Re: A guide to fixing/troubleshooting some common plasma TV problems

Thanks Tom.
After My problem appeared I started doing some research and I have been shocked the number of people who have had this failure even on newer Samsungs.
Almost all of them found it to be the panel which is why I hesitate to rely on the y board replacement.
I bought this tv based on consumer reports. I guess I should consider myself lucky to have gotten 4.5yrs out of it. We have already decided to avoid samsung.

Is the IC the chip located underneath the silver heatsink? I might be willing to try that AFTER I bought a new TV for my family

Ah.
That board is $100 at it's cheapest (including shipping).
Not sure it is worth it at this point given the TV can be had for $500 new and it is only 720p.

Any other options for fixing the black line?

Okay.. opened it up. Have a large single board on the right with ribbons labeled LJ41-05307A and a large board on the left with ribbons labeled LJ41-05308A.
On both boards ribbons go to the panel in front. I checked the ribbon connects and all were secure, nothing looked out of place or damaged. Boards all looked in good repair. I have two boards in the middle, one is for all the external connections and the other looks like a mainboard.

Here is a picture of the y sus.
I am wondering if...

Okay.. hrmm.. No longer made... no longer available a lot of place. I guess I will start digging around to find it.

Where does one find the Y-buffer for this?

Re: A guide to fixing/troubleshooting some common plasma TV problems

First post here.. found this when trying to solve my plasma issues. I have a samsung pn50A450 that has developed a single dark line about 4" from the top of the panel horizontally across. Close up it appears to be one row of unlit pixels. This occurs on all inputs.
My TV is only 4.5yrs old. I called the authorized Samsung repair and they stated that it was a panel defect and would cost nearly $1k to fix (Due to needing a new panel).

Is that true or would the Y-buffer solve my issue?...
