SOURCE: PLASMA DISPLAY STARTING UP. PLEASE WAIT

Un plug the power to the Plasma Screen and also to the Media Receiver for ten minutes. Disconnect the off the air antennas both A and B. After ten minutes plug in the plasma screen then the media receiver and turn on wi the remote control. You should now be back in operation. I was.
Also It may not be a bad digital tuner. The TV Guide feature is active even when the zip code is set to all 0s so if you have an over the air antenna attached the TV will look for the TV Guide info and if it can not find it because of a weak signal or the chanel it is tuned to does not carry that information the TV thinks that tuner does not work which triggers the 12 flashes. Also on power up the gray box with the waring message "Plasma Display Starting Up, Please Wait" appears and the screen is blank.

SOURCE: Samsung Model: HP-R4262 42" Plasma Problem, pink pixelation/ghosting

Wow, I've been an installer and salesman in the consumer electronics industry since before the first plasma TV came out (Phillips 42" and Fujitsu 42" in 1996) and this is the first time I've ever seen that kind of an answer. "Take this to a repairman and he can add more plasma" what is the repairman a doctor. If it were that easy no one would ever have to upgrade or replace their screens. You can't add more plasma to a screen, if you don't believe me call Samsung and ask them for yourself like I did. I was actually so dumbfounded by your answer that I called a tech friend of mine at Samsung and asked him, his answer; "does this guy work for you?" I told him no and he said, "I was going to tell you to fire him because that's the dumbest thing I've ever heard anyone tell a customer".
What you need to do is take you plasma TV to an AUTHORIZED Samsung dealer/repair shop and inquire about the hazing/ghosting problem with them.

SOURCE: LG PLASMA TV WITH COLOURED LINES OVER SCREEN

I have the exact same problem with my 42" LG plasma which is about 3 yrs old. Turned it on one morning and had verticle lines all over it with only the sound playing.

SOURCE: Philips 42" Flat Screen Plasma - blinking red light 7 times - HELP please!

I had the same issue with 2 of these sets. It ended up being 2 capacitors were bad on the power supply. They are located towards the bottom of the board, you can visually see they were buldging and leaking slightly. I replaced them with 2 I salvaged out of an old computer (of same values) and the tv works as it did before.

SOURCE: LG flat panel plasma with red line

I had the same problem and fixed it by replacing the control board. It's a little nerve wracking, but required only simple hand tools. If you'd like to see detailed pictures of the repair check out my blog.

My SAMSUNG PPM42M6H screen has horizontal grainy lines at the top of screen measuring about 7 inches and from right to left. Lower half seems OK. What should be done or replaced?


Check the ribbon cables in side the TV that connect to the panel. They are the left side looking at the back. Make sure they are all seated propporly. If that does not fix, then your Upper Y Buffer board needs to be replaced.

I think it's screen burn image retention very grainy mainly red is it worth replacing the screen


No it would not be feasible to replace the display panel. It will cost as much as a new set.

I have a 50 inch samsung plasma tv that i think


You would need to purchase a complete new screen as it is not practical or economic to have this done. I would suspect your fault could be a poor connection from the buffer board to that section of the screen or most likely, as you state, the screen is at fault. It is now just as reasonable to buy a new TV than to have the screen replaced

Tring to find a samsung pn58a550 plasma screen replacement,my screen is broken. I was tring to find where to buy one.


I've never seen a source for replacment LCD or plasma screens for TVs. Effectively the screen is like the chassis of a car; you can buy everything except that as a repair part.

Even if it were available, the cost of the part would be very close to the cost of an entire TV set. Your best bet is to buy the same model with a blown power supply and take that part from yours to make a whole TV.

Samsung plasma R4272, sound, but no image on


Sounds like an X or Y drive board. They are the heart beat for driving the plasma display. Without them both you won't see anything.

Green noise on all black images on my SAMSUNG LN LCD TV screen


I had a similar problem with my LG plasma. I used the Image Sticking Minimization
(Pixel Orbitor, White Wash, and Inversion) feature which is designed to prevent image burn in and ghosting. This ISM feature may be available on the Samsung or any other brand under a different name. I activated the "white wash" option for about 30 mins, the screen turns white and somehow the pixels get reset. The green noise disappeared after that.

I hope this helps. Phezbuster

Image is grany every time tv is cold.


I had the same problem. Except mine never got better after the tv warmed up. I fortunately I still have my manufacturers warranty and Samsung sent a guy out within a few days. He replaced a few parts which really didn't do anything. However what he did that was interesting was on two circuit boards. One on the mid left and the other on the mid right. Apparently there is a nob or something he tweaked on each panel that cleared the grainy image right up. What he told me was that the it is basically pixels that are not turning off in sync. adjusting the two circuit boards syncs the pixels to turn on and off at the same time.
