Question about Mitsubishi WD-60735 Projection Television

1 Answer

I have a slightly arched pink & green line accross the top of the screen.

The line is horizontal, translucent, & fairly narrow (slightly thicker than an inch) it's a pinkish color on top, with a blueish green color underneath that. The line is arched in a downward manner, thinner on the sides of the TV's screen & thickest near the center of it. The picture does not seem skewed or otherwise in error, the translucent line appears to be the only trouble.

    It is the correct model number, the set is one from the V39 chassis series of DLP TVs, it is the 60" set.

    Either a issue with the light engine or something on the optical light lens---could also be a gasket for the screens hanging down enough---anything that gets between the rear mirror and the screen will standout like a sore thumb on the screen.t

    Thanks! I suppose I should start with checking the gasket--seems like the simplest--then I'll make sure the lens is clean before i look into the light engine.

I am wondering if we have the correct model number listed here? If so with the model listed either something is inside like a spider web or that model uses a optical light engine which "might" be able to do this if bad.

This sounds like your convergence correction amplifiers have malfunctioned. These Integrated Circuits often burn out after a few years (STK392-110) they can be replaced with a higher version (STK392-150) However it is important to have the biasing circuitry checked to make sure nothing has burnt out as a result of the ICs malfunctioning. If you have a background in electronics you can repair this problem with very little effort, however if you do not have a background in electronics, I would suggest that you have your TV serviced by a qualified TV technician.

 

I hope this helps,

 

Thank you,

horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.

I expect the answer to your question is YES! The convergence amplifiers are a common problem in many projection sets. When you search for the replacements you should find that the originals have been superceded by improved parts. Also be aware that when these parts fail, they will usually damage a resistor in the convergence yoke return path. The resistor must be replaced with one of the correct value or the convergence, though responsive, will be out of range.


If you find my suggestions to be helpful, please share with us some details so that others may benefit from knowing the whole story. Thank you!

How do I correct pink and green bands accross HP-R4252 Plasma TV


First of all try, changing the input device to some other and see whether you see the same problem. Then connect your present input to a different TV and see. If you feel the input is ok, and it is a problem in the display, this is a case to be handled by a qualified service technician.

You have some bad capacitors. They are located very near and next to your vertical IC. I would guess you would have to replace maybe four of these! Thanks for asking!

My 15 year old Toshiba Televisiononly shows a narrow horizontal band in the middle of the screen. Sound OK.


Hiii fairley,

You aren't specsificly dercribe yor tv set.
For common TV horizontal problem ;i.e : White line accross the horizontal screen, horizontal band,etc..it's can solved by replacing the IC Vertical/Transistor, and olso to replace the cap nearest the IC.

For common TV Vertical Problem :i.e : White line at the center of the screen (top to bottom),Vertical band,etc...It's can cure by Replacing the Horizontal IC/Transistor,and offcurse the cap's.

Tha's what all I know....

Hope can help you to solved the problem.

Thank's

Arched pink lines across screen. Now green and pink double stacked wording.


Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture
