My sony wega keeps cutting off then coming back .


a couple of years old can be a long time:

has the TV been on 24\7

It's the amount of hours that matters..

electrolytic capacitors typically last 3000 to 5000 hours....

Special "long life" caps last close to 7000
but the caps in most consumer electronics, even broadcast equipment 3-5K hours.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

Sony Wega 40" TV will not turn on, standby light blinks 6 times repeatedly


Hello,For model KV-40XBR800,

Pls check following area.

Low HV Shutdown:
On the D Board.
Check IC8004/pin 7 should be 7.4v.
Check IC8006/pin 2 should be 2.5v if lower will trigger shutdown by causing pin 1 to turn on.
Check IC8006/pin 3 reference voltage 2.2v.
IC8006/pin 1 normally at 0v. If high
turns D5007 ON which turns the latch circuit Q6532,
Q6530, and Q6527 ON and turns the AC relay RY6501 OFF.

And NOTE: 6 blinks also can be Low B+ protection.

Unregulated 7.5 v from the power supply to 5v reg IC504 on the A Board. 5v to M Board Q2314

to CPU IC2300/pin 43. If 5v missing set will shutdown with 6 blinks.

Good Luck

No image but good quality speaker.


Sony has had a problem in older sets with-believe it or not- lack of humidity. I had one with the same problem. If it is under warentee take it back, if not-I know it sounds insane- put a large plastic garbage bag over the turned off set. Leave it that way for a couple of days. do not turn it on during this time. After a couple of days remove the bag and turn it on. If it works-that's the problem, if it doesn't- it's dying, and to expensive to fix. Surprised the heck outta' me when I tried it on my old Sony 19" set- it worked.

PS3 No signal to the TV


I'm having similar problems. I had my PS3 on pause, whent out for a couple hours, came back to find a weird fuzzy screen. My PS3 had froze, so I turned it off. I turned it on a couple minutes later, and the green light came on, however, my controllers would not connect, no image was popping up and it also wouldnt turn off unless I flicked the switch on the back. After contacting Sony, they told me it could be an overheating issue. If it has been less than a year, they will replace it, NOT FIX IT. Which is great and all, but unfortunately I am about to lose the countless hours I've put into assassins creed, skate, call of duty 4 and motorstorm.

HOWEVER. If your PS3 is still "functioning properly" except for no signal, turn the power off on the back, turn it back on, press and hold the power button on the front untill you hear the second beep, let go, give it a couple seconds, turn it off from the back and then back on, hold it till the second beep again. Good luck.

P.S. I recomend getting the extra cooling fan for it, and saving game data on another card (SD) incase crap like this happens.

TV Turns off and on


How long since the last time the bulb was replaced? It sounds like the bulb is overheating and triggering a safety shutdown.

It's probably in need of nothing more than a good cleaning (open it up, clean off the boards with a can of air) and *may* be time to replace the bulb.
