Is there an adjustment for pincushion?

The problem I am having is a slight pincushion. The top and bottom of the screen are stretched, the center is normal. The sides are not dark, it does not look like an hour glass, so I am not sure if this is a true pincushion or not. My computer monitor has a front panel adjustment for this problem, as well as several other common picture problems. Does a television have the same type of internal adjustment or is it more of a component problem?

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 screen is stretched with a 1 and ahalf inch black space on the top and bottom


Most LCD monitors have a couple of control buttons at the top or on the side. Inside the menu, there should be an option called "Auto Adjust" which senses the input signal and resolution, and then shifts the monitor to match it. Have you tried to auto-adjust the screen? There may even be a button called "Auto" on the monitor.

Have you ever had this problem?


Sorry Ginko, but a convergence problem would have the curves down from the top and up from the bottom. The hourglass shape is a pincushion problem. This can be as simple as a bad capacitor in the pincushion circuit.

Could you please confirm the model number so I can look up the probable part?

Thanks,
Dan

Monitor resolution


Sounds like either the trapazoidal is off or the pincushion is set improperly. You should be able to find those settings via the monitors onboard menu. Either one can create such a problem.

You might also check into finding the factory defaults selection. This will reset all of the resolutions and refresh rate settings.

When you adjust your screen follow these steps in order...

Pincushion : Makes the screen look like ( ) or ) (
Trapazoidal : Makes the screen look like / \ or \ /
Horizontal : Basically stretches the screen wider or skinnier to fit the monitor
Vertical : Basically the same as Horizontal, only with the up and down properties
Contrast / Brightness : Use this to find the perfect white and blacks
Color : Finish your setup with adjusting to the perfect color.

This way you can always have your monitor set like you want it.
