Polaroid LCD Flat Panel TV

I would first check the power supply. Check the main fuse, if is blown and there was no power surge from an external source, the supply board has some serious problem. If the fuse is fine measure the output voltage of the power supply board. Check for any swollen electrolytic capacitors, they are the number one cause of every LCD failure I have come across. I just fixed a Polaroid FLM1514 which has a 2956C Ver 2.0 power board driven by a Fairchild CM0765. Turns out the VCC capacitor was bad and not even swollen, sowpped it for a 47uF 50V and presto.

GOT SAME PROBLEM NOW IS THERE A FUSE WHERE POWER CORD PLUGS INTO THE SET ON THE BACK MINE HAS A GLASS FUSE NEXT TO THE PRONGS THAT COME FROM TV YOU HAVE TO USE A SCREW DRIVER TO POP IT OUT SHOWS A PIC OF IT IF YOU DON'T SEE IT DON'T TRY TO POP IT OUT

fuse

check fuse on power supply, it is covered with shrink wrap.

Remove the power cable from the back. With the 3 silver prongs exposed you should be able to see that the same black plastic receptical that houses the power cord, also houses the fuse (on the left side). You will need a small flat tip screwdriver to open the fuse compartment. Good luck!

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.

What kind? Is it Polaroid? Does it have power? If no power, check short out fuse next to power supply on back of TV! Further help refer to

If you have no power light at all on the front of your tv. Check the fuse by the power coard.

If you have a red light only and have the dark power board with black heat sinks. check the fuse in the center of the power board.

if the light turns blue when you hit the power button but no picture and have the dark power board replace the 2- 1000 mfd 10 volts caps with 2- 1000 mfd 16 volt caps at 105 deg.

need more help let me know

Power supply must be something wrong. You may need to bring it in a service center near you.
