SOURCE: POWER AND OPC LIGHT BLINKING GREEN

The condition of your TV called power supply overcurrent shutdown that"s why you hear a click. The TV is going into a protection mode to prevent further circuit damage. That's why it will not turn on or not powering up. I would concentrate on the power supply section board. Bad regulation of the incoming voltage could caused this issue although,there is a capacitor across the incoming line and nuetral.Maybe its leak or dry up and cause the problems,change it out with one of identical rating . Although now you are getting into dangerous area,especially if you have no electronic experience background. It could be also be a loose ,crack or cold solder joint,a blown fuse,fusible links or other component .It could be one of several boards.Unfortunately the level of sophistication on these TV make it virtually impossible to diagnose them further without taking them apart and probing around with a multimeter and other tools.This TV is handy enough to take to a repair shop find a good one.You will probably have to pay $75 to $100....

Hope this may help you..

Regards,
VOTIT

SOURCE: power supply bad on Sharp Aquos LC - bad board - schematic to ID?

Buy the green light going on means Standby is ok. Next, would be to locate the plug coming from the main board to the power supply and find the post that says PO which means power on. With your meter on that post, press the power button as see if the reading goes High, if it does then the main board is able to turn on the power supply. Next, find the plug on the power supply that goes to the inverter( the long board on the side) remove it and see if you have 24 volts coming out of the power supply when you press the power. If you do, then the inverter board is bad, if you don't have 24 v, then the power supply is bad. There are NO diagrams available for these set other than a flow chart if you can find one. A regular svc tech does'nt need a manual for these anyway.

Let me know how you do Kathy ?

SOURCE: sharp lc-22sv6u won,t power on. no green light.

Sound like the TV is in protection mode. This happens when a part goes bad inside. the TV turns OFF to protect the other parts from being damaged.
Most commonly it's a power supply related issue. A bad capacitor or transformer on the power supply board is to blame.
For a do-it-yourself fixer with electronic experience, a Service Manual is the best for trouble shooting the problem down to the bad part. Normally, you can find it over the internet for less than $20.

Sounds like Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
