Question about Mitsubishi WT-46807 46" Rear Projection Television

1 Answer

Rainbow line will come across screen and then goes blank. This is an intermittent problem. Normally if I turn it off and back on, it works. Now it does not.

My TV will be playing, then all of the sudden a multicolored horizontal line will appear and the screen will go blank. It is almost like it is overheating or something. It has been doing this intermittently for a month or two. Normally, I can turn the TV off and back on and it is back to normal. Right now, that is not working. Please help.

Try resoldering the vertical output IC, the IC runs at a hot temperature and this can cause the Pins to have cracked solder.

Horizontal lines appear on 32" in some hd format movies.


The technician is right, the TV will not show such lines selectively. Try changing the input device to some other. Play some sure shot, genuine DVD.

Lines down screen


We have a Samsung LE32A457, whilst we were watching T.V tonight the top halve of the screen suddenly appeared with green lines halfway down the screen and that half of the picture was unwatchable, T.V is 2 years old. We have removed all scart leads but this did not help and the problem still exists, when shutting down a white horizontal line across the centre of the screen appears from this line upwards the picture is faulty. Any help or advice would be grateful.

The image disappears on my tv screen. A horizontal line appears.


You need to check the horizontal IC for deffects, possibly and most likely there are dry joints on the legs of the Horizontal IC. Have all the legs on the IC soldered nicely, this shud sort out your problems as you say you hit the TV then works. Try this before replacing the IC

First you want to determine if the issue affects the tv's menu if it does you are looking at a Light Engine issue which is expensive if it does not interfere with the On Screen Display the issue is with your signal board, also check to see if this happens on multiple inputs with multiple signal sources if it doesn't you just might want to use a different input which is a way cheaper solution

This should be repairable. It may be the LVDS Cable or the Main board problem. The only other problem is the T-Con Board.

Horizontal multicolored lines appearing


Open up the TV and unplug and re-plug the connectors to the circuit boards. This is most often caused by a poor connection of the circuit board connectors.
