I have a SAMSUNG HLP5674W and it has begun to make a Loud buzzing/humming noise from the rear of the tv... It sort of sounds like a fan and when i listen closely, that area is exactly where the noise is...

pull the light assembly out clean it with a vacuum and some pressurized air spray and place it back in the TV, while it is out check the fans on either the inside or in the removable assembly for damage or other interference in operation...If this doent help dissemble/remove the rear of the enclosure ( 6-10 screws) and clean the insides carefully and then turn the tv on - being careful not to be touching ANYthing and see if you locate the culprit.....

This could be due to some electrical interference. Make sure you are using a grounded (3-pin) power plug, and that the outlet is properly wired. For that 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.

Sony kp-61hs10 tv, has sound but picture goes black after 3 min.

I just had the same problem. If your lucky it might be a free 5 minute fix. The five light flashes mean impropper current. I took the front grill off, then behind that is another black cover, I took that off and noticed the circuit boards COVERED in dust. I then took an air can duster and blew off all the dust... works like new. No more flashes and in an out picture. The collection of dust was interfereing with the electrical current.

Just bought a samsung ps50a557s3f 50" plasma tv and the picture isnt very good.Have only got normal sky at the moment and i was wondering what the best settings are

Hi Smudger

Not sure if you still have this issue, but i have just bought this TV & also use sky (not + or HD)...

I got myself a Monster Cable Home Theatre surge protection unit from comet, basically it helps filter out all the background interference (picture & sound) & helps boost the signal sent to the TV..

I use a gold plated scart lead from the sky box to the TV & the picture is spot on.......i've not noticed any ghosting/pixeling etc & am well impressed...

The unit came with a top end HDMI cable & cost £135 (bit excessive you may think, but to buy the unit & cable seperate would cost £250!!) + the cable is a 'cable for life', so you can get a free updated cable as technology progresses :-)

My sky signal was always at half power (you can view this from the sky menu options) & now its almost full signal

I'm trying to get the best picture for my 50'plasma tv. the picture is nothing like the one on display, and i've bought all the required gear

If you are using anything other than the HDMI input with HD programming the picture is going to look blotchy, when you see the tv on display, they are always playing a dvd disc and never have it on cable or satellite channels, this is because since the dvd is a digital format and looks very clean, by using the non-HD connections and since your tv has a digital tuner (mandated by the government) the tuner picks up interference from cell phones, WI-FI and police bands along with the cable signal and gets processed on the tuner, when everything goes to digital in Feb 2009 that will clearup considerably, but as for your question HDMI is the optimal connection to use

I'm sorry to say that those lines or interference are cause by a hardware failure and no adjustment can correct it.
If your TV is only 6 months old, still cover under manufacturers warranty. Call the manufacturers and ask them how to go about this repair and hopefully they will send you to an authorized service centre.
Hope this helps.
