Check the "screen" control on the flyback (lower knob) its easy to hit moving a board around. Try to adjust back to its original setting. Look for where the dust is, it should be on top. Or any marks might help. Other wise adjust slowly, back off if any retrace lines appear, with user settings at there normal settings.

Mitsubishi TV 65 inch rear projection. WS 65809 I went thru the convergence ic chip replacement years ago. Love the TV. My problem now is that the brightness goes from full bright to full dim then...


The old Mitsubishi units had a super capacitor in the logic circuit instead of a backup battery. This capacitor became leaky over time, causing the problem you describe among others. Number one symptom is set has audio and dark or black picture when powered up. As the super cap charges to full voltage, picture comes and goes.

JVC tv sound but no picture


It could be a main board, but it could be a backlight problem. To verify this, turn on the set, dim the lights in the room, shine a bright flashlight on the screen. If you see a faint picture, you have a backlight problem.

No picture


A very dim picture in this case may be damage to the power supply of the set---If a LCD set it may use back lights of some type--if not on or at full brightness the picture will be very dark.

If I was looking at this set I would open and check to see if voltage for the back lights is correct first.

If decide to do yourself, ya only have to do the green and blue ones, the red light spectrum won't allow fungal growth. Pull whole CRT assembly out to prevent spilled/leaking glycol from onto lower main boards
