I have a 37"Samsung LCD and having just spoken to the Sky engineer (also a friend) he says it is a national problem between Sky+ and Samsung. I have the same problem when on playback but not on real time? If you had your box changed to an Amstrad what sort did you have the problem with?

If the samsung is more than two years old it is probably the Tv. I have a 42" samsung and the color blue will appear all over the tv for awhile and then go away. It started after two months and I just thought it was from playing xbox. I believe its a known defect in the tv or related to burn in. If you got it from a store use your coverage on it

Hi.

Your problem sounds like the lead that connects from main pcb to the lvds pcb.

These have gold coloured connections that become tarnished & dont make good contact.
You can try to sort this out your self but please be very carefull the fine wires on the plugs can be easily damaged.

If you do decide to have A go you will need tin of air duster & elecrical spray switch cleaner, You are only to clean plug & socket connections on lvds lead & pcb.

SOURCE: My new Samsung flat panel

Hi,

At best described, your unit is getting RFI (radio frequency interference) or basic electrical noise. Such could be brought about by other electronic devices physically near the Samsung flat panel LCD TV which may include (but not be limited to wireless phones, electronic ballast of florescent lamps, VCR/DVD/Gaming consoles with Channel 3/4 outputs.

Possible corrective actions:

  • the simplest, move such devices away;
  • try using a power filtered strip;
  • try plugging other devices in another wall outlet.
The technically correct procedure would be to improve the shielding of all these devices including the Samsung but that would be beyond normal user actions. Additionally, it should have been addressed in the manufacturer's design in the first place.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

in these issue you can see vertical lines due to filter capacitors bad in the secondary power supply. 100micfarad/j35volts, 220microfarad/25volts.

Hi, A lot of these LCD screens have the same problem (strip of white,blue,red) lights on the screen.
Try this move the TV to another room to rule out any interference. Check all connections on back.
Good luck.

What does it mean by dead cells?


I assume this is related to your LCD monitor.
I think you mean dead pixels. The LCD monitor has tiny pixel elements, one for each red, blue, green color and each one of these colored pixels are turnes on by a transistor. When a transistor fails then the colored pixel it controls does not light up. This is a dead pixel and it shows up as a tiny black dot.
If the screen displays a blue screen, a dead blue pixel will appear as a tiny black dot in the blue screen.
You normally would not notice a few dead pixels unless they are grouped together.

Pixelated lcd tv picture


usually this issue is caused by a week signal issue, those tv's need a stronger signal than an analog tv, i would call the cable company, have them come out and hook a meter to that cable, they may sujest a house amp, usually charge 50 bucks for it

SOMETIMES I CAN SEE A BLUE DOT ON SCREEN


Most manufacturers consider a few dud pixels to be normal and not a defect. Especially if not in the center of the picture.

Don't get fixated with watching the dot, look at the overall picture. It is like staring at a pimple on a pretty lady's chin.

You need to adjust the panel voltages, adjust the VS voltage to around 186 volts, if that doesn't change it then adjust the V-Scan voltage down, turn the unit on and apply a video source to it, and while adjusting the voltages look at the screen and you should be abe to watch the video noise fade out.

Faint Horizontal Line


Your problem could be a bad LCD screen, and beleive me will get worse with age. It could be a Driver IC is not putting out the proper drive for that matrix of TFT. If you have a warranty, stand by your guns as its not right, so call and have the servicer make it right. Good Luck PS please do not forget to rate this thread.
