I picked up this 36" beast at no cost. Its in perfect shape. Owner told me it would not power on via the front panel switch or the remote.
Any ideas where to start looking? I have not tried it myself yet, nor have I opened it up. I am an electronic engineer and reasonably well equipped at home with test equipment, although my strengths are more radio/audio.

Tv might have more dead parts than just the safety fuse.If tv have only a power supply board fuse only they can do it for u wright there take the tv aparts and replace the tv power supply safety fuse like 15 mins job and will cost u like $40 dollars take it to any tvs repair shops.
It sounds like you have a switch problem at the front panel of the set. If a switch gets stuck internally the micro is trying to process the command and won't respond to any other commands. The only way to find out is to go into the set and desolder all the manual switches and see if the remote will work the set. It has a seperate detector for the remote. Thanks for using fixya. Good luck
Hi Dave: "My JVC 36" TV will not power on and has a blinking power light."
That means that the protection circuit has started because a fault had been detected.
If this happened after a power surge it is likely a faulty PSU board.
Try first leaving the set unplugged from power outlet for few hours, this will drain power, reset the protector, and fix problem related to accumulation of electrostatic charges on PSU power capacitors.
If unplugging does not work, that means that there is an internal fault. If this happened after a power problem of some kind, that means that probably one of the capacitors on powr board had blown, and must be replaced. The TV must be tested by a technician to find the fault.
Most of the time the cap you speak of tends to buldge at the top of it . The spark you speak of is just the two contacts joining . With the tv unplugged you can clean them with a fine sand paper and blow out any dust if you think this is your problem. The picture tube would not cause this problem , Only real way is with the tv on and looking at the pictures brightness and color . Also this tv shuts down due secondary shorts - vertical problems - horizontal problems . Any more help after you check it out let me know . Good luck
If it works at 3 different houses, but not yours, then it might be the electrical wiring at your house. Try a different outlet in a different room. Make sure your electrical wiring is not too old, and needs to be updated. Check your circuit breaker panel, does it need to be updated?
it sounds like a convergence adjustment problem. If you hava book on the tv still read it, and it will tell you what to do, other wise, look for a convergence button on the front of your tv, and take the remote and push menu to bring up setup, and go convergence adjustment click it and hit the conv. button on the front of the screen. there should be to lines going vertical and horizontal, these are the limes you adjust with your remote, you have to adjust the red and blue, the tv should blink to let you know which color you are on. when you have them lined up right the line will be perfectly white. hope this helps
