So after six weeks in the shop, the TV is beyond repair. The part to fix the pixilating problem finally came in, but the picture continued to get worse throughout their testing week. They tried repairing the motherboard, or what have you, and were unsuccessful. There is now NO VIDEO at all. They suggested packaging it up and sending it back to Westinghouse, a previous customer was charged a $350 flat fee to repair it. I would rather scrap it. Why spend that much more on a TV that has proven to be a problem child. Screw it! I'm getting a LG!
As stated before this seems to be associated with the overheating of some component. On
my set I need to check that the backlight is set to a low level. On power up it automatically adjusts to a level above maximum and the green
screen will appear in a few minutes. I took the back off to increase airflow and that
helped some. Now the problem only occurs rarely.
Without a fan on sitting directly behind, it'll only take about 15 minutes before the screen bugs. Not to mention, the televison generates heat when off, so uplugging when not under use helps. Other than that, i'm trading it back in through Westinghouse for another one. Hopefully its not problematic or the overall product is definately trash.

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.
There's nothing wrong. The blinking areas are blown-out highlights. These are the portions of your picture that the camera thinks are overexposed. While viewing the picture, press cursor-up/down to cycle through the different views of your picture.
Zenith was very well known for having bad pix tubes...and it was usually the green gun that was affected...there is a place in Illinois that carries the zenith line of replacement parts ... the website is www.ued.net and the name of the co. is Union Electronic Distributors....you may need to go to the website and get their ph # to talk to a rep....you will need the model no and serial no of the set to get a replacement tube...a word of caution though...pix tubes are very expensive ,,,,so dont be alarmed if it costs 500.00 or more
you need ssb board is bad and you can,t git that part you can send to pts to have it rebuld. yes the stk 392-120 can drag the pix down but if you open it up you see a fouc blook go to the screen red or green or blue turn it up just a litte the pix will come back. this is a know fact about this with this set i see a lot in my days of sevice ,at quaker tv
Possible green CRT bad....remove lower front speaker cover
and access panel.......carefully disconnect green PC board
from green CRT ( center tube )....plug in TV..power set....should have steady red/blue pix (no green) = bad green CRT............T.
