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.

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.
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..
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.
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.
