TV has worked flawlessly for years. All of a sudden today I heard a loud snap sound and then there was no picture. Pressing the menu, volume, channel buttons do not bring up anything on the screen. The tv clicks when I turn it on and the red light comes on but thats it. I took the back panel and checked the 3 fuses and all were good. Any ideas? I hope its worth fixing....

Of course, this sounds as if something has failed dramatically.
Perhaps a power supply or voltage regulator of some kind.
It might be as simple as swapping out parts.
However, that is best left to a professional.
If my 57f59a (knock on wood) experienced a similar problem here is what I would do for starters.
THIS IS WHAT I WOULD DO. YOU SHOULD CONSULT A PROFESSIONAL REPAIR PERSON FOR YOUR OWN SAFETY.
Unplug the television.
Remove the top portion of the unit from the bottom portion carefully following the instructions in the owner's manual.
This isn't difficult at all.
Next, visually inspect the electronics for obvious signs of burning.
Perhaps the odour could help detect the problem.
With a little care the problem could be identified before the professional repair person is given the task of repair.
KEEP IN MIND THAT CRT REAR PROJECTION TELEVISIONS RETAIN HIGH VOLTAGES FOR A PERIOD OF TIME AFTER POWER IS DISCONNECTED.

So I've done as you said. I took the back panel off and the top section but am having no luck finding any sign of damage. All the capacitors look good, no burnt areas, or any smell for that matter. I'm really hoping to diagnose and repair it myself as the tv is hardly worth the money to have a tech come out and fix it.

Please keep us informed.
Your trials may help someone here someday.

You will need to replace the lamp on your projection TV, that is how mine went, if you need a local supplier I can forward their email or web page. Brian

This is a crt projection tv.
There is no lamp to replace like an lcd or dlp projection tv.

Wish I had some news for you guys but I'm not having any luck. No blown capacitors, no burnt fuses, no burnt areas, no cracked solder joints that I can find. Any other ideas I could test or check for? Thanks for all the replies...
