What kind of connections are you using?

If component (red, green, blue) double check to make sure they are seated properly. I'm thinking it sounds like the blue one got loose.

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 ?

Blinking light is an error code. Count the blinks before they repeat. Check your manual in the troubleshooting section. If you can't find it, contact a Sharp service center or try and get a service manual. Reset info is also in the user manual but you can't do it if your set doesn't power up. Are you sure about the power board?

My Sharp 13" turns off in 5-7 secods.


Likely power supply--bad caps etc----5 years and 13? inch---cheaper to replace most likely---if you manage to get it apart look in power supply for puffed up on top caps----age of set makes this possible and not real expensive or difficult to repair.
