Samsung HP-R4252, white vertical line

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...

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...

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.

HP-R4252 NOT LCD TV
IF LCD TV has vertical lines try cleaning T-con board to lcd panel cable or replaced t-con board

this can be in your video cable or LCD Connector issue. but most problem is in the flex cable of LCD. some other cases cannot be fix and replace new LCD Screen.

Need to check the two things.

1st -- need to exchange T-con Board.
2nd -- need to exchange the cables between T-con & LCD panel or
between T-con & Main(LVDS cable)

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.

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.

Sounds a lot like the Power supply board. But you have to check it out further to be sure. Email me back and we'll chat. GURU JAY

Well sound as if a segment or Ic driver has failed on the panel. And a 42 inch replacment panel can run you $1250.00
