The problem with your TV is the screen tabs this is where the electronics bond to the screen a technician may be able to fix it with compression pads otherwise it a new screen

The tv board call the T-CON decoders board have problems,that why colors vertical lines are showing up in the tv LCD screen panel.The T-CON decoders board,this board sit wright at middle bottom of the tv LCD screen panel.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish T-CON decoders board for the replacement.

The problem is a defective LCD Panel.

hi

I think your TV have a trouble inside lcd panel
the controller board contains driver IC. Deffective driver IC can cause of line display.



Three reasons why one vertical line accross screen can happen in LCD;

1.The missing signal from the controller IC to
LCD driver.
2. LCD driver IC itself defective
3. Dry contact in the tape carrier package.

Use masking or electrical tape to mark it where the line was located. press it if the line back to normal but when release your hand came back i think it was intermittent. Open the LCD panel


Use robber

Place the rubber on the top of TCP

Gently close back the top casing


Good luck...

Similar problem with an eleven and a half month old LT-40148. Approx. 1 inch vertical banding line on left side of screen on all inputs. After about two weeks, same problem on the right side of the screen.

Fortunately this occurred two weeks prior to the one year warranty expiring.

Called Mits customer service and they referred me to an authorized service center who I happened to have dealt with before.

They picked up the set. The front panel (LCD screen ) had to be replaced. Set was gone for two weeks as parts were not in stock. There was no charge. I hope this screen last more than a year.

I had this, and it was just a small connection that was loose.

I had a similar issue. Took it in and apparently i had 4 bad capacitors and after replacing those, my tv was perfect. But I think I lucked out on this one. :) try it.

Had this same issue on right side of 52" about 1 inch from side but had 3 vertical lines that disappeared after 40 minutes. Have Samsung LNT5265FX/XXA and about 16 months old. LCD Panel itself had to be replaced to fix it, fortunately had extended service plan

Pix looks like a light pipe issue, inside the Light Engine. as far as the shutting down, could be a bad fan causing the grinding and when stopps the DMD turns the set off.
