The Sony diagnostic routine for 4 blinks indicates it to be a vertical deflection problem.

Did you see a solid horizontal line in the center of the screen prior to it going out? If so, that is a tell tale sign for vertical problems.

basic sony reset below

The STANDBY light will flash if the television detects an issue within the television. Some of these issues can be resolved simply by following the steps below to reset the television.

  1. Turn off the television. IMPORTANT: For a projection television that uses an internal lamp, wait 5 minutes after turning off the television to allow the lamp to cool before continuing with the following steps.
  2. Unplug the television power cord from the electrical outlet.
  3. Let the television remain without power for 60 seconds.
  4. Plug the power cord back into the electrical outlet. NOTE: If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
  5. Turn on the television.

If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center

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".
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.

Wont power on

Sounds like you need a new bulb, or possibly new lamp. The red/green flashing is the warm up to get the bulb ready. If it's shutting down after that, instead of turning on, it means the bulb isn't working - that's a common thing, for the bulb to burn out. Possibly the lamp's bad, but that's much less likely.

Trying to replace lamp in HDTV and having trouble. Does not function correctly after putting in new bulb. Boots up and then visuals go black and the green power light keeps flashing. Help?

Panasonic DLP TV Bulbs

Make sure its an original Osram or Philips bulb inside the housing. If its a cheap lamp it will act this way. If it is an original lamp, then you may have a power supply issue. It shouldn't affect your TV but you may want to try resetting the lamp timer by following the instructions that came with the lamp.

While pressing the VOL- button on the projection display, hold down the number 0 button on the remote control at the same time for more than 5 seconds.

TV will not turn on. Red light flashes 4 times

Try connecting the TV directly to a different wall outlet and check. If the issue persists, try power resetting the TV. Turn Off the TV and remove the power plug from the wall outlet for 1 minute and reconnect it and check the operation. If the issue persists, then the TV requires service.
