FINE LINES HORIZONTALLY ACROSS SCREEN, ABOUT 2 INCHES FROM TOP. SCREEN IS DISTORTED ABOVE THESE LINES


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, greenish, or blueish or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Mitsubishi 65 in has greenish blue coloring mainly at bottom of screen any idea's?


Projection TV sets have two very common problems listed below.

Problem #1) 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

Distorted picture


Sounds like you have bad convergence ICs or maybe I doubt it but maybe a bad tube. Convergence ICs go for around 15.00 each you will need both of them. I tube if you need one and I doubt it IF it is available should run around 110.00-200.00 some where around there.

Floating lines in picture


"Floating lines" usually caused by bad cable signal. Try playing a dvd or tape. If lines are gone, tighten all cable connections. If lines are there, you could need convergence repair if any colored shadows or ghosts are visable around on screen lettering. Hope it's some help anyway.

Toshiba 56HM195 56 in HD DLP Loud Buzzing and color distortion


If the sound, sounds more like a Hum with some vibration chances are the Cooling fan located behind the lamp is going bad, about $20 to repair, if its a high pitch hum most likely the Color Wheel and if thats the case about $30.
Good luck, my fan just went bad now seeing green dots everywhere, so debating on just junking it out or fixing it, with winter coming on might just breakdown and buy LCD and say the heck with DLP from now on.
Good luck to you..
