    Is PS failures pretty common with these TV's. If the PS is bad would you recommend board level repair, repair/exchange pool or a new power supply?

    Thanks for your help. So that you get credited, I'll go ahead and close this one, but one final question. Is there any chance that the LCD is out and if so, what is the best way to check?
    Thanks again.

It looks like your power supply might not be providing enough current to get the LCD to power up. This LCD needs about 3 to 4 amps to work properly.

    I would suggest to check the capacitors in the power supply for dry or leaky conditions, specially the one that filter the 5 volts.

  • Jaime Hernandez Apr 12, 2008

    PS failures are common on LCD and Plasmas.

    It seems that is hard to find replacement parts, so I would suggest a board level or component level repair.

    You might also have to check the inverter boards as well for proper functionality but to get to do that you will need to have a working PS.

Diagram where fuse is in the polaroid flm-3701


There is a fuse on the power supply board. It is labelled F1. It is a small cylinder near the AC connector. The F1 fuse is 5A 250V. How ever, capacitors are more likely to fail on this television.
The Polaroid FLM3701 has a problem with capacitors failing on the power supply board. If enough caps go bad, you will get no power. Not even a power light. Any capacitor that is swollen is bad.

Hi, my LCD Polaroid FLM-3701 went through a power outage and now doesn't get power any more. The power led doesn't show any light. I saw a capacitor repair kit available, and four 680 uF capac


The power supply fuse should be next the the ac input plug on the power supply. It should be a long cylinder type fuse, probably a T6.3AH/250V. You will want to replace those caps ASAP

Where is the fuse in a 3701 LCD Polaroid TV/Monitor


In the Polaroid FLH-3701, the fuse is located on the power supply board, next to the AC power connector. It is a small black cylinder. It is labelled F1. Value is 5 amp, 250 volts.
A fuse does not blow for no reason. Most commonly a fuse will fail because of a short someplace on the board. I have this same TV. The fuse blew. The reason was transistor Q6 had shorted. There are two identical paired transistors on the output side. Q6 and Q7. They are both Infineon 11N60C3 MOSFET transistors. Check those for a short. There may be a burnt smell.
More commonly, this TV will fail because of bad capacitors on the power supply board.

Blue LED light comes on but nothing else happens when turned on


It can be the main board or the power supply, look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
