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...

    Yes, I should have mentioned that I switched up the wires to make sure it wasn't a short in the controls. It disrupts the picture on the green, no matter what control that CRT is hooked into. So what do you do about a shorted out CRT?
    I don't see anything loose or any visible problems whatsoever...Can you buy and replace these things yourself?

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.

I gotta a green screen

It is possible that you have a shorted green CRT, you can remove the front speaker cover, and you will fine a focus block, and if you turn down the green screen voltage, very slowly, the green should turn down. if not then the gun (CRT) will have to be replace, If it does turn down, then go into the menu and turn the color are the way down and that should give you a black and white picture. If it is not black and white. adjust the red, blue, and green screen voltages until you receive a good black and white picture. Turn slowly they are touchy, and if turn to high, you will get retrace lines and the TV will shut down.

I get interferance mainly red and green lines appearing on top of the picture plus crackling noises

Please put off your tv and open the back side of the TV. Look for dirt on the back side of the CRT that is causing the arcing of the high voltage. So when the high voltage is sparking against the ground section the lines are coming to the screen. So use a good dry cloth to clean and wipe clean.Use a good solvent like methy spirit to clean. Check to trial and repeat if the fault is repeating. Make sure the HT lines are not touching but keep them apart to redduce the sparks. Hope this will get the TV right. Good day

Samsung CRT HDTV - Color Problem - Red, Blue, No Green

This will be a lack of green drive caused either by the green output transistor having failed or no green output from the driver IC. As to which you have depends on how old the TV is. These are located on the CRT base (square type board connected to the neck of the CRT. You would need a multimeter to check the voltages going to the green output on the crt. It is also very possible the CRT is internally faulty giving no green, if this is so, you will need the crt (tube) to be replaced,it is not very economical to do this now a days.

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.
