It sounds like an Intergrated Circuit (IC) has fried. Even on a good day, this is not something you can attack at home. As a tech (and as an owner of that model samsung), I'd need a map & tools to know what's going on. Your best bet in this situation is to contact Samsung and let them recommend an authorized service center in your area. Sorry I can't be of more help, but this is a rather serious problem.

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.

My Panasonic PT LC76U has horizontal pixelated lines. See image at this link http://abigproduction.us/_images/panasonic.jpg


you need to check:
the Vga cables if the image shown is that from a computer
firstly check if the Panasonic logo comes ok in the beginning
if ok then try connecting a laptop directly thru a short patch cable to the computer port of the projector[i am assuming that the projector has been installed to the ceiling]
if this works ok , then the projector is fine!
you need to figure out the problem with the vga cabling and switchers if any of them are used!

Blue line Ghost Image on Panasonic Projection TV


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} This set uses two Stk-392-110 convergence IC chips; both need to be replaced along with any of the 2.2. ohm light blue resistors around them; a bad resistor will be white in the middle; You can buy both for less than 13 dollars plus shipping on Ebay.

The chips are located on metal heat sinks with fins and are side by side. They are black(about 2 inches wide by 1 1/2 tall) and should have the STK-392-110 number printed on them in white.

Depending on your level of skill at this kind of work you may be able to do it yourself---if you need step by step instructions contact me---I have them in Microsoft word---start to finish repair including what you will need to do it.

If you are not able to do the repair yourself now is the slow time of year for TV repair shops----It should be fixable right in your home and the repair takes about an hour--I have done hundreds of these sets--some shops charge 300-400 but I do lots of them for 200-250 total cost. Make sure whoever you get changes BOTH of the chips!

Shop around and if they say "needs to go to shop" keep looking; any good tech can do this right in your home.

I do this here for free so if this helps you give me a vote here. If you need direct help contact me.

Panasonic PT-AE900u no image


may i know now what is the age of your projector. have you done replacing the lamp of the unit before.

Lamp life varies by manufacturer and projector type. Lamp life also depends on the projector's environment: air flow, clean air, and also on the level of usage. Check the user's manual or specification pages for your projector to determine the exact lamp life.

You will have two of the STK392-110's in the set so a good idea to replace both. The reason is one of the IC's is dedicated to RED horizontal and vertical and then GREEN horizontal, the other is dedicated to the BLUE horizontal and vertical and then the GREEN vertical. These are the best place to start for ghosting in the colors.

Skt IC and Capicitor??


You need to replace both STKs. They are pretty obvious to find in the unit. They are normally mounted to the same heat sink and will typically be about 3 inches long each, maybe 2 or so high...Front should read something like STK350-120
