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.
My friend didn't have his tv on a surge protecter, and it fried something on the tv. He took it in, and they told him it would be around $800.00 to fix it. The tv use to turn on but no picture, now it doesn't turn on at all, I haven't played with it to much. People have said it could be a fuse, or the video card. If any body has any troubleshooting help that I could try, I would appreciate it. This is for a Polaroid 373B 37" lcd tv
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.

Hey guys, I read the solution about replacing the 10v 1000muf caps in the power supply module. I was ready to throw the set out. I tore apart an old old old Jerrold 700 converter and found a couple of caps that were 1000muf. One was 26v and the other was 52v. Anyway, the set works great now and I now have a 37" LCD in my shop to watch the Leafs!!!!
Thanks for the advice.

Hello and Thanks for e-mailing. Actually here is what I have done, please read this and call me directly if you wish to chat about it. I am currently working with corporate side by side on my problem so I think I can help.
A large number of tv's that are aprox. 2-3 years old had faulty control boxes and other manufac. errors when created. Once Polaroid found out about these numerous problems they began figuring out a solution. Well, due to the fact that the control box only accounts for some of these problems it may or may not work to do this fix.
Polaroid offers an out of warrenty repair program now for $210 dollars. They send out the control box and a tech. The tech. is from a 3rd party organization and will need to work with you independantly to set up an appointment. This may fix your TV however I found out after I had him come out that this was only 1' of my problems!
I guess the part that went out in my TV in addition to the control box was the Ybus - board?! This part cost $120 and Polaroid said I had to call their distributor to find the part. They said they cannot find the part so I would have been out the TV.
So here is what I am currently doing and had to do in order to get this far.
1) 10 calls into CS with numerous different responses and personalities. It has taken numerous hours of my time to get here.
2) Polaroid used to offer the $310 replacement TV offer, you send back your TV, pay the shipping of $100 aprox. from UPS and pay the $310 and they will send you another. However, they refuse to do this anymore, I had to battle them for about a month and now I await my exchange.
3) I am working drectly with corporate and they were able to aid me, however for some of this you still have to deal with CS and they are awful.
** Here is what I reccomend;
1. Do not unplug the Tv from the back of the Tv. My TV worked fine even though the noise came on when I turned it on until I unplugged the back cord. Than the screen would pop off so perhaps leave it plugged in.
2. Contact CS and tell them that you have this problem and that you have done your research and that you would be willing to have a tech. come out for the $210 and the new control box. However DE-mand that they refund yor money if that part does not work. They will decline but tell them you will report them to the BBB if they do not comply.
3. Never buy their products again, to answer your question I have NOT tried this fix for $20-30 but would have if corporate would not have aided me. However this fix only fixes the control box problem so if you have another problem you are still only half way....My wife and I have had many ulcers over this and I wish you the best in this. Feel free to request a call, I do not want to add my cell here, I guess.

Hello jrcgoat, First check your audio settings by going to the TV menu, making sure mute is off, and audio is set to mid range. Once that is done, if possible use the other HDMI port. Now if the other port is not functioning then the problem is in the circuits after the HDMI buss, however if the other port funcions the the problem is in the actual HDMI interface. Usually the port and the support circuits are on the same board, if they are for simplicity I would say to replace the board. However, if you have a background in electronics and have the equipment to do so, I believe that you can troubleshoot this issue and resolve it. The HDMI port is not the most stable of interfaces, that is why I always tell folks to turn off and unplug the TV and all devices until the HDMI interface is connected to the other device and then plug the TV and device in and turn them on. I hope this helps, Thank you, Shuttle83 http://www.electron-age-technologies-llc.com

I do not know what your problem is as you do not even describe a problem, but I dare say capacitors do not need to be bulged to be deffective.
Usually the ones closest to heat source are the ones to dry first; bulging can be result of a too strong current running through them too and not neccessarily related to heat.
Usually they are large and close to the connectors that carry power from the power board to other internal boards.
Other capacitors may also be affected, of course.
You can try your luck replacing them in order, bring the TV to a specialist or start reading the theory of repairing SMPS - you can find it online, an excellent read if you really want to get into it.
