Re: LG 50PK550 Red vertical line on LHS of panel

Thanks alot, tried all as suggested, looks like its the panel, I'll survive for now.
All help has been appreciated!

Hi there,

My LG Plasma (LG 50-PK550) has started to develop a thin red line on the left hand side of the screen. I've run a pattern test by shorting the jumpers on the control board, but the line is still there, so I've put the inputs out of the equation.
So, my question, is it the control, X-board or the panel kaput?
I dont think its the latter 2, as red, black, white and gray still display, but I'd like to have your point of view.

Thanks alot and kind regards,

Michael

Re: LG 50PK550 - Screen flash, then gray

Ok, thanks, I'm going to try see if I can get into the board using the serial port and using Putty to see if overwriting the firmware would work. How would one overwrite or flash the firmware using the serial port? What are the commands I'd use?

Hi there,

I have a LG 50PK550 Plasma. Last week, the TV suddenly powered off while playing music from my RASPBMC setup. I disconnected the TV from power and reconnected, tried to power up....
The screen flashed for a second then went gray and stayed like that. The remote and front panel controls are unresponsive.

I removed the back cover and tested the SMPS's fuses, diodes and power resistors, which all work. Then I tried the AUTO_GEN test pattern, with the LVDS cable disonnected from the mainboard.
The test pattern worked!

Does this...
