DO A HARD RESET: Unplug the power cord for 4 hours. This will discharge all the voltages on the internal eproms. When you power it back up the factory defaults will automatically replace the eprom data. This will correct any corrupted codes.

Of course, this may not be the problem, but could be. So this is a first line check.

WHACKING TEST: Many times these sort of mysterious conditions are a result of loose wiring or cold solder joints. About half of the strange complaints I get fall into this category. While the set is on and while you are trying to address the OSD, bang on the cabinet in several places with your hand or fist. This will jar the set hard enough to restore the faulty internal connection that may have been the culprit.

If nothing pops up by now, it is most likely the controller IC and/or screen graphics driver is defective and needs replaced. This is not related to the picture or video that comes from the program, they are really quite separate.

The cost of this repair could be quite high because it will require a tech to do some clever analysis in order to find out exactly which circuit is the offending one.

I don't think you will find this kind of problem written up in any of the manuals or service books. It is quite strange and really, if a tech is needed, well require one who is a cut above the ordnary one: Someone who really knows how to troubleshoot and analyse and think about what is going on inside. Most Mitsubishi techs are "phone jockeys" the merely call an 800 number and someone tells them which board to replace. They replace until the repair is made and they don't really know what is going on inside - but you get a bill for $400 or $500!

Dont forget to rate me as fixya..

Projection tv no picture has sound no picture

Try resoldering the vertical output IC. The crts may be blanking due to vertical deflection dropping out.

Philips 43PP8545

You have no high voltage, like many in this forum, this model of Philips has some of the same problems. Look around here you may find the answer to your set. If not check Vertical IC, TDA8177, audio ic on signal board up front on left. check Power supply first for blown fuse, 1000, 2004, 1300, 1900 etc. No sound or pic means something is open. Does set has L E D lights on front of set?
