Does this happen when you input certain signals to the HDMIi have sharp 37 inch LC-37D44U - 2_bing.gif 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.

THe problem is in the set top box. Or common called the tuner box. IT looses the 5 volts to the main display and thus the monitor will go into a shut down state. THESE boxes are factory repair only and must be sent off to repair.

It may be in the safety shutdown due to shorts circuits in the power supply or in the backlight inverter board. You will have to open it up and check.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Power light blinking green,nopicture lc-32sb24u lc-37sb24u


This same thing happened to me, but not until I fiddled with all of my remotes, trying to see if it was an input issue, battery issue, etc. I finally unplugged the tv from the wall and plugged it back in. Nothing. Then I went to take 5 minute ****. When I finished, the Power & OPC lights were blinking, and out of sync. I pressed the power button at the top of my TV and got a picture.

How many times per second does the POWER led blink? (dont worry about the OPC).

1x per second (constant, steady blink) = bad inverter/lamps
2x per second = bad power supply
3x per second = bad main board

There isnt really anything you can do to fix it yourself, youd have to call Sharp to locate a local service center.

No POWER


How many times does the POWER led flash per second? (Dont worry about the OPC).

1x (steady constant blink) = Lamps or inverters
2x = Power Supply
3x = Main Unit

If i am reading it correctly, looks like the POWER led is flashing 2x, which means it is a power supply failure. Either way, your TV needs to have a board replaced, there isn't anything you can do to fix it yourself. Try locating your local sharp authorized service center to repair your TV (1-800-237-4277)
