Re: rca p56927 colors out of line
It's most likely a failure of the convergence amp and some other power supply problem in the convergence circuit by the sounds of it... Your unit takes an STK730-130 and some 750k 1/4w resistors for the yoke return. I would bet two or more of them are out of value, at least R19702 and R19703... There are also two diodes Cr19710 and Cr19709. P/N# 164590 which commonly open under a load and are recommended to replace anytime the convergence amp is replaced. Also check Q19700 (Bc457) which crosses nicely to an NTE123a... Not real expensive in a reputable shop - just a pain this time of the year.. I would recommend getting it repaired, it's worth it..

It sounds like your screen might be going bad. Normally there is no setting you need to be doing to adjust colors on your screen. There are some settings when you click Start/Control Panel/Display to look at your display settings, but these normally just control the color around the windows. For example the normal or default color for the strip that is at the top of your internet browser is blue but you can change it. I would say that when you boot your machine if the colors are not what they should be normally during the boot process, then your screen is going bad. You might try Opening a Word Document then type words such as Black, Red, Green, Blue, Yellow, etc. on different lines in the document. Then highlight the word and change the font color to match the word. This might let you see if your colors are true colors or if the screen is bad.
It seems to be that your dmd board might be going out, let's do this go to the menu and if you still have those colors, definitely your dmd board is taking its last breath :P but if they're not there, the issue is going to be with your video board
This is a convergence oroblem. First question is do you have the convergence option in under setup in the customer main menu?... if you dont you may have the very common fl231 fuse problem; i have wrote a article on this under the tips and tricks section. this is a very simple inexpesive repair. If you do have the "convergence option" then you may have to replace one of three cuircit boards
Hi,sounds like the convergence power supply reg.has failed,when this ic fails the adj. projection tv leaves the menu,this ic is located on the board above the board with 6 heat sinks on it mounted on the black plastic,its the ic that is heawt sinked on this board,part number is 215530
