Question about RCA F27636BC 27" TV

1 Answer

Picture height adjustment

The picture is too high and I can't find anywhere where the height can be adjusted. It's nowhere on the screen menu and the two knobs in the back are brightness and sharpness.

The screen parameters were factory set by firmware programing during production.

If over time the picture became out of spec, this is due to some components that have changed in characteristics with use and age.

The fix is to have the set properly serviced. The tech will have to troubleshoot the set to find the defective parts and change them.

Picture too low in screen can be from a circuit inside the TV.

These can be caused from among the components in it.

Some channels on my tv are dark and tinted orange, I used the menu button to display the menue and scrolled down to picture but I did not know how to select picture.


Hello
Adjust colour control to zero, and check for a pure black/white picture. Adjust contrast and brightness control to minimum and check whether the picture goes completly off or a slight picture prevails. If the picture goes out when you turn down brightness control to 1/3 position, that is about 20 points, your TVs screen voltage is very low, and it can be adjustable. If the picture does not go out and more brightness prevails, screen voltage is high. If the screen voltage is high, there will be some fine lines across the screen at about an inch apart; on the whole screen from top to bottom.
Screen voltage adjustment is critical for the clarity of the picture. If it is low, no proper colour will be dispayed. If it is high, it is harmful to both picture tube and your eyes.
Never try to adjust it without proper knowledge about it. The screen control can be located alongwith the LOT [Line Output Transformer], of your tv. There will have two adjustable controls there, one is for Focus, and the other is for Screen. Both are interactive, that is adjusting one will effect an other.

Picture is out of line


Hi,
One of the following may be misaligned. i) Aspect ratio of your TV may be wrongly selected. i.e. select 4:3 in place of 16:9 or vice versa with your Remote . ii) Picture Width or Height may be wrongly adjusted. With the help of Remote, select MENU go to PICTURE option, reduce height or width which ever is needed.
Have a nice day Rating the solution is highly appreciated.

VIDEO TAPE WHEN PLAYED WAVE AT THE TOP OF THE TV SCREEN


This is a common problem usually seen when playing copy protected tapes. The part of the picture affected is normally off the top of the screen. Sometimes the problem is also due to the VCR itself and differences in tapes. It's also possible for the TV itself to be causing this, although you would probably also notice this flag-waving (that's what it's called) on regular TV viewing if that were true.

Sometimes increasing the height of the picture can push the affected area off the top again. But this can also cause you to lose part of the picture you want. Also, the height adjustment may be difficult to find as it's not something normally used. On some TV's it's a small pot somewhere on the board, but most newer sets have electronic adjustments through a service menu that you need to know how to access.

I'd suggest trying another VCR first and play one of the tapes you know shows the trouble. That might be all it takes. Then consider trying to increase the picture height if it's just a small bit at the top of the screen.

Picture problem


It's not an adjustable problem and not all that easy to guess at either. Power supply is a usual suspect and my best suggestion would be to take it to a reliable shop for an estimate.
