Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up


Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

Picture Bowed towards the center


It is a convergence problem, probably one of the convergence ICs has blown and must be replaced. Call the number in the last pages of your user manual to get repair service in your area.

There is a wave/bow in the bottom and top of the picture on the screen of my Toshiba 70HX50. When I am in the grid screen in the service mode, it looks like the center is 'bowed' out. How do I adjust this...


Slight error in the alignment of a projection TV is pretty much normal. If the problem cannot be seen on a normal TV picture, I would not spend the money.
However, if the problem is severe and causes colour double images, it is convergence and will need parts replaced - about $200-$600 depending on service call, parts, labour, etc.
Minor adjustment takes a skilled technician. attempting it yourself will likely cause the set to stop functioning. (Digital adjustment is not forgiving)

Bowing of picture at top and bottom towards center.


Projection sets have two very common problems outlined below.

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. The TV can also shut down when the convergence starts to fail.

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, RCA and others.


You can more info and a DIY convergenece repair kit with instructions from TV Repair Kits using the link at the end of this article.

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

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped or bowed
*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

Bad picture


Are the convergence controls also out of adjustment? Please respond to this same post and I will help you. If you could post a picture of what the screen looks like that would even be better.
