Good Day, den005;

Sounds like you a CRT drive problem. Does screen change when attempt to adjust the G2 voltage?
Your 1995 TV has served you well and I think it would be a waste of $'s to attempt to repair. Buy a new LCD, HD TV. FEB. 2009 is just around the corner (for HD only signal).
It sounds like CRT (picture tube) may be bad.

Good Luck, big IRISH.

Video went blank


It may be. I have replaced the lamp in my sony 3 times. Look for dlp lamps online and enter in your tv model. There are instructions online on how to change it yourself. They also show you in your manual. The power light should blink red indicating bulb failure. Read your manual. Hope that helps

Mitshubishi VS-6041 No picture, sound ok


It has been my experience with that model mitsubishi that the usual culprit is loss of vertical sweep. If the beams in the picture tubes stops moving up and down this is detected by the micro processor and the video is blanked, but the set is not shut down. The usual cause of loss of vertical sweep is bad solder connections on the deflection yokes or a failed vertical output IC.

Mitsubishi TV had horizontal lines across the screen and rolls up


Answer
ONE: Yes, the speaker mounted close/near to the set can be a cause of mischief; please move it further away and see if that helps clear up the problem. But, you must keep it away for several days before you will know for sure because it takes some time to degauss all the internal parts that may have become corrupted by the magnets in the speaker.

TWO: Yes, any set can be repaired the question is cost and wisdom. Old sets are sometimes not worthy of the repair simply because of the likelyhood that another failure will follow soon after. A big screen always invokes a repair charge of $200 and up. After a few of these you will wish you had put all the money into a new set!

THREE: The lines are most likely a problem in the vertical blanking circuits of the set. These are horizontal retrace lines that are supposed to be blanked out during vertical retrace of the raster. Think of it as a paintbrush that scans across the screen painting thin lines and when you get to the bottom of the screen it goes quickly back to the top, but during that time the horizontal, which is many times faster, has made several sweeps; so it must be blanked out during the retrace. The repair involves finding the guilty parts and replacing them. Usually this repair runs over the $200 somewhat.

FOUR: Prior to calling in a service tech try a hard reset to see if that will recover any of the circuit degradations. Merely unplug the power cord and leave unplugged for 4 hours or more. It may help. Or, it may not help; but worth a try since is won't cost you anything.

If the set is over 5 or 6 years of age it probably is not a condidate for any expensive repair. On the other hand, it is a Toshiba - and they make a fine set.

Hope this helps. Let me know if you have further thoughts.

Screen went blank sound ok


Do yo have the remote? Do you have the manual? Manuals are usually available online.
If you are feeding the Toshiba with cable wiring then the problem is with the Toshiba. Maybe something as simple as the wrong input is selected on the remote control. If you are feeding the Toshiba with audio and video cables then the input to the Toshiba would be suspect. Either cabling (the inputs and outputs are plugged in wrong. If you changed anything I would retrace your steps.

Let me know by clicking on 'ask me' and if solved please do the rating. Thanks.

MITSUBISHI 65" WIDESCREEN MODEL WS 65809 (GREEN GONE, SMALL RED LINES)


in the front cover turn up screens on all colors till you see retrace lines, then back them down to where dissappear. enless you know the correct voltage to set it. as for the green. i would try the red crt on the green and see if it looks ok. if so then replace crt circuit or check transistors on crt circuit may also need to change the driver on the heat sync.
