Plamsa TV Screen Issues

I have a Harsper HP-4250VPM Plasma screen that just started to display red, blue and green pixels in random patterns throughout the display area. Some flash on and off and some remain constant (mainly the red ones seem to remain constant. The picture remains visible but distorted in the areas where the pixels are. There is one horizontal band area roughly through the center of the screen that maintains a clear picture. Any ideas as to the cause of this? I unplugged the TV overnight hoping it may have reset something but this was not the case.

Ok above are links to training manuals, really you need to get a Service manual, for your exact make and model. I searched, but couldn't find any. So use these generic manuals, and see if they will help you zero in on the problem all Plasma and LCD are all basically the same.. This sounds like a board fault, I think you will find that in the manuals this problem is directly addressed.
It is usually, my professional opinion though that everyone should take their units to their manufacturers approved service center, contacting a head office, of your unit & getting an approved service center is just SO important, even worth the extra to ship it, you see, at those places, the Engineers, are trained on the equipment you have, they usually have parts on hand, and do the job quicker. Anyway do that and get a "Quote". This way, at least, you'll know weather to repair or replace.

Hitachi ultra vision tv stuck on on moment please screen


Another malady common to plasma TVs are stuck pixels. This is where a red, green or blue pixel will fail to reset and remains conspicuously on the screen in the midst of the new images being displayed. There is a useful third-party program called JScreen Fix. This utility stimulates the pixels in the television through an intensive and prolonged burst of colored static. Many times this is enough to remove the stuck pixel. To utilize this program, you will need to run it off of a laptop that is hooked up to your plasma television. To download JScreen Fix, http://www.jscreenfix.com/

What is the part number for glass on 60pg60


Usually plasma TV problems start with the screen. If the plasma screen is broken or crashed, it's not repairable any more . It needs a new plasma screen replacement, which may cost you more then the plasma TV itself. ( new screen run ..2 -3k in real life .) Budget management !!! Protection front screen (glass on front) can be easily replaced and not so expensive as PDP panel behind it. If you have just protection screen damage your screen(PDP panel) will work without any problem . Plasma screen contains - aluminum base and two pieces of glass with gas between them ( gas inside not rechargeable ). Pixels with gas , controlled by small electrodes . Each pixel contains 3 colored sub pixels : they are green, blue and red. Plasma screen works in 2 steps:
--- gas ignition

Rainbown lines on screen no clear picture


Hi
I would check your aerial and the coax lead from aerial to your TV to ensure that is ok.
Have you tried plugging in another video source, ie dvd player / vcr / etc.

Where can i obtain a lamp for the hp plasma tv model#pl4260n


Sorry, your plasma does not take a lamp.

"Plasma flat screen technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light. This light illuminates the proper balance of red, green, or blue phosphors contained in each cell to display the proper color sequence from the light. Each pixel cell is essentially an individual microscopic florescent light bulb, receiving instruction from software contained on the rear electrostatic silicon board. Look very closely at a plasma TV and you can actually see the individual pixel cell coloration of red, green, and blue bars. You can also see the black ribs which separate each."

Green Screen - LG 42PX5D


hello, seems to be panel trouble, plasma and lcd main panels are not fixable, the color green isnt a good sign or it is a symptom of the panel being bad,
i know its a bad diagnosis but this is true with this color on a panel.
if it is a worth while set and you want to restore it theres few options one is replacement trough your waranty

the another is having the screen replaced by a service center this is to costly and rarely done by them they would advise you to get another set. at a retail price a screen replacement is as much or even more than the tv itself.

finally you may search online listings for a servicable tv same model and exchange the parts .
the third option is the best if your waranty is expired.

good luck hope this helps

happy holidays.

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.

You need to adjust the panel voltages, adjust the VS voltage to around 186 volts, if that doesn't change it then adjust the V-Scan voltage down, turn the unit on and apply a video source to it, and while adjusting the voltages look at the screen and you should be abe to watch the video noise fade out.
