It's the gas you need to have it re regass

The manual for the part number you provided for your TV is available from Samsung from this website. The manual provides instructions on installation and use. http://downloadcenter.samsung.com/content/UM/201104/20110426140020273/BN68-01920B-00L02-110426.pdf

That problem is usually cause of faulty y sustain board..It is looks like OK but the system was faulty..Try to replace it to fix the issue..

Suspect the main board in the set that processes all information.Google the model number with "parts" which ought to lead you to shopjimmy.com who has by model number a list of all boards in most of these sets that are used with part number and costs.

I don't have a solution but my Samsung 50" 720P Plasma is doing the same thing. It's already been in the shop for a new panel and now just after the warrenty runs out this happens. I'm NOT recomending this TV to anyone. NO MORE SAMSUNG for me...

That is because you are trying to display the 4:3 old standard TV source to fill in the 16:9 screen. If you want to watch it with correct aspect rarion, you will need to use the 'ASPECT', 'PICTURE MODE', or 'WIDE' btton on the remote to change it.
Most people does like to see black bars on the left and the right sides of the picture when view in 4:3 mode so they stretch the picture to fill the screen, and that is what you will get, people will look short and wide.
Please see your owner manual that will explain the aspect ratio of the pictures in various modes.

it has a shorted parts commonly in the power supply.

EXTREME DANGER!!!!!


PLEASE LISTEN CLOSELY:

all appliances made in the last forty years have a polarized power cord.

One pin on power plug is small and other larger--the larger goes to the neutral side of the electrical outlet.

If you get sparks when you hook up the coax to the cable fitting--only one of two possible reasons.

Either the polarized cord has been defeated (plug modified) or the outlet you are plugged into is not wired right.

Understand--it does not have to be at the set you are using---if somewhere else in you home a cord is defeated or an outlet is bad--it will feed the problem via the coax to every other set in the home connected to the same line.

What you are seeing if you get sparks is the coax fitting has 120 volts AC getting to it either by the coax or from the power outlet--

The easy way to find this is disconnect all coax connectors in the home and with a voltmeter hooked to a earth ground (like a ground rod or pipe made of metal) measure for AC voltage to the coax.

THIS IS A VERY DANGEROUS SITUATION-BE VERY CAREFUL--

If even one set or outlet is bad it will feed this via the coax to all sets in the home---I have seen this before-yes it can destroy a TV! but it can also hurt or kill someone--this is the reason all power cords are now polarized.

IF YOU HAVE ANY QUESTIONS ASK ME--IF IN DOUBT HAVE AN ELECTRICAL EXPERT CHECK THE WIRING AND MEASURE FOR AC VOLTAGE TO THE CABLE--ac voltage can kill--it is the same as connecting a wall outlet to the exposed areas of the set.

THIS IS SERIOUS STUFF--DO NOT TREAT IT LIGHTLY!
