If your TV is less then a year old, still cover under manufacturers warranty, if not the solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.
I service these power supplies, for more info write to jah2mil@hotmail.com

No picture no sound, red light on, left unplugged over-nite, no change. Turn on/off a number of times, got back perfect picture/sound. Turn off, same problem, no picture/sound, red light on. Tried...


First if the model number is right here: When the red light is on about 80% of the set inside is powered up and running all out.

On these sets if you turn it off and the red light does not go out one of the relays on the power board is engaged or stuck in the closed position.

If I remember this model it has three black rectangular plastic relays on the power supply board(follow power cord into the set to see if this is the case.)

Relays have voltage and type marked on top (like 12 vdc etc).

Carefully with back removed what I would do is with something NOT metal tap on each relay until (with set turned off) the red light goes out.

That is the bad relay----if set has 3 I usually replace all as only 4 solder connections each and they are not real expensive.

I saw one of these sets where the customer had been gone for a month and when she returned set appeared to be off but Red light for power was on.

The set was so hot I tapped on the relays and then when I knew which was bad shut the set off and unplugged it to let it cool off.

I am saying if you leave the set plugged in and the red light is on There is the chance it may overheat to the point where you could have a fire.

Let me know if you have questions.

a tv has two components, firstly a power supply produces high voltage to trigger a line transformer, in turn a transformer produces smaller voltages. firstly check if the ht is constantly been produced from a supply, if this is there than go to a line transformer, and check voltages at the output.

No sound, no picture and a red light blinks on front panel


If I remember right the set is blinking a code, dont remember which code, but what happened something on the power board failed and knocked out the 5vdc regulation? The power board will most likely need replacement, this should be done by a qualified technincian or someone who knows how to dissassemble/ repair set.

No pic or sound


All the TV's have a fail safe now a days. It looks like that there is a problem with color management or the picture tube. If this is a projection than I could have said that it is a certain that it is to do with the color management. When Tv tries turn on it get a signal that there is a problem when it does the diagnosis prior to turning on and it stops. I am leaning towards the Picture tube as you didn't mention that the power light goes off after it tries to turn on. Please get it checked. good luck.
