Call a good TV Tech and tell him the Convergence Amp IC's need to be replaced. Should not cost over $325.

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.

My 52" RCA P52937SG screen bows on the top and on


What you are describing can be due to a number of different settings.

Focus on the red and green guns
Sharpness on the red and green guns
Horizontal position and size
Vertical position and size.

Please consult a professional for adjustment on these items as they are all near or connect to parts that have Hazardous Voltage.

This is a convergence problem and can be as simple as bad solder connections at the convergence ICs or defective ICs. Can you solder? If so, update this and repost the model number as I don't have your original post.

Thanks,

Double focused, red and green, bow in picture top and bottom


hi
You have a convergence problem
If the set has auto focus and will not complete its cycle.
The Auto focus module is bad, (expensive)
If it completes and the problem is still there.
Then check for bad conv. drivers (stk****) or cold solder joint on one or more of the 3 drivers pins.

Your problem is a bad main filter, a regulator IC ,and or a combination of a convergence problem along with a vertical IC going bad. This set is not something you should mess with unless your a trained tech. Please seek a pro to assist you with this repair. good Luck
