We just got a TV from my uncle today, it's a Mitsubishi WS-55413, rear projection HDTV. He had it set up as a HD, but we don't yet. Not sure if this makes any difference, but now the damn thing won't work. Even on the DVD player. We tried everything imaginable. The only thing we got in the whole process (besides a black screen) was a picture that was so unstable you can't make it out. It jumps around and goes side-to-side. It was working FINE today at his house. ARGH. We tried hooking the damn thing up using both antennas (A & B) and used the input slots. I can't figure out if something happened during the two block commute or if we are complete idiots. The fact that the DVD player does the same thing worries me though. Thanks for your help........Stephanie

Re:
Check this first:1. White raster with no signal, washed out looking video with signal. Access the service menu, "menu 0357" use the audio button to select "video chroma" adjustments, use the video button to select item "40 - AGIW", use the adjust button to change the setting to 0, then press the enter button to store the change/////This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. Shutdown at power with self diagnosis error 2-1. At power on check for 12-volts DC at connector KH pin 8, if missing check IC9C51 part # 270P990010 and L9C52 part # 441D009020 on the Signal PCB

Have the remote tested alone--all shops can do this and if it tests good suspect the remote receiver in the set (usually is dead center behind the screen in the middle above the lens.
There is no "reset" as the set has in the customer and tech menus ways to attempt to manually adjust this.
under convergence in the customer menu select advanced and follow the instructions on the screen.
If Red or Blue or Green are skewed and will not adjust it means one of the two STK-394-250 CONVERGENCE chips this set uses is bad.
Depending on where you buy them they will range in price from about 12 dollars each to nearly 35 dollars each.
Let me know what you find; this may or may not be a do it yourself repair as some real expertise is required to correctly get at and replace the chips.
Howdy,
The control buttons may be getting stuck. Try this:
1. Remove front speaker grill
2. Disconnect the two cables that are sticking out of the top of the inner cover. The TV will still work with remote. If that helps replace switches, control board not available. Part Number 432P109010 quanity 9.
First check for the coolant/fluid leakage from the picture tube on to the signal board. Wipe it with paper towel and dry it will the hair dryer. I hope there's no corrosion yet.
you have some caps that have failed in the dm module
that will have to be replaced to correct the problem
if your know how to change them and have the tools the caps can be obtained through most electroinc parts suppliers
there 1000mfd 16v we increase working voltage to 35WV
if you can change them let me know and i can give you locations on the board and the dm stands on the right side of chassis at rear
