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 ?

I have the same problem with my 37" HP which is the same as Sharp Aquos, it's bad backlight inverter boards, the screen comes on for a second then nothing, no menu, no channel change indicator then turn it off and you hear the clicking of the power supply about 10 seconds after.

My TV wont switch on


A common and very likely problem is your power supply board, you can buy them refurbished online and replace yourself if you feel comfortable working around elctricity and high voltage. I generally do a component lever repair wich is much cheaper, but without the proper tools it is not wise to do.

Remote Control Problem


take the batteries out of the Sharp remote press and hold the POWER button on the top of the remote for 5 seconds. Put batteries back in. Make sure that function is set to TV. Should work - if not call Sharp. If you are inside the original manufacturer warranty they will replace remote
