    My TV is doing the same thing. Turn on - power comes on for a few seconds and then shuts off. Is there anything we can do?? Have tried disconnecting all components, and unplugging TV and plugging back in. Still will not stay powered on.

    We have the same problem. The TV just went off and when you press power the light comes on for a few seconds and then clicks off. We can't turn the set on with the remote either.

    We've had the same problem with our TV. We'd be watching tv and then it just went out on it's own. My husband changed some connections and it seemed to be working o.k. for about a week. However, this morning it went out again and now the green light won't even go on. I hope someone can help with this problem.

Same issue - our successful fix, at least temporarily, is to unplug power cable from outlet for at LEAST 4 hours...pref. overnight.

TV will not turn on


Hi, It could well be the power supply that is in the back of your set. Have a repairman check it out. It's not a do it yourself thing. Good luck.

I have a rear projection Mitsubishi VS-70803 and fixed it with the help of eagle338 it was working fine for a year and a half. So new issue is I was watching TV and all the sudden i hear a faint spark


The set MAY have the self check feature.

If the set is plugged in and you turn it on and a few seconds later the power light goes off:

On front of set press and hold both the menu and input (device on some) buttons at same time for at least 5 seconds and release both.

Power light should then blink a two digit error code like 2 blinks, 2 blinks a pause and repeat the error for a total of 5 times.

If you get an error code let me know what it is.

Our Mitsubishi projection tv went out one day. When we went to turn it back on all it does is blink the green light for a few seconds and then shuts off. What could it be? Where can we look to see where...


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device"(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 protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE 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--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix.

Please try to reset your internal codes first by pressing and holding the power button for 15 seconds. Watch the lights on the tv set and record how many times they turn green and red.

I have a mitsubishi 1080 series tv. I turned the tv off and then I went to go turn it on, now the little green light on the tv stays on for 2 sec. and then goes away without the piture ever coming on.


A hint--if the green power light comes on for a few moments and goes off do the self check this set has.

On the front of the set press and hold BOTH THE MENU AND INPUT (OR DEVICE) BUTTONS BOTH FOR AT LEAST 5 SECONDS. Release both buttons and look at the power button.

If this is the case the power light will blink a two digit error code--most common in this case is 2 blinks, a pause and 2 blinks--it will repeat the code up to ten times.

Let me know if you find an error code or the power light just blinks and never stops.

If this helped you rate this solution as I do this here for free.

Sony KDF-46E2000 - Screen Goes Blank


You definitely have a bad lamp. Sony rates the lamp life at between 4000 and 8000 hours. There are 3 things that effect the lamp life, listed in order of importance:
1) number of times the lamp is turned on and off. Every time the lamp is first fired, it takes life off the lamp. Customers I see that turn the TV on in the morning, leave it on all day and then turn it off on the evening can get up to 12000 lamp hours
2) ventilation. Be sure you have at least 6 inches of open space all the way around the set and that the vents are clear of dust and debris.
3) power. If the power is interrupted when the set is on, there cannot be a proper cool down cycle. The fans will run after you turn the set off to properly cool it down, if the power is lost this cannot happen. If your power is unreliable, buy a small UPS to let the set finish a cool down cycle

Occasionally a lamp will faill before the average lamp time due to being defective. from your purchase date it sounds like you got about average lamp time. Be sure to purchase AN ORIGINAL SONY LAMP as a replacement, becuase the aftermarket lamps are bad news, Be sure to rate this solution. Thanks!
