SOURCE: tv shuts off spontaneously. red power light blinks.

Sounds like you may have a bad inverter board. This board powers the back light on the lcd panel. This board may be replaceable or the complete panel may need to be replaced. If the panel must be replaced you will be buying a new tv. Very expensive part. If the inverter is available seperatelly then it may be worth repairing. You should contact a Sony ASC for an estimate. Good Luck

SOURCE: Blinking red light

It appears in all cases that the power supply needs to be service. The blinking light might indicate that there are shorted parts or the voltage is low or a combination of both.
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

SOURCE: tv will not go on

On my GE Tv/VCR Combo I had a similar problem. Try holding down the Power button on the remote for at least 7 seconds. This disengages the parental controls. I found this solution on another website after my tv stopped working after my 20 month old played with the remote for a while. This solution was not in manual. I am assuming that he held down the power button for 7 seconds to engage the parental control. Hope this helps!

It sounds that there is some overload within the circuit, and is related to some fault to it. If you wish to get more details, check this link. http://electronicshelponline.blogspot.com/ Selecting the view option, either to Mosaic / Time slide, can be selected by the drop-down list, at the top left of the display window, will make surf easy.

Mitsubishi big screen HD 1080 series model WS-55809. it switched off one day. and when i turn it back on it switches right back off. red light in front. what part do i need to fix it/


That model does not have a red light---Green.

If set powers up for a few seconds (green power light) and goes out do the self check the model indicated has:

On front of set (not with remote) press and hold both the input and menu buttons for at least 5 seconds and release both.

Green power light will blink a two digit error code like 2 blinks, 2 blinks a pause and repeat it several times.

Let me know what error code you find (if you have unplugged the set that will clear all errors and you have to plug it in and try to turn set on again---when it fails do the self check)

I push power button and my 1080 series 42 in. mitsubishi big screen shuts right back off.


Most of these sets have a self check feature:
UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device”(device sometimes is called input) and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

Let me know what you find and I will tell you what it means.

TV turns off and power light blinks unpluged andd still does it.


Likely to be the STK convergence chips causing a protection circuit to switch the TV off. Have you got any onscreen convergence problems (i.e, colour fringes)?

No video, shuts off then back on


I checked Toshiba's website and found the manual for the set. The self restarting was indicitive of a lamp failure. The red light was solid while the green light blinked. It would then restart 8 times before both lights would then begin blinking.
