    I have has trace lines for about a year now, the scrn has recently went all green and is going into standby mode every 30 secs or so. Are all of these problems related? I read on how to adjust the POT - in the front o fthe set under the grill for the trace lines, where are the tubes located & accessed from?

The green crt is most likely shorted. thats fairly common with that chassis.

My sony kp-51ws500 tv screen would turn green and stay on for about 30 sec, then trun off. I adjusted the green screen button on the black box in the front of the tv....via info from this site. It fix the...


Doing the adjustment is not actually a fix, all that does is change the drive amount of the green CRT which allows the set to work but the 3 CRts will be out of balance so picture color will be affected. The only way to repair a bad CRT is to replace the CRT itself. You can get replacement Green CRT from www.tvrepairworld.com

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.

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!

Turns off after 30 seconds


i think the convergence amps are weak, or the akb circut has caused the tubes to go bad, google your model number to see if it is in the tube problem. sony made some projos w/ bad tubes in them. tv lasts only three or four years,no cause i had one

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sony kp-57ws500 green screen then auto shutoff


I have the same tv and it did the same thing only now it has red hues all around the picture as well. The service guy told me it was the green tube and it would be about $500.00 to replace and may not fix the problem. What a p.o.s. I will not be guilty of buying any other Sony products from now on.
