I had the same prblem. Was told it would cost $600 to $800 to fix. I spent less then $5.00 on two bad capaciters. Thanks

My polaroid flm 3732 tv wont turn on. the red light turns blue then back to red when i try to turn it on.


Have you tried the capacitor replacement trick here: http://www.fixya.com/TipsAndTricks/ThreadView.aspx?thid=741402 ? Use the method described (two places - look at both) to open the back of your TV. Look on the upper board (the power supply - where the 110 vac goes) for damaged capacitors as witnessed by their bulging tops. If they look ok and nothing else on the board is obviously damaged, I would go ahead and replace the three capacitors there. Two located near the center top of the board are 1000 micro farad 10 vdc electrolytic and the other right below the first two near the center of the board (a bit larger) is 1000 micro farad 35 vdc. Replace them all with 1000 micro farad 35 vdc (or wvdc) electrolytic caps - you can buy them from Radio Shack for $1.50 or so each. This assumes that your FLM-3732 is similar to the FLM-373B that I have. Good Luck!

I have a Polaroid FLM-373B flat panel HDTV that buzzes when it is turned on. You still get sound from the selected channel but there is a background buzz even when muted and in all connections. Especially...


You have a faulty power supply. Check that the power supply capacitors are not bulging at their tops, or a brown liquid hasnt leaked out the tops of any of them either.If so, replace the faulty capacitors..Second option is to buy a power supply online

Hi all. I came across this forum after "Googling" this particular model ilo TV. (LCT27HA36) Like a lot of you, mine would not turn on. It was just like lambon48's TV. Since I could not find an answer online, I took it upon myself to solve the problem. I am a retired radio engineer, and have experience in repairing a vast assortment of electronic equipment. The problem with my TV was isolated to the power supply board. I found several capacitors to have bulged. That is, the tops were swelled outward. This usually is a sure sign the capacitor is bad. The ones that were bad were all of the 1000 uf capacitors and one 470 uf capacitor. Now these caps were rated at 16 volts and 25 volts. When I replaced them, I used 35 volt rated capacitors. These caps can be bought at Radio Shack for about $1.60 each. It cost me $10.50 to fix my TV. I recommend you having only basic knowledge of soldering to do this. Just take your time and notate how the caps are installed before you remove them.. Please make sure you install the caps properly. That you put the positive and negative legs of the capacitor in the proper holes. If your board is like mine, the positive side is marked on the circuit board. If you are hesitant on soldering, I bet you know someone who can do this for you. Good luck.

This origional post has been up since June 2006. The answer(s) about the 1000mf capacitor are right on target and has helped people even up to today (Aug. 26, 2008). It worked for me and the following might help others.

First find the power supply board. It is the one with the power cord attached to one end (make sure you unplug all power first!). This power supply has about nine minature electrolytic capacitors in the output of the supply. There is a large electrolytic near the input (elecrtical cord). Disregard this one and go to the other end of the board. The 1000mf, 10volt component you are looking for is near the middle of the 9 or so capacitors on this end. It will probably be the largest in this group (because it has the highest electrolytic value of the group) and the board surface will have an I.D. number of C316 adjacent to it.

DO NOT ASSUME THAT THE CAPACITOR WILL HAVE ANY SIGN OF A BULDGE, DISCOLORATION, OR ANYTHING THAT WOULD IDENTIFY IT AS A FAILURE! In my case the replacement solved the problem but there was absolutely no signs on, or around the capacitor. After replacing it, I checked the old capacitor with a (ANALOG) multimeter. The test showed leakage across the capacitor. In other words it was still working but had a high resistance path through the capacitor. This is exactly what I expected because when I checked the output voltage of the supply to the other 2 boards, voltage was present but was reading about 1/2 of what it was supposed to. The markings on the front (output) edge of the board indicate a -24 volts between ground (pin 4) and pin 3. Mine was reading approximately -12 to -13 volts.

I hope this will help others. As a matter of interest, this is an electrolytic capacitor and you should notice that the component taken out is marked negative ( - ) near one lead. Be certain to install the new one with the negative lead in the same manner! Also, any replacement you might find with a higher voltage rating should be at least 16 volts but a 200 or 1000 volt rating will work fine. Although, the higher the rating, the larger it will physically be. You probably would not be able to physically install anything over 50volt rating. The 35volt rating seems to be very available and a very good choice. With regard to microfarad (mf) value, 1000mf are very common but a 1200mf to 1500mf in a power supply circuit will work fine. Do not use anything less than 1000mf. Hope this helps others. This is going to contiue for this Phillips product until they all die.
