Question about Samsung HP-R4252 42 in. Plasma HDTV

Verticle lines on screen

I inherited this TV from a neighbor for free who was moving overseas and could not take the TV with him. The problem with the TV is that it has a lot of small verticle lines and one think line, probably 1" wide. The smaller lines start to go away after the TV has been on a while but the thick one does not. Just trying to figure out what the problem is, and how much it will cost to fix it or if I should just sell it.

Re: Verticle lines on screen

If you could post a digital picture of this tv I can make a determination, it could be the panel or one of the boards inside the set

Verticle line running down the screen.Thin verticle line running down the screen.

You have a defective LCD panel. The only way to fix it is to replace the whole LCD panel. It is the most expensive part in the TV (usually $500-2500) depending the make, model, and size. It is also time consuming as you need to take the whole TV apart in order to replace that part.

Verticle lines for picture

You need to describe these lines better. Are they moving or stationary? Are they very fine lines with sharp edges or are they more like bands with soft edges? How many lines do you see, and how wide are they (compared to the screen width)?

Fine lines that are stationary: defect in the electronics causing a vertical row of pixels to be dead or stuck. Can only be fixed by replacing major parts.

Broad lines with soft edges that move: could be electrical "hum" interference. Make sure you are using a grounded (3-pin) power plug, and that the outlet is properly wired. (Take the TV to a another location and see if the problem goes away).

Make sure you don't have fluorescent light fixtures nearby--they can interfere with the picture if the bulbs or ballast is defective. Could mean tecon board or display is bad which means replacing both in a sony if they are bad i recomend buying a new tv because it is not cost effective to replace these.

Green verticle line on Maganavox flat screen tv

Most likely it's due to the LCD panel assy failure. It may cost you as much as to buy a new tv. The LCD panel is very expensive in retail market.

Verticle lines on screen

This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
