Kp48s35 sony - picture blinks on and off every 2 seconds or so

I have a KP-48S35 sony, the tv turns on, the audio stays steady, but the picture blinks on and off every 2 seconds... It also looks like the green may be "overdriving" the picture because whenever the screen should be black, it is green.

here is a video:

    OK sorry, scratch that, no error codes on this model. You can try accessing the focus block and adjusting the screen voltage down. On most of the sonys it's behind the front cover. You remove the front cover and there's an access board covering the opening where the focus block is located. There are 6 adjustments, 3 for focus and 3 for screens, labelled R G and B. I would try rotating the G screen adjustment counter clockwise.

    Wow, I must say having a video of the problem is above and beyond. A couple of things:
    The green you are seeing when you should have a black screen indicates a white balance problem, meaning that the screens and drives need to be set up properly on the set. Shouldn't be affected the flashing pic problem you are having.
    Here's what I'd like you to do. Turn the set off. Then , using the original remote control, press DISPLAY 5 (the number 5 on the keypad) VOL+ (or volume up) and POWER. Read the screen and tell me if you have any shutdown errors you have displayed (they will be indicated by a 1 as opposed to a 0. That might give me a clue as to what's going on. It COULD be related to the green screen, but normally, if you have the drives adjusted too high, the TV will shut down and flash an error code.

Couldn't see them, but if they were black, or distorted, or strange colors, read on. If your pictures looked strange, it's probably due to a defective CCD imager. If so, Sony should fix this for you for free under their recall advisory, including free shipping both ways. This is regardless of your camera's warranty status. Please check the following link for more info:

SOURCE: KDF-E60A20 Going on and off by blinking lights

it works!! First i took off the front panel. Just check your manual for instructions, very easy to do. If you do not have a manual just down load one from google.. The instruction are easy to follow. The screw they have you loosen with a alan wrench is attached to the plastic, so you do not have to worry about dropping it inside the tv. Removing the lamp was simple. once out you will notice on either side are two small mesh screens. One of mine was 80% blocked with dust, the other side was only 30-40% covered. I used a vacuum to remove the blockage, i did not want the dust and dirt to go inside the bulb. i then cleaned all around the lamp. Reinstalled, and we are go to go. The kids are happy and i am happier since my wife not be buying a new TV.
total cost of repair $.00
time required to fix, less than 15 minutes.

Also when my TV was loosing sound and picture and then return. I did turn off my TV, then turned on. I nothiced a red blinking light. Mine flashed 5 times. After some reserch, 5 times is video related, bulb or video board. google red flashing light with the model you have and you will find what all the codes mean.
So if yours is flashing 5 times try the above, it might work for you and it is well worth the time before you call a tech and drops hundreds of dollars.

hope this helps.

Sony kp48s35 (rear projection tv)

You need to have the crt px tubes checked for heater to cathode shorts, a picture tube restorer is needed to refurbish one or all three tubes to restore balance to tubes. Sony has a px muting built into the circuitry to save the tubes from being destroyed. If one tube is conducting more than one of the other two the imbalance is detected and causes picture (px) muting... blinking on & off the picture. Most repair shops have this crt restorer on hand.
