Question about Televison & Video

Open Question

I have a Samsung LE40F71B LCD tv about 18 months old. It has started showing red pixels around the edges of blacks, e.g. around a lapel on a black coat or on black hair, etc. Sometimes the sound crackles too, then is ok. The screen may flash very briefly at that point, then is ok again.

    We've got exactly the same problem with our Samsung, purchased in November 2006. Spoke to Samsung about it, they don't want to know as its out of warranty, even though they had to replace the main board shortly after we got it. They suggested someone to fix it, but they want £120+VAT to even come and look at the thing!

On the KDFE55A20 this sounds like a bad Q-Box. I would get an estimate from a Sony authorized servicer as this part may be quite expensive. On the 55A10 model this may be the B-Block and is also quite expensive. Getting an on-sit estimate would be the first step I suggest. Again go with an authorized Sony servicer. Call Sony or go to Sony.com for customer service. Good Luck

SOURCE: LCD TV SCREEN PROBLEM RED HORIZONTAL LINES OF DOTS ALL OVER SCREEN PLEASE HELP

I unplugged the TV and now the picture is back.I read that the LCD's are vunerable to static build up so unless my daughter is using her TV I unplug it.

I was thinking about getting a large LCD for the family room but I'm not going to until they improve on this technology.

Good luck to everyone!.

Cheers.

This is no solution but a point in a probable direction.

A tech guy told me ALL the LCDs they have seen in their repair shop have "swollen" capacitors, this is due to voltage instability. Lowering the internal voltage regulator and replacing the swollen capacitors (which eliminate noise) apparently restores the LCD to new working quality. Without actually "seeing" my problem the tech said that should repair it. I have not tried this yet but eventually will begin that way.

We have the same DLP set and had the same problem. The Color Wheel, P/N BP96-00250A, a $200 part needs replacement to eliminate your problem.

It depends on the size,location and how many dead pixels. If remember less that 5 they won't do nothing about them. Call the warranty people and find out. they will for the location, size of pixel and quantities. Good luck to you.

Black pixels in shading and back ground turning red


This is not a "rear projection" plasma TV for whiuch you offered solutions, It is the LCD Flat panel the Liquid Crystal Display a 40" Samsung. I do not think this problem is a dead pixel as that woulde be "black" Reading on the web I found only one post that appeared to be the same or similar and the person said somehing about "switching the red wire" Maybe it is a "stuck" pixel -- sticks on red once in a while. Like previously after the first time it occured it has not come back in three days now. Samsungs repair comes today i will cross my fingers.

Dark black spots around the edges of LCD TV


this issue is tape from the edge of the panel falling onto the screen.You will have to remove the cabinet and the panel from the bezel(front cabinet).remove the screws from the lcd outer edge. Take of the tape.Be very carfull of the ribbon cable that goes to the lcd controller and to the lcd screen itself. They break easy. If you do , its over. you will need a new panel. to much money and work. best to leave it alone.I have fixed it several times for people with warrentys. It is just anoying but will not hurt your tv.
