Question about Mitsubishi VS-5043 50" Rear Projection Television

1 Answer

No Picture after it's been on a while. Audio OK.

Performs very well for a while (say 1-2hrs) then screen goes black (a thin red,green blue line shrinks to a pinpoint in about 1-2secs then only sound. Audio plays well. If I turn it off for 15-20 minutes it's fine. Seems more frequent the warmer the ambient room temp. Also I have a convergence problem that I can "fix" with a light tap (no kidding "light tap") to the side. The convergence problem goes away the longer the set has been on (say 20-30 minutes).

Re: No Picture after it's been on a while. Audio OK.

Ok you have a vert sweep problem and yes its probably connected to in a way to the "tap and fix" problem! Seems to be n intermittant connection on the vertical out put Ic or maybe even on the rgb convergence ic?? The total loss of sweep though tells me that theres two differant problems! Maybe and intemittant connection on the vert output Ic as well as bad connections on the convergence ic??.

Black and white picture with red lines vibrating with sound.

More info would be nice. Are you using HDMI or Component cables. If it is component cables (red, blue, green for video white and red for audio) Check your red and blue connection. Green alone will give you a black and white picture.
If you are using an HDMI cable, replace the cable to see if this changes anything or if you have another tv swap cables to see if problem stays with tv or moves to another tv.

Why does my tv have one blue, one red and one green line at the top of the screen but no picture?

The CRT inside the TV has gone bad. You can either find the make and model of the CRT and replace it, or get rid of the tv and buy another one.

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....

Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

There is just three lines that show red, green and blue.

It has been my experience with Sonys that those three colored lines indicate that the set is having trouble with the data communication lines. The hitch is that a model as complex as that one has as many as five seperate clock/data lines and if any one of them goes down the set will exhibit your symptom. It will take a professional to track down which line is causing the problem. I've seen audio output IC's as well as tuners cause the problem.

Lines on the screen

Are they thin, white lines running east to west? If so, they are called retrace lines and indicate that the screen settings for the picture tubes is set too high or there may be a mal-function of the CRT driver circuitry. Try adjusting the screen controls which are located behind the front grill of the TV behind an access panel. Once you remove the grill and access panel, you'll see a small control assembly the has two sets of controls. Three for adjusting the red, green, and blue focus, the other, the red, blue, and green screen controls. To adjust correctly, put the TV on an unused input(dark, blank picture) and adjust until there are no visable retrace lines or color in the image.
