The black line indicates that either the flex cable that connects the panel to the buffer board has come loose or the panel is bad. Try to reseat the connector located inline with the symptom seen on the screen, if it's loose or inserted crooked, the panel will show this problem. Good luck. Joe Weibel customelectronics.org

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.

1inch black line down right hand of screen


Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages.
Good Luck!

If these are thick black lines, this is most likely line frequency noise entering the set. you may have a leakage from the DC ground on the secondary side of the powersupply to the AC side, or a bad filter capacitor(s). Most of the time it is the filter caps that give these types of problems. If you are connected to cable TV service, or an outside antenna you can also have this problem from an AC ground loop return. Also if there is a device such as a VCR connected to the TV and it has problems, it can cause this as well...
