Sylvania lcd tv


If a fuse should blow up, there should be a reason for it. If you replace the fuse without rectifying the problem and switch it ON, the newly replaced fuse too will blow up. Before replacing an other fuse, find out the reason and rectify it. There should be some shorted component/s at its main power supply board. Check and replace them. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ It has schematic diagram of power supply section to many televisions. Pull up older posts by its left side bar. Problems to Sylvania too will be there.

Turn on


Three thoughts---check for short to ground with fuse removed and power off (unplugged) on both sides of fuse.

Use a original type fuse---generic ones often blow for no reason.

Consider replacing the board if you can confirm issue is on it.

Have a vizio 47" vo47lfhdtv10a,


Hi,

Problem is in either power supply or the Y-Sustain board.

The Y-Sustain is a relatively large board out of which go connections to the side of the display; it's therefore closer to either the left or the right side of the display, has at least one rather large heat sink on it and fat power cables connecting it to the main power supply.

Often there are fuses on that board - one or more. Check those.

if they are blown you can try to replace them, but expect them to blow again - usually the whole board needs to be replaced.


Hope this helpout in solving the problem...

Hi:
This is the X-systain board replace this board and your problem will be solved. The part number can be found on a white sticker some where on the board. Get the number and google it or enter it on E-Bay because alot of shops sell these boards when the get units with bad screens. Or try www.shopjimmy.com for a new board.

No, your done. Now replace the Y-Main, that's the large one you found the fuse blown on and replace the two buffer boards that the Y plugs into. Those are the two at the far left. The part numbers are on the boards. So that's 3 boards you will need. sometimes they sell the buffers together as a pair which is cheaper. DO NOT buy from second hand resellers. Always buy new when it comes to plasma sets.

The fuse in my polaroid tv blew. It keeps blowing the fuse when a new one is put in.


The odds are the circuit board that your putting the fuse in is shorted out. I'm guessing that it's a power supply board.

Disconnect every set of wires going to the board. Put the new fuse in. Plug in the power supply board. If the fuse pops, then the power supply board is the problem and has a short somewhere. Most replacement board can be found at a good price at Shopjimmy.com or Ebay.com. Just make sure the part number on the board matches up.

No pic but sound


I think you probably mean the Y-Sustain board which does have fuse which can blow. This board is on the left hand side (as you look from the rear of the TV). Occassionally other factors can be responsible for this fuse to blow such as the buffer PCB which works in conjunction with the Sustain board. An established repair service centre or a supplier on-line will porvide a replacement for you.

Power cut off and won't turn back on


The board you need to replace is the power supply board. The board# is BA71F0F01042. Your power supply board should have the same number on the lower right side of this board.
360211d.jpg The problem is the 6 Transformer Inverters that power up the LCD screen. If one blows out, the TV will go into protection mode like it's doing now. All the Funai TVs are having the same problem. Because, it uses the same parts.
The board is hard to find right now. Only three places I know of to find it.
Ebay,
Discount-Merchant.com,
and Shopjimmy.com
Sadly, nobody has them in stock.
I wish I had a extra board to sell you, because I know how to repair it. I have the schematics diagrams and part# for the pieces on the board.
If you ever come across a replacement board, let me know. I would like to buy your old board. Here's my e-mail, www.dsacco86@hotmail.com

No power to Samsung FP-T5084


I had the same problem twice with my Samsung FPT 5084 and it was the 12 AMP fuse on the power board both times. The bad part is you have to remove the whole back plate to get to it but once off it sits on the power board (dead center) towards the lower left hand side of it. Replace the top fuse or you can replace both. They're just regular ceramic sealed 12 AMP fuses that cost about 50 cents each.
