No picture, no sound.

Power comes on but no picture. You can hear clicking when pressing the power button.

On back of set, when looking through cooling slots you can see some green LEDs...four, I think. One blinks constantly, and the other three are on steady.

I love this TV and I really would like to fix it. HELP!

When I press the 'power' button, I hear it click, but no picture comes on. I hear it click a couple more times, then it stops.

If it clicks then goes to standby, then the fault is in your power supply circuit. If the sound comes on then the fault is in the line timebase circuit. Aquick way to check the line circuit is to place the back of your hand about 1" from the screen as you switch on, you will feel the hairs on your hand standing to attention.

My TV does not power up when the power button is pressed.

It's sounds like your lamp or backlight has went out, I suggest reading your manual for service info and look online for a local repair shop.

NO PICTURE, NO SOUND On My Plasma TV.

Should have been 3300 UF 10V caps that were bad? Shouls have been replaced with 3300UF 18V. 50V is huge. If it was replaced with a 50 the polarity may be wrong or the cap it too big to be seated property. Sometimes the caps just dry out and even a normal looking one will be the culprit of no OSD. Are you getting an LED fault code blinking? That should be a red led. Do you hear the relay clicking.? When you replaced the caps did you charge them? Just plugging in the set without trying to power it on for about 20-30 mins. I may be able to help you

The power button on the front of the tv lights up but no picture or sound

Was there a color or sound problem prior? If not you can replace convergence amp and vertical output these are the main problems with this set. No high voltage is what's happening sounds like. Look to see if after you press power you hear sound coming from inside. If no sound then converg. if sound then vertical

Loud electrical sounds

It sounds like the Power transistor that drives the High Voltage Transformer shorted out. The rapid clicking sound you are hearing when pressing the power button now is that of the power supply starting to come up, detecting a short circuit and shutting back off again, preventing further damage. It is likely that the HV Transformer is shorted as well which usually causes the Output transistor to fail. Since the set is only 2 1/2 years old, it is probably worthwhile getting it to a repair shop as long as you have been very satisfied with the picture quality up to this point. If the picture size was larger than you needed, you might consider going down to a 37" LCD HDTV set. Toshiba is tops in this category IMHO.
