    I am not sure if it is a projection tv. I have known it as a CRT or a glass tube tv. Would that make any difference? I come from Australia, so it may be a difference in common terms.

Sounds like the picture tube is going bad or there is a screen voltage capacitor bad in the sweep power supply.

CONTRAST ADJUSTMENT


it is best to shut the color level to the lowest setting then try t balance the screens to achieve the best black and white picture. then turn up your color level. Your brightness level should also be set to 50 % then when you adjust for the best B&W picture. You will have better color and brightness when you reset your color and brightness levels.

I am further looking into ur problem..

Goodluck..

What makes Whites appear so bright almost blooming that hurt the eyes


In the model listed here having contrast way too high can cause that--contrast should not exceed 70 percent and brightness should be a bit lower or equal--note as contrast is lowered the white smearing should lessen.

Pioneer Elite Pro 620 HD TV on several occasions the screen has gone black but sound continues and the power green libht remains on. After shutting down for 10-15 minutes picture comes back.


Pioneer Elite Pro rear projection 620HD - Picture is still there but brightness and "white" have faded over years allowing for mediocre viewing when room is dark only. During the daylight picture is visible if viewed straight on and within 15 feet from set. Any suggestions?

Mitsubishi VS-6041- picture brightness not very bright


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

No contrast


first turn your color all way off or down.try turning your contrast way down as far as it will go you should see a darker picture. now bring up the brightness to a point half way. bring the contrast up to see grays and whites and blacks...adjust brightness more if need be. now you should see a nice black and white picture. no bring your color up last ...not saturate but to your liking. if you stilll got problems i bet your video out transistor is shorted....meaning shop work.
