Question about Mitsubishi WS-55313 55" Rear Projection HDTV-Ready Television

1 Answer

Lines horizonal - seems to be caused by voltage to green CRT

If you give the green CRT any voltage at all... red to blue lines appear depending on the settings of the other two CRTs...You have to turn the voltage regulator completely off to eliminate the lines.. leaving a distorted blue/red picture... There is also a humming noise when voltage is turned on to green CRT...

Your green CRT is shorted. To test put your red crt socket on the green and your red on the green. then try turning up red control if the green now works its not your tube. If the same thing happens with the red socket on the green you can be sure its the green CRT if the green works properly with the red socket, then you have a problem in the green drive circuit and not the CRT. hope this helps.

After having our tv in storage for aver a year, now it has a green shadow to it. What could be wrong/

Not sure I understand what you mean by green shadow. I would check the fluid in the green and blue CRTS and verify they are clear. I would do this if the green color seemed fuzzy or blotchy looking on the screen.

When looking on a blank screen, do you see any arc lines of either green, blue or red? If so, you would need to lower the screen voltage for that particular CRT.

There is just three lines that show red, green and blue.

It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

Sony KP65WS500 5 blinks

I think problem is in Protection circuit itself. Protection seems unstable in your tv that's why it doesn't give you chance to diagnose problem.
Try to isolate protection command and check tv.
Its an idea and hopefully it will work.

I got this Sony KP-57WS500 57 in TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE.
