some info. Appears Polaroid is providing parts for sale. From what I am seeing, they have control boxes around $100. Sounds like a smokin' deal compared to some of the other places that are selling them.
Also, I think they are offering In-Home service at a flat-rate price - something like $225...

I have the same problem with the 37"/flm-373BPolaroid LCD the blue light comes on but no picture. when I turn on the TV the blue light comes on, flickers and stays blue but not as bright.... still no picture! can anyone help? thank you, rinsight2

I have had my 37" poloroid tv for just over 14 months and it will no longer turn on. The blue light comes on, but no picture. was told it was control panel and will cost over $600.00 to fix. please help!
Posted on Nov 02, 2008
Replacing the two capacitors. It works. I used two 1000 uf 35V capacitors from Radio Shack. Cost $22.00 including soldering iron. The capacitors on my control board were black.
Posted on Nov 02, 2008
Same Problem...turn my flm-37 on and a blue light only would come on, so i would unplug it and plug it back in. usually it would turn on and make an awful humming noise for a while like i started up a small lawnmower. now the tv wont do anything. i bought this at wal mart 18 months ago and opted to get the 2 year extended warranty. they are sending me a casket this week, hopefully this works...poloroid sucks.
Posted on Nov 01, 2008
I had the same problem. The capacitors didn't even look damaged, but I switched them out anyway and it worked! Thanks to whoever posted this solution.

Well, bet you can't guess what happen to my flm373B Polaroid tv yesterday.... same story as all the rest, got 15 months out of it.. but thanks to the folks that have posted the solutions for this problem, I took the back plate off of it, found the control box, and the same two compasitors had dome heads on them, unhook the 3 cables, and then took out the 4 screws, and made a few phone calls to local tv repair shops, One would not do it, one wanted 125.00, and the third, was 29.00...yey,,,yey,,, replaced the defective compassitors, and labor, in a hour, Came back and picked it up, took it home, put it back together,,, 10 minutes, and did a reset, and works better than before, Now I did go with the 16v caps, they are rated a little higher for heat, that should prevent the problem in the future, Now what I would like all of you to do that have or are having the problem with these Tv's, is send a email to the headquaters of where ever you bought the tv, and to Polaroid.. ask the company you bought it from to talk to there supplier about the defect in this tv, this could be a case where Polaroid got some bad Compasitors, or just were to cheap to use the a better one. Call it a design defect with a potential fire hazzard. If anyone is doing a class action, I would be happy to join, because with this many tv's having the SAME problem, it is a result of the same part failing.. I am sure that Polaroid, could work out a fix with the SEARS repair service to fix these for 25.00 or less. If you read the post about the cost of the control box, and the core fee, you can see that the Company is making about 300 dollars proffit on every tv they fix.. and then if they replace the copassitors on the core for 5 dollars, they make another 295.00 on the next person that has the problem,,, CUSTOMER SERVICE ONCE WAS A STANDARD, NOW YOU MUST DEMAND IT... Thanks again for the help, Ron

I tried changing the caps, actually had an Engineer do it for me and sadly it did not work for mine.
My symptoms were a shrill almost tone like sound coming from the TV when i turned it on.Gradually after 3-5 minutes the tone would go away. Over a month or so it got worse and then yesterday right in the middle of NFL football it went out.
I could unplug it and plug it back in and the red light would come on but when I hit the power button I would get a blue light for 2 seconds and then it would cut out.
I had the engineer put in 25v's to replaces the 10v's (which did have swelling).
It's now at the TV repair shop, the guy said he thought he could fix it for $50 bucks but I'm not holding my breath.
The TV is out of warranty so I guess I'm out of luck. I have had it nearly 2 years.
Next time I'll spring for the extra cash and get a reputable HDTV brand with an extended warranty.
POLAROID will never get another cent from me for any product they make.

Well guys - you have my sympathy. It is bad. I fought with Polaroid for months over my 16 mth old 37" TV doing the same thing. I finally gave up, bought a 42" Vizio and decided what have I got to lose now. I boxed up the Polaroid, costs me $60 plus shipping costs and I shipped it to their customer service dept in CA with $800 insured value. I included a letter that said "fix it or keep it - I really don't care " and I copied the letter to every consumer group and agency I could think of to send it to. Polaroid went nuts. I got about 3 calls from Polaroid and they were mad asking why did I send it to them and what did I expect from them. I repeated what I said in my letter - a broken 16 mth old TV sitting in my house wasn't doing me any good and if anyone was going to throw it away, it should be Polaroid. I just told them I expected some inquiries on my letters but I would hold off until they (Polaroid) decided what they were going to do. Several weeks later I got my repaired TV FedEx'd to me. Who knows how long it will work but at least something was done.
You just have to resign yourself that you really have no alternative and hope that you get someone at Polaroid that decides to do the right thing. I can assure you, they are few and far between. CAUTION: don't buy any Polaroid stock.

I too am having the same issue. I am working on contacting a layer to file a class action suit.
Please contact me with your name and email address if you would like to be involved in this suit.

It seems that the manufacturer of the Polaroid FLM-373b HDTV either
used the wrong parts or there is a design problem. I found someone on
the internet who said they replaced two capacitors on the power board
and it started working just fine (see solution #8 above). I took the power board out of mine
and sure enough the two caps with the 10v markings were swelled. I
replaced them with two 25v caps and it is working just fine. All the
other caps on the power board were 16v and above. So, I would assume
they were shipped the wrong parts or they just put the wrong caps in to
begin with. If you want to send me your power board I will fix it for
$50.00 plus shipping.

I also dished out a grand for their flm-373B and got the shaft cause my warranty expired 3 months after my warranty date. Luckily I found a brand new control box on EBAY for a cheap price and havent had I problem since and that was 3 months ago.
There's a Polaroid Assembly Control Box #909-KEO-GF371XAH that was posted on ebay a couple days ago. It might be the way some might have to go since Polaroid's not stepping up and taking care of their customers!!!!!!

Getting my 3rd control box today, tech is on his way out to put it in. called polaroid andtalked to manager he told me that if this one doesn't work then they will ship out new t.v. 2day express. good thing is they don't make 37" inch t.v. anymore so suprise suprise i get a 40" with new warranty!!! trust me don't give up keep bothering them call them every other day until they do something about it don't let them smooth talk you and also do not talk to customer support ask for manager you get better results. also mention that you went online and seen that there are about 100 different people that have the same problem with same style t.v. it makes them feel like **** and they also don't want people to spread the word that there t.v.s **** so believe it or not if you stay on them and raise your voice they will listen and fix t.v. or replace it i gaurantee that!

I just wanted to update what happened to me. I called polorid and they agreed to send out a replacement part on back order. Like previously indicated I was to call an 800 number to schedule installation. Sounded like a run around but it worked ...well sort of. Like previously stated the part shipped didn't work and the tech got on the phone with them. Just mention to them is smells like something is burning and they offered to end out a new TV. After waiting they sent a new tv with new warranty and sent a box for me to ship the old one which I did. No problems so far.... fingers are crossed!

I posted in this forum about the same thing. My tv was 2 weeks out of warranty. Polaroid said there was a 45 day grace period. So they sent a new control box and had a repair tech come out. The first one didn't work but they sent out a second box and I put it in myself. Complain and ask for a manager if you have to.

Same problem I have the flm-3732 and you do not have to replace the whole control box. The power supply board inside the control box is the problem. The power supply is made by Element Electronics and also used in Element lcd tvs. My power supply board # is mlt070a and it is $135. on ebay or on shopjimmy.com it is very easy to replace take out control box unscrew the cover (3 screws) then 4 screws hold in the power supply board and a couple of connectors will need to be unplugged. If you are going to try this be very careful when removing the control box there's a connector coming out of the box that plugs into the top underneath the box not too much slack so don't rip it. It is very easy to do even if you don't know what you're doing it should only take about a half hour. Please remember my tv is the flm-3732 so take out your board first and make sure yours is the same example: I know the flm-3701 board isn't even close to the board in my flm-3732 so not all 37" have the same parts. Good luck

I have found a guy who fixes this specific problem at www.mikecampagna.com/Polaroid
Posted on Jul 03, 2008
It worked. I replaced the two bad capcitors on the control board and presto. Thank you for solving this. I just about threw away my expensive HDTV, but for only 20 bucks it now works. I hope we can let more people know.

I have the same problem, very unreliable, just tried solution posted on this board and it worked. Turn on - while LED Bliinks push the channel button - also tap back a few times not too hard not too soft - possible problem(s) here, as suggested on tyhis board, capacitors (sic?), poor soldering connection, (In which case tapping might make it worse, but if you have no pic, nothing lost nothing gained), good luck, repair work suggested at about 200 bucks on this board.
Posted on Mar 02, 2008
Here's the fix:
I had the same problem with mine. Replaced the capacitors and now it works. When you open the back of the tv up, the problem is with the 2 capacitors on the upper left of the top card. Mine didn't look damaged except for a very, very slight bulge on the top. If you've never soldered anything, you might want to take it to someone who has, otherwise, it's a pretty simple fix. I was surprised I could do it so easily.
If the warranty is still good, make Polaroid replace it. They make shoddy products and should pay for it. And never buy another Polaroid again.
