Sony 52" rear projection tc

Having problems with my 7 year old, just the last week, will lose picture and sound, standby blinks 5 times then stops and then blinks four times over and over. Picture will usually come back after shut off, then repeat the black screen again until turned off (and so on, you get the idea). Funny enough friend bought the exact same sony 52" tv 3 months after myself and is experiencing same problems. Any help appreciated.....Thanxs the tv goes off after doing this sequence. and it blinks 5x's

5 blinks means problem in the AKB (video) and 4 blinks means problem with the verticle deflection. Try this to get the screen to display any recent faults then get back to me and let me know what it said. Press the following buttons on the remote.
Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up
a screen with a list of the problems and number of times they have occurred.
Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC.
We have repeated them in parentheses in the text for the "Blinks" described
above so you can correlate between the diagnostic screen and the blink
codes.

Hi there,
5 blinks means there is a problem with the video board. It could be as simple as unplugging everything, includding power. Wait 3 minutes then plug power only back in. Or it may be a damaged component that requires replacing.
Hope this helps

5 times blinks is error code for No Good White Balance and you said that picture is very green.
As you know TV is approx 7 years old so it needs RGB gain adjustments.
If you are TV tech person or know about TV repair, let me know to guide you further. Or contact local TV repair shop to fix it.

Based on service manual info, it cant blinks 7 times as per symptoms, please count again blinks. It can be 5 times.
If its 7 times blink, Horizontal Deflection stopped in this case. If you want to repair it at your own, please let me know to guide you further but it is necessary you should have knowledge of electronics.

its not the time for new tv yet.as the problem you r facing is not a major problem.

Check for multiple poor solder connection on the sweep/power supply board.

just need to balance the three colors red,green and blue that may help. remove the front covers and look for black module that have screw and focus controls just move little bit left or rightbe carefull because you can loos the picture
