You see the live help tech support? They should be able to give you the details, Im not sure what kind of adjustments are needed or not. So try that or repost the problem if not solved.

I have a WD 62525 tv that will not turn on, completly dead no lights or sound. replaced the main fuse on power supply board what else could it be?


you might need to have voltage checking at this time. if their is a dc output voltages at the power supply board.if none the main board will not turn on.then probably their is bad component at the power supply board.

REd background instead of black


It is low voltage in the screen driver board, probably a bad capacitor in the screen driver board or perhaps in the main power supply. The only way to tell would be to look at a schematic and measure the voltage and check the voltage source on the power supply board. If the voltage was low, replacing the board should fix your problem. If the voltage was normal at the power supply, then the screen driver board would need to be replaced. Good Luck

Toshiba 42wh38b Projection TV won't come out of standby


That problem is usually have 2 causes..Its either power supply board or main board..

Please take this steps on how to determine the problem:
1. Open the back cover.
2. Check the power supply output...It should have 5vdc for the main board..12vdc or 16vdc for the audio and 24vdc for the back-light inverter..
3. If those 3 voltage supplies have encountered voltage drop...The problem could be on power supply board..
4. If the power supply output is normal..The problem could be on the main board...
5. If the problem is power supply you should check if the capacitors are bulged on the top and try to replaced it..If you can't do that you can purchased new power supply board..
6. If the problem is on main board there is no D.I.Y repair on that so you need to buy a new main board that fits to your TV..
Hope this solution will be helpful..

Power light flashes red 6 times. No picture.


The common fault often points the problem being to the power supply or the main printed circuit board.
If you are tech-savvy, you can open the back of the unit and measure, using a multimeter, the voltages from the power supply printed circuit board as well as the main printed circuit board, if the power supply is sending insufficient voltages, its common that you will get the flashing red lights.
Also check for any blown capacitors on the power supply as well as any shorted resistors. I hope this helps.

I have a gateway 50 inch plasma tv that flickers. It started off with only flickering a short time but as time went by it would not stop. The flickering get less pronounced but will not go away. I have all...


hello. The problem you are having has haunted Gateway ever since they went into the television business. Here is a link to an article about the issue. http://www.techdirt.com/articles/20051214/0211209.shtml

Getting back to your set, I would definitely not put one penny into a repair. Instead, cut your losses and upgrade to digital, right now the prices are shockingly low. good luck with it.

I have sound but my picture is completly black


Not enough input (info) or u using cable connection or av, if av could be the signal not going in,
Bad convegence so goes into protection,
Bad vertiacal so unit goes into protection.
Bad high voltage block so no voltage to crt's
Blowed Horz transistor, so no difflection.
If seen some RCA with this problem deppending on your model..
If seen some mitsubitchi with bad ic's but dont' know your brand.
If seen sony with shudown defflection for burt resistor in power supply but can't tell no model.

You see I can gess all day but without the info, well I could be talking of a monator.
