    I have a Pioneer SD 533HD5, The TV does not turn off. The picture is perfect other than it is pink...I took the back cover off and found what I had suspected. The Green light was flickering and going off then on again. Sometimes it stays on for days, weeks, months then it will shut off and we are stuck with a pink/red TV screen...Is this a connection problem somewhere? If so where do I start. I don't think it's convergence or the other colors would be distorted. Any help?

Turns on for 30 sec then goes bright blue and goes back into standby. turn back on it does it agian


This is blue CRT problem in tv as it is rear projection tv that has three CRTs red-green-blue inside to project color picture on front screen.
Blue CRT (tube) will be replaced to fix the issue and it is job of Pro because lots of adjustments are required after replacement of tube.
Local tv repair shop will help you for that.
Thanks

Red arching lines showing up on screen promident when a dark background is present


Red picture tube needs screen voltage adjust. Open fornt or back of TV and look for a black square looking box with adjustment knobs. Look for red screen adj and slowly turn rt or lft until lines just disappear. If screen goes too bright tv will shut down, just turn back on again and retry

one way to tell turn the red screen control counter clockwise and see if you can control the tube gain
and then you can lightly tap on crt neck and i do mean carfuly and see if it flashes it most likely will and you would need to change the crt and reset it up

The tv is showing red lines on the screen.


These are retrace lines. The screen on the red tube is turned up too high. Inside the set there are 6 knobs. 3 for focus & 3 for screen. Turn down the red screen until lines are gone. These knobs are usually found by pulling of the front panel.

The color suddenly turns red for few minutes then goes back normal and goes back and forth intermittently on my hitachi 57f500 tv.


Hello edgarhelen1,

This could be a problem with the Red tube (Grid to Cathode short). I would suggest that you have the tube checked. However if you have a CRT tester you could do this yourself. I any event this sounds like a CRT issue.

After 5 minutes of good use screen goes redish color


It certainly sounds like the Red CRT (picture tube) has heater-cathode leakage and is not likely worth repairing, as all 3 tubes usually have to be replaced at the same time for best picture quality.
