37in sharp lc-37d44u, green flashing power light, will not turn on.

Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. Check all the CCFL lamps for darkened ends. 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. http://electronicshelponline.blogspot.com/ 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.

Look at manual should be there

Hello,
Power supply board just die.It can be dead at anytimes.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

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?

Hi i have seen this before sharp hdtv's are known for having the internal power supply go faulty

Backlight invertor is most likely cause of the problem, in rare occasions defective CCFL lamps could cause similar symptoms. Replace defective parts, reset lamp error counter and you good to go.

Does this happen when you input certain signals to the HDMI ports? Or all signals (e.g. 1080i, 720p, 1080p, etc.)? And which ports are affected - side HDMI, rear component, etc.?

I had this issue and Sharp sent out a local repair tech to install a new main circuit board, then two weeks later, a new side board (where the side inputs connect into the system)... their first visit allowed my TV to accept signals in the rear HDMI ports (all signals worked well), but then I couldn't get a signal processed via the side HDMI port. At first, just 1080p would not display (caused the OPC/power green light blinking), and after a few days, any signal hitting that port would cause the error lights to come on. But as I said, eventually, a new side board resolved that issue.

try accessing tv through the remote control.

i hve the same problem. I turned on my Sharp Aquos lc-32d62u HDTV last night for the first time, but it is black and a blinking green light.
did you find a solution?
