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: Which Replacement Power Board for LNT4665F Samsung LCD TV?

Howdy,
It would be a lot cheaper if you just replace the two caps that have gone bad. Just get a cheap solder pencil from the store and about an inch of solder and you are in business.
The Power Supply Board is the center Board (towards left) after you remove the back off the TV. Remove Board from TV with the 6-7 screws. Replace capacitors CM852 & CM853; 2200ufd 25volts.

Thaks for using FIXYA, BIG IRISH.

SOURCE: Not the capacitors, replaced in August.

Hello solidsnake55, my names Dave.

I Have worked on this model of TV many times! This model has a power supply that is a two in one! Meaning it is the mean power supply / inverter board! If you look at the top side of the power supply you will see that there are two wires that go to the back light of the TV one is light blue and the other is pink! I think! Anyway next to where they plug in to the power supply is the main inverter! it is square 2 1/2 inch's by 2 1/2 inch's. You will want to check all the solder joint to the inverter on the back side of the board! Theres a good chance that you have a bad solder joint and all you'll need to do is re-solder the bad joint to complete the repair! This is a common problem for this particular power supply!

If you need any other help with this repair or any other repair please feel free to contact me at www.pleasefixitdave.com You'll find all my contact info at this website!

We are a plasma / LCD repair shop in Portland, OR. We also sell factory replacement parts for Plasma & LCD type TVs! All the parts we sell are warranted not to be DOA (Dead On Arrival) with a full cash refund or replacement part! I also provide TV repair tech assistance!

Thank you!

IMAGE STAYS ON FOR AN LONG TIME


Sounds possibly like image retention. If you watch the same channels often any recurring text, logos, or graphics, especially white colored, can ghost on the screen.(playing the same videogame for a long period can also have the same effect) Watching other programs or channels will cause the ghosting to disappear.

To prevent image retention you need to activate the TVs anti image retention mode(Called ISM Method). On Zenith and LG (the manufacturer of Zenith T
s) plasma TVs open the TVs menu, select the Option section (picture of a briefcase with a wrench). Select ISM Method and change it to Orbiter, this is reccomended if you watch programs or channels (or play videogames) that have still images for long periods of time. It moves the image a little every couple minutes.

If watching others channels or programs doesn't make the image disappear, change the ISM Method to either Color Wash or White Wash (don't use White Wash frequently, it over excites the plasma gas and can shorten the life of your TV if overused) for a few minutes and then return to Orbiter.

We are getting ghost images and the color is not correct


I have red concave lines going across the screen, plus wording appears double like a ghosting effect, this is ongoing from the time the tv is turned on until it is turned off. This started 3 days ago. Is it time for a new tv, its 9 or 10 yrs old now.

Picture shifted and ghost image


Try using an input other than the tuner. I.e a DVD player or game system on the front inputs. If the picture looks OK on the other input, your tuner is damaged and will need replaced, if it looks bad also, try unplugging the TV for 5 minutes and then go through the setup process in the menus. If this fails seek a repair shop.
