Tx-p50s11e panasonic vertical lines - Panasonic TH-42PD50U 42 in. Plasma EDTV

sounds like a hdmi fault on the dsp board

Your problem appearing after the TV has 'warmed' up indicates a faulty electronic circuit board/power supply: if not under guarantee, it may not be cost effective to get it repaired.

Other than taking the television to a repair shop not much can be done. I recommend a new television. Excellent brands are Sony, and Samsung. Both brands are quality televisions. Best of all you can order them on Amazon.com for lower prices.

If the TV does the same with two different DVD players, it must be a menu setting on the TV. Look through the TV menu options.

HI,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER

GOOD LUCK IN RECTIFYING THE FAULT, THANKS

Change the vertical IC they are damaged

it you have a repair skills you need to open the TV and make sure all the ribon connectors around the circuit boards are proper connected
and if all seems to be ok, the DG board will need to be replaced.

If you dont have any repair skills I would recommend you to take you TV to a repair shop since this is complex repair

It is usually caused by problems from lead solder that sometimes does not connect, so there are some points of the components that are not connected with lead solder to the circuit. if it appears vertical line means from the IC (integrated circuit ) Vertical, you can solder all the points in the IC ( Integrated circuit ).

A line on an LCD, either horizontal or vertical usually means the video driver board is defective or the screen is defective, does it show up as black even on a dark screen? That means a line of LCD "shutter"s is not working and there is a problem that cant be fixed by a reboot or channel change. Bummer.

No Colin, Its not the Tube. The problem is a vertical sweep falure. it could be just a driver/output IC or could also have a problem In the sweep power supply where The voltage that supplys the B+ going to the vertical IC could also be defective. Its not a repair a user should attempt to do as it's soldered into place and you can get hurt if not experienced with these types of TV repairs. As to the cost It depense on how much you like the set and if you can find an honest repair person to do an honest job? Good Luck
