Question about Mitsubishi WS-65908 TV

Mitsubishi prjection screen WS-65908

I have a 65" Mitsubishi TV. The screen started to look out of focus and the color was off. At the bottom of the screen it has an ark or a curve look to it. It used to happen once in a while and clear up on it's own. Now it stays that way most of the time. I tried to adjust the convergence with no luck. The convergence would only adjust left and right not top and bottom.

    I have the same problem. Tom, how old is your tv? I believe I got mine in '01. Does the picture seem almost distorted along the left and right edges?

    I have a similar problem. Mine was probably '02 or '03, I haven't looked.



    Having repaired televisions loooong ago, I'm leaning towards a voltage regulator. Mitsu used to have problems with cold solder-joints that would finally fail years later - don't know if that's still true, but it's a long time here.



    My specific symptoms are:



    When first turned on, the picture would pin-cushion (pull in in the arc you describe) and be horribly out of convergence (R/G/B distinguishable). After a "few" minutes, it would stabilize and pop back into convergence and the pin-cushion wouldn't be noticable. Now, several months later, I'm getting no power-on at all. Fuse is good, power is good to the transformer. I haven't pulled the board out and pushed any further - those huge flybacks make me nervous. ;)



    If this were 20-25 years ago, I'd say for sure it's behaving like a bad regulator. Looking at the boards in this unit - they look like 20-25 year old tech...



    I'm actually searching for a schematic since there's clearly more than one regulator on the power board.



    If I figure it out, I'll post back.



    Thanks!

You have a convergence problem,all this sets show this problem sooner or later,you have 2 or 3 amps for the red,green blue colors and this amps go bad and need to be replaced then you have to do a convergence aligment from the service mode and not form the customer controls,a qualified tech should be able to correct the problem since is a common one.

The Color On My Mitsubishi Rear Projection Tv model- WS-55908 looks to be off, picture looks blue and Yellow.


its sounds like the convergence on your TV needs to be adjusted. (this adjusts all of the color guns in the back of the tv to line them up again, when they get off, you start to get yellow blue or red halos around objects in the picture. In the setup menu on your TV under picture or Display there will be an item that says "convergence" follow the instructions in there so all the crosses on the screen no longer have colored halos anymore.

Horrible picture on top & bottom of screen


I wouldnt reccommend that you try to fix it as it is a lot easier to make it worse that better. Basically your color guns have gotten un focused and will need to be adjusted. Call a tv tech and they can usually fix it for a decent price.

Focus


Use the Setup menu to select English or Spanish as
the language for the menus and on-screen displays.
Adjust Color Balance Automatically or manually
(PerfectColor TM) using six colors, Magenta, Red, Yellow,
Green, Cyan and Blue. Reset the Color Balance to the
factory default settings. Align the focus (convergence)
of the TV's projected light beams or reset the focus to
the factory default settings.
