Hi all looking for some help my LG 50ps300 plasma tv had suffered the red sparkle with poor screen I bought the repair kit and replaced parts including the 8 caps on ctrl board ,now the problem is I have 4 vertical lines in middle of screen which wasn't there before so from reading up got a replacement buffer board which made no difference ?
so I run a program through HDMI Then PC which runs through colours when the screen is green no lines when the screen cycles through red , blue , yellow lines show up but as soon as its green , white or black no lines and also noticed from blue to white screen the lines turn green on white background but fade quickly and cant be seen ?

one more thing on menu screen lines cant be seen but as soon as you move across and it changes to red the lines can be seen im lost to what it could be can anyone please help
Thank-You

hi mate, i have an LG 50 inch plasma that is 4 years old next Feb. I have similar issues and I sent it away to an LG official repair. The internet will tell you its either some contacts inside that need cleaning or a new screen. Well mine will need a new screen at a cost of 300 euros or so.

This is quite a common problem and there is at least one other thread on here specific to this issue.

For me and at the cost, im gonna limp on. Hopefully i will endure it for another 6 months or so (i cant always see the lines due to background colour plus they are on the right and in the main you focus centrally) and then buy a 65 inch new tv and then probably have this repaired too. For 300 odd euros i can almost buy a brand new replacement!

Was hoping it wasn't screen
These lines only come up after the repair to cure the red haze poor image
Was fine before , I have removed all connectors and cleaned everything
I was thinking it was the Ctrl board faulty as if I use a pencil and go across
Contacts on Ctrl to buffer board I can change the lines and make 2 of them go away
So if it was screen surly they would be there all the time ?
Don't ask me I'm new here lol
Thanks for the reply

Yep I sent mine away with two lines and it came back with more!!! now there are about half a dozen. As said at the moment mine are 6 inches or so in from the right hand side of the screen, so dont always impact on my viewing... But 3 1/2 years in im quite disappointed.....

I also found another forum that specializes in electronics/TV electronics and there is a member on there who is an LG specialist/employee/ex employee or something and i asked him and his answer tied in with the LG repair man - a new screen!!!

Like i said 300 odd euros for the repair, i might as well throw in another 150-200 and buy another 50 incher which i could do...but im gonna wait as long as possible and buy a bigger and hopefully better TV next year and then get this one repaired and stick it in the boudoir!!

I think you'll find that is what most of those LG panels suffers from. And its either the contacts if youre lucky or the replacement of the panel itself, if youre not.

Read what I posted above.

I have done nothing about mine as I tend not to notice it and will limp on for another few months and then buy a new 4K or OLED TV. My Lg I will either be repaired or left as is, as I can live with it....
