Question about Televison & Video

1 Answer

We are getting color separation on the entire screen, and a concave distortion at the bottom of the screen. The tv is about 10 yrs old, so if it's a relatively cheap fix, we'll keep it.

Thanks for choosing Fixya for assistance in advance!

I would like to know model and make of your TV?


On some TV, these is done through the Original remote

in conjunction after checking the components on the

Pincushion and Convergence Circuits.( Auto focus )


Should you feel you can DIY and have the tools and

equipment I can guide you where to look at .

and the possible components to check.


On some it is a cold solder joint but a visual and

actual check may confirm these.


These circuits are usually connected with the Vertical

and Horizontal Circuits which employs horizontal

output Transistors that is connected to the

Flyback

I will post more once i know the

make and model of your unit to help you.

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

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

RCA-picture discolors, goes concaved


Sounds like a capacitor in the power supply is beginning to fail.Unless your good at this type of repair, I would call a tech to have it serviced. And I would also not use the set until the problem is corrected, or it could get real expensive to fix.

Sony Trintron KV-36HS500 TV color distortion


Sounds like the set is out of degausing, you will need someoen with a degausing coil to come and fix it. Should take all of 10 seconds and cost $100 or less. Let me know if you need more help.

Convergence problem


The convergence ICs are located on the left board on a huge heatsink they should be STK392-110 or STK392-120. You can get replacement ICs at the following link and they also provide free step by step instructions on how to remove and install the new ICs.
