Re: Sharp 60" LCD Model LC-60E69U - No red/blue LED, PSU Seems OK?

Im open to ANY ideas on how to troubleshoot further.

Hello all!

I have a 60" Sharp Aquos LCD TV Model# LC-60E69U. Came home one day and no power light, nothing.

Initial inspection of power supply shows no obvious blown caps/fuses/diodes. 24V bus is fine, 12V bus is fine, 5V bus is fine. 24V and 12V bus did not drop much under a 8 watt load. I'll have to find a 6V light bulb to test the 5V bus. I have downloaded the service manual for the tv (linked here ) and have gone through the first two "basic diagnostics." All Check OK as per the service manual. It basicly had me check a few voltage regulators,...

poor_red_neck here, new to component level diagnostics when a simple blown cap/shorted diode/blown resistor isn't the problem. Hoping to fix a Sharp Aquos TV.
