Question about Mitsubishi WT-46807 46" Rear Projection Television

1 Answer

On bright screens picture goes to white and shakes

The TV used to shake for the first ten minutes or so untill it seemed to warm up. Now, on any bright pictured scene the screen goes whitish and won't go "normal" untill the scene changes into a darker part of the movie. I thank you for your time.

Zenith z56dc1d dlp tv picture works for about 1 minute then starts shaking and tv shuts off


You may want to get it in a rather warm room and or remove rear cover and use a hairdryer to warm everything up inside the Cabinet--with rear cover off look to see if the fans are dirty etc and if they all come on, if a DLP especially look at the lamp itself and the fan that cools it.

When you turn the tv on it goes to the settings screen and you can't get a picture for about 20 minutes until it warms up


Fist is contact Philips to see if this (with the model number) is a known issue or if there is a software upgrade available for this set.

Hi there the problem is, The techwood 42" tv that we have is ok for the first ten minutes. Then after that the tv screen goes white. Then after about another ten minutes the picture is fine.Do you...


Hi, i think there is a loose or bad solder. try to inspect the power board for loose solder or in the area of the inverter board, resoldering some capacitors may electrecute you . leave the set unplugged for an hour before resoldering to allow discharging. you may replace some capacitors that seems slightly become fat..

Screen Shakes on High Resolutions


your rate of refresh is too high, it's refreshing too fast, you need to lower the screen resolution. keep in mind, the tv resolution is much much smaller than a computer monitor. a computer monitor has much higher resolution. so Tv can only handle so much in resolution. if you need a better picture, it always the best to buy a monitor, not a tv for computer to get a good picture. if you have any more questions, let me know.

TV picture shaking!!!


You have a Hyper module problem.Very common with these chassis.Toshiba part # 23148024.This part is no longer available,but it can be repaired.I dont know how much electronics training you may have but it`s a pretty detailed job.The hyper board is the silver stand up module inside the unit right behind the external Audio/Video jack panel.There are 11 little capacitors that all need to be replaced.The value of these caps are 10uf @ 16VDC.I do this job for about $245.00 and the unit works fine.Check with your local shop if it is too much for you.If you don`t know what you are doing you can ruin this module then it`s time for a new set.Good luck.
