    My son bought it 2 christmas's ago. He set it up. It was plugged into a surge protector. My wife turned it off on the tv itself and had the shock. Our house is dry as this happed in the winter last year. I'm just now getting around to trying to get it fixed. Money has been tight. What if anything could of been done to ground the TV?

Try disconnecting the unit from the wall power outlet and let it sit for some minutes - or fifteen. Depending on what exactly happened inside the TV, this might be enough to clear the error.

If there's a permanent shutdown mechanism in the TV, you might be able to clear it by resetting the unit: this usually involves some "secret move" which the technical support will have to tell you. On most units it's no great secret, and involves powering on while keeping the standby button pressed or keeping the ON/OFF button pressed for 7 seconds, things like that.

Finally, it is unfortunately possible that the static charge sent an overvoltage straight into some core IC chip. If this happened, the IC is gone and needs identification and replacement.

Normally it should NEVER happen because the external part of the TV should be electrically insulated. You only get static hazards from OPEN devices and this must be labeled ("No user serviceable parts inside / Risk of electric shock"). If a static charge can get from you to the device's innards, the same way you could get an electric shock from the power lines inside the device.

An "ungrounded" device should simply not give any static shock, because there's no path to ground through the device's insulation and shield. If it does give a shock, the path exists - and security regulations mandate that it should run well clear of internal circuitry for obvious reasons.

That's why I think you triggered some sort of "last line of defense" circuit which essentially disabled the TV to weather the storm, and you only need to reset the circuit. Otherwise, you have a potentially serious design flaw in the device which should be reported to the firm.

Under these conditions you may be able to recover repair expenses or even get a new unit, depending on your local law.

Whomever set this unit up did not ground it properly. Have them come back and be sure that it works before they leave the house. Even try the static charge zip again, to ensure that they have it grounded properly.

If they cannot make it work, demand that they repolace this unit. You paid a lot of money for it, and it should work first time out.

Just because they sell these things doesn't make them experts on setting them up under various circumstances.

Repair Sony nsx-40gt1 tv, no picture, 2 red blinking lights where normally green. Is the power supply board bad, t-con bad or main board bad. Who sells repair manual?


Hello Eric,

shopjimmy has the circuit boards and gives live support..

Check out the URL below.

Also consider getting an anti-static wrist band... so you don't destroy good semi-conductors with tiny static sparks.

Further information on that is under "ESD"

47LC7DF, Green light comes on, blinks with remote


When you say that you have replaced the main board i assume you mean the power board? If the green light comes on and blinks when the remote is touched it was never a issue with the mainboard, if it was you wouldnt have any signs of power. In most lcd tvs you have the main board which is normally the power board, the signal board which recieves signal and hold settings of the tv which can be all in one, the other is the inverter board, which scrambles the signal to what you see on the screen, and next we have the back light which lights the screen so you can see the picture, sometimes in certain models as i have learned you can have power/inverter boards which means the inverter and power are all on the same board, in your case i pressume the inverter board is seperate board and probably the issue you need to address, you can buy these online probably the same place you got your new mainboard from. Hope this helps pls post bach what happens.

I have sharp 37 inch LC-37D44U MY PS3 is not working with it it green lights keep blinking power light and OPC. BUT THE HDMi ports work beacause i checked it with other devices. so i dont know why its not...


Does this happen when you input certain signals to the HDMI2_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.
