HI When I start my ALBA TV, there are horizontal lines across the screen with high noisy sound. I bought this TV just few months ago. thank you


The horizontal line in the screen is the problem cause by vertical output driver.The vertical output is located at the verical section.Maybe theres a loose connection in vertical section or leaked capacitor.It also the cause of deffective vertical ic.So its better to repair and trouble shoot by the authorized technician.If you have knowledge in Tv.Try to replace the leaked capacitor.

I am repairing a television TCL2009 the trouble is one line vertical.What is the trouble of the TV.


If it has a vertical line (running from top to bottom) you have a horizontal circuit malfunction. Most likely a loose solder joint in the drive to the yoke. You have high voltage but no horizontal deflection. Thanks

Vertical lines showing. it is an Optoma HD70


If the lines present in the menu when displayed this indicates device mounting troubles. Possibly loose in socket. If you change aspect of displayed image do the lines move, if they do, its an electronics problem, if they are constant, and nothing is displayed in the lines. Tighten device in socket, or seek professional service.

It is a simple trouble, tv has got dry solder joints in the vertical deflection circuit. Resolder vertical output ic pins and related components, this will be okay.

Vertical line splitting screen


We have had issues like this that ended up being the digital convergence module. There are surface mount electrolytics that suffer from dielectric absorbtion (dry out) and they must be replaced. It's much easier to replace the module than to repair it, the convergence will need to be reset once this is done. If you have the original remote control you can gain access to the service menu to reset the digital convergence. Joe Weibel
