Horizontal lines on Samsung Plasma


Hi,


The most common cause for the loss of picture is a bad Horizontal Output Transistor (HOT). but I would suggest you get a detailed estimate. I think that this would cost you about $60.

The horizontal lines means the vertical amplifier or deflection system has failed. There are over 100 components in this section and any one of them, or most of them can be at fault. However, the most common failure is the VOT or vertical output transistor (which is often buried inside a chip).

The repair will cost around $150 plus or minus.

FEW TROUBLESHOOTING STEPS YOU CAN TRY:

ONE: Do a hard reset (just to make sure there is nothing in the coding that is fowling things up). Unplug the power cord; leave it disconnected for 4 hours. That will restore everything to factory defaults when you power it back up.

TWO: Do the "whacking test" by banging your fist on a few strategic places to see if there are any cold solder joints or loose wires acting up inside the set.

If the above steps don't solve ur problem then I suggest you to go for a repair if you don't have any knowledge of repairing it.

Goodluck...

Samsung plasma tv ps42c7hdx flickering lines


Yes, yes, yes. Change all bulgy, puffy capacitors by exactly the same value and voltage. Look for any excessive voltages in these areas where you find such capacitors. But replace capacitors only one by one. Never remove all of them together, as you are likely to misplace the capacitors, creating more problems. Also look for any loose contacts and dry solders.

Horizontal Black Line on Plasma Screen


On the Panasonic if you can open and repair problem you can be helped. If not call a repair center. On the Samsung I'm afraid the Repair guy is right. If you can see the line with Unit turned off then it is not electronic failure.

Sorry I did not have good news for you. Let me know about the Panasonic Plasma. Could be dirty contacts from the x board to the display.

Samsung Plasma TV - picture has 6 sections of horizontal lines


All I can say is when you watch T.V. the plasmas run off of plasma gas and when you leave something on for so long it burns in the screen. I have the same T.V. and when watching like the weather channel it leaves lines but they go away. If yours are permanent then you can't do anything, but it may help if you go on your remote and go to "menu" then look for "setup" and scroll down with the arrows on your remote. Look for "screen burn protection" and select "white screen". This will make your whole screen white and it may take out the lines. If you let it sit white it won't hurt it. All one color won't hurt, the only thing that hurts is like bright white lines in front of a dark background. Just give your T.V. a break from time to time ESPECIALLY ON VIDEO GAMES. T.V. shows that are HD usually have their channel icons that move or are very dim and they won't hurt. Just go to what I told you and let it sit about 20 minutes, if that doesn't help, then the T.V. you have i believe comes with a 2-year standard warranty and if it's under warranty take it back if you have the reciept. If no reciept then call 1-800-SAMSUNG.
