    Have the same Sharp LC-15AV4U 15 in. LCD Television, it comes on with good picture and sound for about 4 seconds, then shuts off. Power button will repeat this cycle indefinitely.

    Looking for a schematic or service manual or hint as to suspect component in the power supply.


    Thanks!

    The TV just "Blanked" out. It will not turn on

  • SharpMan2006 Apr 02, 2008

    Sounds like a lamp error.... either a defective or broken lamp within the LCD panel itself, or you have a bad inverter.

I took one in for repair with the same problem. Turned out to be a capacitor. (C431) near backlight transformers. Mylar 184 @ 250V. Replaced C407 also to prevent same problem.

The main tv Tuner signal board it is dead or it have problems,but tv still usable.Tries push the remote power switch off/on again everytimes OPC/Power LEDS lights flashes.Have to do this maybe 3 or 4 times for the tv to have a lite up LCD screen panel backlight to make the tv Tuner signal board to work again,for the tv to work.If still have same problems after 3 or 4 times power switch pushes off/on still have OPC/Power LEDS lights flashes.Mean the main tv Tuner signal board it is dead and can not be trying to save it.Tries websites like Shopjimmy.com,Ebay.com to buy a whole new refurbish tv Tuner signal board for the replacement.This solution 100% will work,if ur tv main Tuner signal board still have life left in it.I do this every few days out of a week for my 46" Sharp Aquo LCD tv set,tv it work all the times.
