This is one of a group of sets that had BAD picture tubes--all of them.


At one point the tubes were all being replaced under warranty for the first two years. Now the tubes are only available on a rebuild basis and very expensive--defective one has to be removed and sent out for this.

If the set goes bright red in your case it is the red tube and the set is shutting down as the set detects way too much current is being drawn by this.

There is a way to TRY to adjust to compensate for this that requires no replacing of any parts. Essentially what it involves is getting at the point of adjustment from the front of the set.

If you are interested in the instructions reply to this posting and I will be happy to post them here for you----no soldering or replacement of parts is involved and you will know in fifteen minutes if it will help you or not.

I have been fixing sets for well over 30 years and have done this adjustment several times---it may if it works just buy you some more life out of the set as ALL three tubes eventually have this trouble.


Let me know if you want the instructions and I will provide them here.

The picture is is now in pink


If Sony KP-51ws510 it is an common issue with the picture tubes but there may be a simple way to adjust something in the set to correct this--these had problems with the 3 picture tubes where it can go to excessive red, green or blue.

Confirm model and issue and I will assist.

It only requires a screwdriver and the back does not have to be removed in this case.

Sony KP-51WS500: This TV comes on for a few seconds of picture and sound. Then the picture fades to green and then turns off within another 10 seconds. Is this a power supply problem? Or should I look in...


Adjust the Green screen drive,turn it down and see if that corrects the problem.
Remove the Front Bottom Panel on front of Tv and behind it will be the Screen/Focus Control block
It will have 3 controls on Top for Focus to each Tube R/G/B
and under them are the Screen drive controls for R/G/B.
But if adjusting the Green Screen Drive Control does not Fiox It ,then you have a Bad Green Tube.

KP-51WS510 blinking light but no picture at all. Audible click like usual followed by another click sound shortly after.


THE click is the relay on the power board coming on and then going off---red power light should blink a error code---when set shuts off (second click) watch the power light and count the blinks.


Let me know what you find.

Screen turns red then shuts off


Sounds like a bad red projection tube, disconnect red tube socket and try again if tv stays on reconnect tube soket and adjust screen controls on front of tv under the front panel which you will have to remove to do any of this. There are six adjustment controls 3 are for focus for each color and 3 screen controls for each color. Look close at the black plastic control module should be labled R G B for focus and R G B for screens. Good Luck!

Red Shadow


UNDER THE FRONT DOOR PRESS THE BOTTOM BUTTON "FLASH FOCUS" AND SEE IF IT FIXES IT. IF NOT AND YOU SEEN RED DOUBLE OF THE IMAGE, THEN THE SET PROBABLY NEEDS THE CONVERGENCE CIRCUIT REPAIRED.

Sony KP-51WS510 Shuts itself off


eight blinks means, "High-voltage error" and the probable cause location listed is, "T8005 is faulty (D board)". T8005 is the fly-back transformer assembly.
