Samsung Screen Flashes On and Off

My Samsung T629 started flashing the Samsung screen on and off repeatedly today when I went to take a video. I've removed the battery and re-started it but get the same problem. The phone's not turning off, just flashing that screen then going black for a second before flashing the screen again. T-Mobile thinks its water damage (The dot under the battery is 1/6th red. Help!

    Mine is a SGH-U708E and it is doing the same even though it is only a couple of months old. Not good.

SOURCE: TV quits working, screen goes black and red light next to power green light flashes 4 quick flashes.

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

SOURCE: TV turns on for a split second then back to standyby

i think your capacitor is blown, do a google search for insignia, lcd, capacitor...
you can buy another one for about $2 but its a pain to install, you can also instead buy a new powerboard for about $80, its an east install and you wont blow more capacitors

Take your sim car out and try using these codes to reset the phone.

Your phone software could also be corrupt.
If you go to samsung you may be able to update the firmware in the phone over the internet.

If all else fails have the phone re-flashed by a technician.
