SOURCE: TV shuts down

Remove the lamp assembly, There will be a screen on the top and bottom of the assy remove all dust from these screens. also check the tube at the top of of the lamp receptical this is an air cooling pathway. reassemble and fire it up. This worked for me and saved some serious coin judging from some of the other solutions I have seen (lamp and balast) ouch!!!

SOURCE: light blinks 8 times

I did a last minute search to do the repair myself before I called somebody. I found this and figured "This will never work!"
I followed his suggestion and now my TV looks better than it has in months!!! I'M SO RELIEVED!!!! Although I really want to upgrade to a flat screen LCD or PLASMA but I'm not ready for the expensive. I have had this SONY for about 6 years!!
THANKS TVDUDE!!!

SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

Perhaps it needs the bulb, but there is also a good possibility that the lamp fan is getting clogged and shutting down the set. This is NOT the fan you see in the back, instead, it is above the lamp, and is a small blower-type fan, that tends to clog with dust. You CAN check this, when you open the lamp door,you can see the blower wheel, and if it is all dusty, it needs to be cleaned out--but do NOT just blow it out, or you might clog the engine!! It needs to be removed, and cleaned out of the set.

But first...if the blower is not too dirty...try another lamp.

SOURCE: Picture & sound go on & off every sec, red light blinks 5 times

helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Screen went black. Shut t.v. off and tried to turn it back on. Power comes on, front light is green, and in about 3 seconds the t.v. shuts off, green light goes off. Was playing dvd at the time. Shut off...


MOST OF THESE SETS HAVE A SELF DIAGNOSTIC:

UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ONFOR A MOMENT AND GOES OFF.

PRESS AND HOLD "device" and "menu"buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protectthe Convergence IC or IC's is blown---set will detect no voltage to convergenceIC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES ANDTHEN TO GET IT TO REPEAT MORE YOUHAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

let me know what you find--hope that you find 2 blinks, a pause and twoblinks--this is the most common and easiest to fix. SD TECH

Screen turns green The picture and sound are fine when I turn on the tv. After about thirty seconds the screen turns green and then turns off and the power light blinks.


Sad to say, but that's one of the ways a picture tube can behave when it's gone bad. After it warms up, one of the wire elements in the neck of tube sags and touches something it shouldn't. As a result you're seeing the green screen, and then the set shuts down for safety because of voltage feeding back. The only way to repair the set would be with a new tube, and that's completely uneconomical. You can buy a new 32-inch LCD set now for less than the price of a new tube, not including the labor to install the replacement and get the color alignment (convergence) set up.
