Flickering horizontal lines

I have this horizontal lines flickering affecting both the upper and lower end of the screen, where reddish lines in the lower end and a bluish hue lines in the upper end. Both of these lines continously flickers, I thoguht it could be convergence problem, and tried to correct it using the remote, usng both the crosshatch method and screen numeral method, am able to all three hues but when you open the screen, the problem remains. anyone, could this be an IC problem, or tube problem. Any suggestion will be greatly appreciated. Danubo49

Sounds like a problem in the horizontal deflection circuit.possibly a solder problem. try re-soldering the horizontal transistor, line coils and yoke pins.

LG OLED Horizontal Flickering + Power off

The model would have helped. Generally horizontal lines in the picture come from a defective panel and the set isn't fixable, you could try replacing the t-con board but chances of fixing it are slim

TH-42PX75U horizontal lines (flickering black and white)

The controller board for the screen is going bad. check shopjimmy.com for replacement parts. It's not a difficult job to do. Once the back of the TV is removed, you'll see it near the center of the screen.

Benq w5000 green horizontal line flickering at bottom of screen

Hi there

This is normally only one of two things : Cable or Mainboard

The W5000 is quite a new Projector and should still be under warranty.

But try changing the cabling first and if the problem still persists , let BenQ replace the Mainboard.

Video flickering

Horizontal lines are either caused by the main logic board, a dammaged screen or by the main x and y drivers. Hard to determine which one it is, but somthing is getting hot which is causing the problem. My guess is the main logic board.
