    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.

My panasonic th-42pwd8uk tv wont power on. When I press power it clicks to turn on then clicks again and the screen never shows up. No red lights no blinking lights just a solid green light.


Check the capacitors and replace the power components. It is an easy fix if handy with soldering electronics. Tv Repairman may charge less than $100.00 bucks to fix it !
Good luck

My 29 inch crt has sound but no picture


Sounds like a high voltage power supply problem. With the TV on, check to see if CRT has a static charge on face of screen by placing back side of hand in front of it and feel for static charge. Also you could hold a piece of tissue paper in front of the screen to see if static electricity from the CRT attracts it. If no static charge is present, the problem is more than likely in the high voltage power supply. Unless it is something simple, like a loose connection, it would probably be cheaper to replace the TV. Do not probe around in the HV power supply while the TV is on--it could prove deadly.

Flashing green power light


If the model indicated here is right It could be in the power supply and this model sometimes fails where light just blinks--that could be also convergence issue--in this model there is a way to disconnect the power going to the convergence board to see if set will then turn on.

My Compaq Presario SR1303wm PP150AA cuts off by itself and a little green light on the back starts blinking


it could be overheading or it could be a power supply going bad. where is this green light, is it adjacent to the power cord, like on the back of the power supply unit, or is it adjacent to all the ports?

if the light is on the power supply then replace your power supply. if the light is adjacent to the ports, then remove the side cover of the case and blow the dust out of the cpu heatsink (the cpu heatsink is pretty big, usually aluminum, fin array, topped with a large fan). do not touch any microchips inside the computer, and discharge any static electricity before acessing the inside by touching an unpainted part of the case right after you have removed the side cover. if the heatsink is not dirty, and all the fans are working and well ventalated, then it is likely the power supply.

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.
