This may not be an issue with the LCD panel, but more likely with the cable itself. Make sure the connections leading from the motherboard to the panel is secure on both ends (this includes the connection that branches off to the inverter). If this does not solve the issue consider replacing the cable, they are fairly inexpensive (10$) on ebay.

If the cable was replaced at the same time as the LCD and the connections are secure, you may be facing a video chip problem, which is irreversible without replacing the motherboard.

Testimonial: "Replacing the motherboard. Might be more economical to buy a new unit, if this solution does not work. What do ya think?"

    A new board can cost 200-300$, You can get a whole new system that is faster for around 500-600$. It's certainly easier and hassle free but not exactly cheaper. On the plus side you'll be getting a faster machine, and selling the Extensa units on Ebay or Craigslist will return some money on the investment.

My Dell XPS 9530 has a white vertical line on the display


Fixing this old of a TV would be a waste of money as unless you have the testing gear and expertise you would be guessing. Just buy new and be happy. You could also join a book club and give up watching TV altogether. LOL

Sony 40 inch lcd television


Call Sony!! It Will get worse!!! The panel has ribbons that have fine wires that are used to show each line of information on the screen. Either the panel is going or the wires are loose. Either way, the panel needs replacing. Just hope to God it's under warranty or if not, sony will help you out with a buy-out.

White lines equally spaced 1" apart.


This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.

Thin horizonal line in middle on dark screen


The several thin white lines at the top of the screen is the warning that the vertical output IC is not getting the boost voltage it needs to run correctly. The IC cannot operate for long like that and shorts out inside, which is when the vertical collapses altogether and you get the thin white line through the center of the screen. The good news for your son is that he had nothing to do with that, and it has nothing to do with the cable F connector. The set needs to be serviced by an experienced tech who will restore the boost supply and replace the vertical output IC, and when I do that I charge $75 but techs in your area will vary, so be sure to ask around.

Hello, one of possible solutions is to replace capacitors (10uF/50V) on HYPER (PD0246) module. Please ask the tech to check/replace them. If you need more info please advice.
