Question about Samsung HP-R4252 42 in. Plasma HDTV

1 Answer

Samsung HP-R4252, white vertical line

There is a white vertical line on all sources, and with all cables disconnected. I tested with several screen adjustments, but non made a difference. It seems as though the line is on top of picture or even blank screen. I called Samsung, and the warranty expired, and I called a local tech, but they want 100 bucks just to tell me what is wrong by coming to my house, and they won't guess what might be wrong. Any help will be greatly appreciated,
Thanks.

Unfortunately you probably have a bad lcd panel. This is caused by the heat of the panel releasing the solder that holds the ribbon cable that supplies the picture information to the panel. A lcd panel is more often than not, more expensive than getting a new tv, also the new tv will come with a warranty. Most of the unit I have had this problem with were uneconomical to repair. Sorry for the bad news, Hope this helps.

I have a permanent dark/black 4.5" wide vertical line on left side of plasma TV. It seems as if it is 4:3 display mode on left side only. Any help would greatly be appreciated. I have no problem changing...


Hello,

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER .

BUT IF OTHERWISE CHECK
x driver cables 10 ohm resistors have loose connections
Hope this will help...

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...

Vertical Line started on left side of HDTV, and now


This problem is down to the actual LCD or plasma screen, if this shows as the screen warms up and stays on then the screen will need to be replaced, you should go back to your retailer (not manufacturer) and report this problem, depending on the store and how long you have had the tv, the tv can be replaced for a like for like tv at store as this is not a cheap standard repair.

Vertical lines across my entire screen


My 42" Samsung Plasma HDTV HP-R4252 has a 2" vertical strip of green pixels down the right side of the screen.

My 3 year warranty with Circuit City expires in Nov 2008.. so I hope I'm covered.. can't call until the morning.

Samsung said it might be a logic board problem.. but they want almost $2000 to fix. I might as well buy another TV if Circuit City can't fix it.

White lines equally spaced 1" apart.


This is probably caused by the small signal board. It controls and decodes the picture information before it is sent to the display panel. It can be fixed by a quailified technician and if you contact philips (this is who makes magnavox) they will tell you the closest certified technician. Hope this helps.
