Question about Mitsubishi VS-60601 60" Rear Projection Television

1 Answer

Green color lost

While watching my Mitsu 60" (VS-60601) rear projection TV the other night the green color went out on the screen. I have noticed that over the last few weeks there has been an occasional green flicker on the screen or a few seconds where the green went away, but always came back. The picture (less green) is still clear and focused. I got the TV free from a guy that wanted it moved because something dripped on the circuit boards in the bottom of the TV and shorted the leg out on a diode. (He wanted to update to a 103" front projection unit instead of fixing this one) I fixed that with a soldering iron and a new diode, so I'm not afraid to open the TV and do the work, I just don't know where to start. Any help would be GREATLY appreciated and will help to continue the legacy of how I (fortunately) received a great TV. Thanks, Dekeman

    Thank you very much for the input. I haven't 100% addressed the issue yet, but I did wiggle some of the wires on the green CRT board and the color came back. Now I have to figure out exactly which wire it is.

    The only other concern I have is reaching into the TV without getting shocked/shorting something. I know some of these TV's jump the voltage up to ~40-50 kV, do you know if any of that is run at the CRT board or is it all at the top by the lens compartment?

First thing to check my friend is bad connections on the green CRT board, or cannections on the green crt and the socket. If there are no bad connections on the board, but to tell you the truth there most likely is, as I have found this problem many many times in the past, you could take off the green crt board and swap it with one of the other board from the other two crts and the picturew will not be right, but this will tell you if the problem is on the green board or the green driver circuit. if the green continues to go out on this setup, then I would tend to believe that the green CRT is intermittant. Good Luck

The Picture on my Mitsubishi vs-60805 "shrank" then disappeared
it isnt worth it, your verticle diflection is out, that board is about 3-4 hundred, and you would probabily need a service center do it(messing with like 30000 volts)and they will probabily charge around 200

No picture
Sound like you lost Vertical Deflection.  Youshould not have a line across the screen because this could destroy the threeCRT Red, Green, and Blue (Picture tubes) if left on to long. There is a protection circuit built in to protect your CRT’s.    Check on the PCB-SIGNALboard (Tuner located on this board) transistors Q-206 Collector should be around 1 Volt Base and Emitter 0V. If the voltage atthis point is greater then 5 Volts the Vertical output IC-401 (Mounted on heat sink 7 pin inline IC) is bad, Part # LA7845.  Pin Voltages should be PIN 1= 0V, 2= 34V, 3= 32V, 4= 3V, 5= 3V, 6= 33v, 7= -6V.  Data sheet located at http://pdf1.alldatasheet.com/datasheet-pdf/view/40357/SANYO/LA7845.html

My screen is turning colors
May it have been knocked about so the projectors are out of alignment, or may it have been standing next to a powerfull magnetic field?

It may also sound like a mirror may have become misaligned, since the top half is affected

VS-60601 Mitsubishi Problem...
That model is famous for the CRts leaking onto the chassis which causes all kinds of problems and can cause the main circuit board to short as well as destroy the solder. Try looking at the board for evidence of a pastey substance that would indicate CRT coolant leakage. Let me know what you find.

this might sound odd but you might have a bug or something on your mirror or have you bumped the front screen? the freznel and lenticular screens could have seperated. i would contact a local repair shop for an in home service call just to verify these 2 possible scenario's.
