Ok your going to need a VOM meter and a soldering iron (25 to 53 watt, not a soldering gun). By no sign of power Im guessing that there is no click or any kind of "electronic" noise from inside the set. Ok, safety first, unplug the set and once you open it stay away from the high voltage anode wire that goes to the CRT (picture tube). In side by the power supply locate a resistor that should be at location R607, it is colored white and has a value of 0.1 ohm. It is most likely open, if so then most likely Q601 and Q602 are shorted as well, you will have to replace them and it is very important to also replace the following (shorted or not) R644 6.8ohm I think 1/4 watt and VDR601 VDR602 and VDR603 One of them is color black and the other two are green. I think VDR601 is the black one but dont quoat me on that. Next go to the Flyback transformer largest transformer in there (roundish in shape) near it is the Horz out transister I think it is location Q591, check with your VOM to see if it is shorted, if so replace it. Once you have that done solder the pins on the flyback and the Horz drive transformer, again dont quoat me but I think it is location T503. If you have a ESR meter check the electrolytic capcapscitors. Hope this helps! Good luck! Don

Blue light but tv won t turn on

Try these troubleshooting steps:
- Try to power on the TV using the button on the TV and not the remote
- Ensure that the power cover is securely connected
- If you are using a power strip connect the TV directly to the wall
- Try a different outlet
- Can the outlet power any other device?

Good luck

** TV won't turn on.** No picture or sound. Please Help !

If the red light won't come on it is not getting power.First,try plugging it in to a different outlet,or unplug one of the gadgets you know is working and plug the tv in there.You are simply switching.If you know that there is power coming from the outlet and it still won't come on then you'll have to check the cord;don't go much farther than that without expert help.

TV turned off by itself and now it won't turn back on

If the tv has nothing happening at all when you try and turn it back on including any noise, your power supply is broken. If it is still trying to turn on or does make noise, an internal component has come loose or been knocked off, most likely to your picture tube.

No Picture - Sound

I just had this problem fixed. In my case, it was because the insulation on the CRTs was cracked, and when it would warm up, the shielding would separate and would let 5000 volts arc across the main board. This, obviously, damaged the board. The tech didn't catch the arcing right away, so they replaced the main board twice before they used a high-temp RTV to patch the insulation.

The power-cycling was a result of the damaged board.

The point of this story is that the broken part may be a symptom of the real problem.

I hope this helps someone!
