Question about Polaroid FLM-3701 Television

1 Answer

Is there a difference in the Main Unit if the part numbers are: 782-L37K7-560C od the same, just 560B? I am trying to order a new board and mine is 560C, the one I found was 560B. I have heard they should not be any different. Is that true?

The "C" unit is probably a later version of the board with newer fireware, hardware, less bugs etc.
You can also get a "E" or "C" version of the board.
Try Ebay for a "pulled" unit.

Have vertical coulerd lines all acrose sceen

This could quite easily be your T-Con board.
The simple way to go about things, is open the unit up. obviously with power off and having grounded yourself first.
1. Dust off everything
2. Check main board for any capacitor issues.
3. not serial numbers and any other numbers you see on your main board and T-con board.
4. search youtube or internet for how to vids for your model of tv
5. if you discover that the problem is related to t-board, which it sounds like it is, then order new t board and replace.
6. Not hugely difficult. Just remember where all the screw go and don't get your screen scratched in the process.

My vizio VO47L FHDTV10A has no picture but vizio symbol turns white when I turn it on! I tried checking fuses and the ones I found were fine but mine doesn't have those three fuses everybody talks...

I had this problem with VT470M and the white light would come on but the screen would freeze on opening screen and then after a couple times the white vizio light would come on but no picture no sound. I ordered a new main board after troubleshooting all the voltages and it worked. trade in for 150.00. Well worth it. The main board tells all other things to turn on. The white light is your standby power which is good. Probably ur main board and ordering a new one worked for me.

LG 47LC7DF Power surge (lightning) blew out hdmi and rgb and pc inputs, still have antenna and av inputs working. Is this an expensive fix?

you will need a new main board, your set has several different variations. The cost of the replacement board can range from $100-$150 from reliable sources. If you decide to order a new board, you will need to find out the part # of your main board so that you are ordering the correct board.

Screen is showing a no signal, and is being fed from directv sat

Well try different inputs and also different sources.

The problem may be in the source, might be input specific or might be that the whole board in the TV was damaged, usually as a result of a surge thrugh the cable or antenna.

If the same result is seen with different sources, then you'll need a new main board like this:

Make sure to match the board number in your TV *before* ordering anything!

Try this place,

I the best place I know of to get parts at a good price.
There are a couple of boards that have different part numbers. You'll have to match the part# with yours. It maybe out of stock, but click on it. Then click on "find other products with this part number". Then all the main boards show up with that part number. A couple of them should be should be in stock.

Power loss

Try unplugging and then plugging the TV back in. If you can now turn it back on then you have a bad main board. If this does not make any difference then you have a bad power board. Hope this helps.

Well mine is now fixed.

$250 for the main tuner board and another hundred for labor.

I did find that there are some "like new" boards out there from otherwise damaged units. For instance a Big Box store damages a flat screen or exterior trim, the board is removed and tested.

The "like new" boards I found are about $150 with a 90 day warranty. The new board also has 90 day warranty.

The tech guy that posted here was correct. Thank you.
