It is not a fuse, since if the fuse was bad, the power LED would not light at all. I have seen that symptom many times and I usually find 2 problems which cause this. On some sets, one of the larger caps in the power supply's secondary side degrades just enough that the set will not start. On other sets, I usually find that the small transistor that turns the relay on has shorted out, and the 11 volt zener diode next to it is usually shorted too. The transistor is a very small surface mount transistor, so the set should be serviced by a qualified tech experienced in JVC sets.

LC-40le550u no picture... green light on


if powers on and has no video and no audio could be the main board, but first try this :

take a flashlight, turns on the tv and try to "see" the image while light up the flashlight against the screen , if you "see" something you have a bad back light inverter board.

below the posible parts number :

MAIN BOARD : Sharp 9JY0140CTJ05100
POWER SUPPLY/ BACK LIGHT : Sharp 9JY0940CTJ05000

TRY TO LOOK FOR AT :

I have a pioneer DTS 96/24 multi-channel SX316 that just stopped working. Is there a fuse to try and replace? If so, where.


Remove the top cover and follow the mains cable into the unit. Any fuses should turn up near that. Make certain the power cord is out!

I have an RCA 52in Rear Projection TV. One day it


There is a sub-board in this set that powers the convergence circuit. Often a big Ic shorts, two diodes and finally the main fuse. not something you can fix yourself.

Tried plugging something in :(flashing light.no pwr.


you have tripped the tv's safety power down feature, try unplugging the tv for 15 mins to an hour then try to turn it back on, if it still ceases to function, the tv will need servicing.
