Tip & How-To about Sony Grand WEGA KDF-42WE655 42" Rear Projection HDTV

Pix shuts off, green light starts flashing, pix comes back and shuts off again

If you have an issue where your picture turns off and the green power light starts flashing, you are most likely looking at a weak or old lamp. Do not be confused with a pix loss and a RED light flashing, as this can be caused by many things. The normal sequence of events for this fix is this:
1) TV turns on normally, plays for 1 to 3 minutes (may be more or less time)
2) Picture goes out and green power light begins flashing. It may flash for up to 2 minutes
3) green light turns on solid (stops flashing) and picture returns.
4) Picture goes out again and process repeats.

You may have been told that "if the lamp light isn't on, it isn't a bad lamp".
FALSE!
A weak lamp will cause the process above to occur. Other signs of a weak lamp:
The reflector in the lamp is very cloudy
You may see a "growth" or "bubble" on the vertical glass tube which is the lamp
You haven't replaced the lamp in quite some time or it is the original lamp from when you purchased the TV.

In cases like these, try a new lamp. Stick with an original Sony lamp, as there are many stories (both personally witnessed by me and also documented on the web) about problems with after market replacement lamps. And remember, lamps DO NOT have a shelf life; you can store them in a good environment (not too hot or cold!) for an indefinite period with no ill effects.

i have a model 52HM95 installed new bulb worked for awhile 2days when i turned it back on got sound no picture then it kept turning on and off now all i get is the green and red lights flashing on and off


It looks like you have a weak ballast issue this is a common problem with DLP sets, this ballast board starts to wear out with time and use the lamp needs at least 150w 12vdc to turn on and if your ballast board only feeds it 120w or 130w it will not be able to turn on another thing that this ballast due is gather enough energy ( 150w ) to turn on the lamp then get weak again( 120w ) and can't maintain the lamp on and turn back off

Sony bravia KDF-E50A12U rear projecion tv wont turn on


Hi it sounds like it could be an issue with board that powers the lamp ,it's called the ballast.When you put a new lamp in the ballast has to provide more power ,when it starts to go weak it will not light up.Sometimes you can put your old lamp in and will work fine.Try partstore.com they might have it right there.Hvae a blessed one!

lost picture and sound


You likely have a bad lamp. The symptom you describe matches a weak or old lamp. When you first turn on the TV, the lamp is cold and doesn't draw much power. But old lamps usually have clouded reflectors, so the reflector doesn't reflect the light, it converts it into heat. The bulb overheats, draws more current than allowed, the TV "recycles", green light flashing and then the process starts over. Replace the lamp, use and original Sony lamp as the aftermarket lamps are known troublemakers. Please be sure to rate this solution. Thanks!
