Mitsubishi VS-6041 TV works fine, but after say 2 days the picture goes black, but sound still works. So we turn it off, unplug it and push aside for a week or so, then pull it back out, plug it in and turn on and it works again. Whats the deal?

You may attempt a B+ replacement. This controls the high frequency voltage that powers all the RGB tubes needed for picture. The B+ flyback looks like this:



Best of luck! Thank you

OK this is going to be either a tube problem or a convergence board problem, either way your going to have to get it serviced, unless your really electric savy and care to take it apart and solder pieces. There is no real fix to your problem without actually going "in"...

Replace Both of your STK ICs example STK394-250 they are big black ics will have part number on them Call Mats 1-800-628-1118 for parts.

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.

LAMP BULB IS BLOWN

Is it only the input that has the direct tv connected to it that has no picture, or do you have no picture at all on any inputs? If you are able to watch a dvd on say AV1 or input 1 but have no picture on the other input that has the direct tv box connected to it I would call direct tv and have them look at your box. If you have no picture at all then it is your tv. and it being 10 years old it is almost a natural failure a strange occurrence that being it happen right after you got satellite.

Hi Dawn,
The TV does have a screen control on each of the picture tubes ( there are 3 ) although I do suggest you have a qualified technician make the necessary adjustments as an improper adjustment can cause damage to the set. Should you deside to make these adjustments yourself, you'll need to remove the back ( or front in some sets) ( PRE-CAUTION, UNPLUG THE SET FROM THE WALL BEFORE PREFORMING ANY ADJUSTMENTS INSIDE THE SET ) The screen adjustments are located either on the bottom of each tube or in a group component located where the main High Voltage Wire ( large red wire from the black transformer on the deflection board ) is connected to. Look for a turn pot ( screw type adjustment ) that is marked SCREEN. When you locate it ( whether it be on each tube or in the group component ) turn it up only slightly and not to much, as excessive gain ( turning it up to much ) may cause the TV to shut down. When you have the proper brightness ( when it looks good to you ) close the set up and enjoy the renewed picture. Good luck and I do hope this has helped in some way

Hello bgill,

At first I thought this was a problem with the bulb, but as I read further into your description of the problem the more it sounded like a control processor issue. The fact that the TV acts normal when the volume control is pressed, indicates that the control processor might be going bad, or at least some of the processor biasing circuitry might be going bad. The circuitry in question is somehow linked to either the bulb control circuitry.

You will have to have a qualified TV technician look at this set to determine what the problem is

I hope this helps,

Thank you,

This happened to me and it turned out the closed captioning on my TV were activated somehow. I never even touch the controls on the TV but I had to manually check the settings on the TV and found that the captions were on.

wondering if you still have this i would like to buy it from you and wher u are locatred
