The mostly persistent thin blue line on my 5-yr-old LG plasma TV.

Well, I’m going to try and repair my LG Plasma HGTV. The model number of my LG Plasma is DU-42PX12X.

Here’s the story…

A few weeks ago, my 42″ LG Plasma HGTV began to occasionally display a thin blue line on the right side of the screen. It would appear for a while, then disappear for a while. We are now going on about 5 weeks and it is always on the screen now. It is about 1 inch wide and is about 6 inches from the right side of the screen.

Of course, the first thing one does these days when something like this happens is to hit Google.

Apparently, after reading only a few blogs, I have been lucky. Many LG TV’s purchased in 2004-2005 had this problem after only a couple of years and most of the blog posts are from a couple of years ago.

I got away without the problem for 5 years.

After checking out only a few Google results, I landed on a blog post that had very detailed instructions on how to fix the problem. The comments on the post were lengthy and most people who followed the instructions sucessfully fixed their TVs.

So, this morning, I ordered a LG Electronics / Zenith “Hand Insert PCB Assembly” – part number 6871QCH038C from partstore.com. The part should be here by next weekend.

I’ll update this post when it arrives and let everyone know the outcome.

UPDATE: Transplant surgery on the 42″ LG Plasma HGTV was a success, fixing the 1″ blue line running down the right side of the screen.
