Question about Polaroid FLM-3734B 37 in. LCD HDTV

1 Answer

37" Polaroid Television repair please walk me through it.

I need help. I took the back panel off. I see two boards the top board has some black ribs on it that look like heat exchangers. It is smaller than the bottom board. I see two green capacitors side by side on the top board. Are these the correct capacitors. The is another larger cap. about an inch below these two should it be replaced also. Or am I looking at the wrong things?

I think your looking at the right thing. What does it say on the capacitors? 10v 1000Uf??? If that is what is imprinted on it then you have the right ones. Use 35v 1000Uf as replacements though.

Polaroid 37 inch lcd will work for about an hour then only display colored vertical lines...still has sound though, tv was given to me I build pc's so a fix is not out of the question, but is it worth it?...


That can be the T-CON board, main board that send the LVDS to the T-CON, worst case will be the screen itself. You can try reseating the ribbon cables between the LCD panel and the T-CON board to see if it help first. Post back what you find.
See example of bad T-CON/LCD screen in my guide.

I have to turn the tv on and off a few times


Just had the same type of problem with a Polaroid 37". Turns out it was two capacitors on the display board. When they go bad, they either leak or bulge at the top. They have to be replaced. You have to take the back access panel off to get to it. I wish I could give you step by step instructions on how to do this but I don't have them. Toshiba may also put theirs together different than Polaroid does. It only cost me about $5.00 and an hour to repair mine. Hope yours is as easy. I hope this helps you.

Polaroid FLM-3734B 37 in. HDTV LCD Television has a black smudge in the picture. The smudge never moves and is there no matter what we are watching. I fixed the sound problem, but now we have this.


Without actually seeing the problem, I can't be 100% sure, but this sounds like a defect in the LCD panel itself. Is there any possibility that you can post a picture of the problem? That would allow me to confirm the problem. Please note that if the panel is the problem, the set is not worth the repair as the replacement panel costs $2209.15 plus shipping.

I Think NO expert can help this problem because it free answer


I think I may finally have the answer for the "black screen of death" for the 42" Polaroid LCD televisions. I was having the same issue with the screen going black after a couple minutes of being on. I would shut it down then turn it back on and it would work again for 5-10 minutes. On the "power board" which is the board on top, there is a little red light that turns on when the screen would go black. above that there are 4 little switches, the lower on says BURN. I simply switched that over and the television has been working for 2 days for 8 hours + each day. Hope this help. Let me know

I hooked my laptop up the to my tv the other day and the tv went black. Now only the 'red' light comes on - no picture. Does anyone have any ideas on what happened and/or how I can fix this problem?


Common problem with Polaroid 32 and 37" television. Problem is most likely the control board, at cost of around $400. physically disconnect power to television. keep disconnected for 30 min. Plug TV back in and turn on. That may fix the problem temporarily, but more problems are sure to come...
