I have a 6 year old(nov 04) Sony KV-30HS420 that turns off all by itself. The screen goes to green and the picture fades to black. The sound will keep playing for a few seconds then the TV will turn itself...


If the screen goes rather bright green it is one of two things:

1. It is possible it is a shorted green gun in the picture tube, there are three of them, red, green and blue guns in neck of the tube.

2. The other possible reason is there is a problem on the small circuit board at the end of the picture tube, this model should use three IC chips, one for each red, green and blue.

Being intermittent makes it hard to tell but ask the shop if they tried the self check this set should have. With the set turned off use the original Sony remote and hit Display, 5, vol down, and power.

If the set has a self check (it should) a box will appear on the screen with up to five items with a zero to the right of each, items will be like AKB, OVP, etc, and if any have something other than a zero to the right it pinpoints what happened.

Sets with this feature record each event where something goes wrong, ANYTHING other than a 0 indicates what failure was detected.

If I was to make a guess there will be a number next to AKB, which is Anti-Kine Bias, this means the picture tube or something on the board at the end of it drew too much current and the set's shut down circuit turned the set off.

I actually fixed one of these where both the blue and red IC chips on that board were bad, needless to say, I replaced all three of them.

Any good shop would know about the self check and even if the set did not shut down in the shop the self check would point to the area where the problem is.

Let me know if you need more help or find a error code.

6 horizontal lines


I would look for a Vertical circuit failure. Most likely is the vertical output IC and or open resistor off the hv transformer. Definitely look for any loose solder connections around the Vertical output IC.
Hope this helps,

Sony KV-36FS12 Lost Green


Hi!

Five blinks means - 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.

Please rate this solution as FixYa if found useful.

Thanks

    Five blinks means "Video out abnormality detection". Possible problem areas are as follows:

    Video out, IC7101, 7201, 7301 and others in C board circuit.
    Q510, 516, 524 (A board).

    There are actually three C boards, the CR, CG and CB boards. They are attached to the rear of the red, green and blue CRTs, respectively. I wouldnt attempt to repair the set myself. I would solicite the services of an authorized Sony servicenter.

    Hello im having problems with my sony wega


    It sounds like you have a loss of green. This could be caused by the green gun in the picture tube opening up or the drive circuit for the green gun gone bad. Stargazer
