Toshiba Plasma TV Green and Pink (Diffusion?) Problem

I have had my 42" plasma TV for about 13 months. All of a sudden, especially when watching cable tv parts of the screen keep turing florecent Green or red. I tried searching online and the only term that seemed close to this problem was "diffusion". It seems to be getting progressively worse and seems to apear mostly on skin tones and faces (envision overlaying the bright green matrix color over someones face with a similar texture). What could be causing this and how can i fix it?
Thanks in advance.

    I have the Toshiba 42HP66 and it is about 14 months old. It started having a problem with a florescent green or red rash appearing on the faces of people.
    In addition to that I have noticed random red sparkles on all inputs when the screen is black.

    Have a Toshiba 42HP66. When it was 11 months old we had PCB assembly replaced under warranty because of red sparkles. Noticed the sparkles returned again after 6 months, Toshiba refused to do anything because it was out of warranty. At 24 months lost the picture on the TV, called Toshiba in hopes they would cover the repair or replace the TV. We brought it to a repair center & they say the Y-sus needs replacing. Toshiba offered to pay for the parts & diagnosis but not the labor. It's $500 ($200 of which is labor). Do we have a lemon or is this a common problem? We expected a $2,000 TV to last many years.

    I have the red spots showing up on the darker areas of the screen. The symptom is most noticeable during power up as the "Please Wait" message appears. The spots are mostly at the upper and lower portions of the screen.

Only 18 months old, quit all of a sudden. Powers up but has no picture/no sound. Found a blown 4ah fuse on the ysus board. Swapped fuse and powered it up. the green light came on for a few seconds and went out. a few seconds later the red light went out also.If i unplug the ysus board the set will stay powered up. Any suggestions?

I could be wrong but sounds like your plasma display is going bad. What is your model number?

    If this is the case it would cost too much to fix. You could buy a new one cheaper or just as much.

Panasonic TC-P42U1 plasma. Lost it's vivid colors basic color is black and white and green and blue if tint color tone etc. Is turned up. However a blue ray video plays with full color. Could it be a lose...

I have an old Toshiba TV and was going to replace it with a new plasma because it has suddenly (the week of July 19, 2010) lost color. It has only green and blue tint. Changing the "tint" on the menu didn't help. The color comes and goes relative to nothing that I can measure, such as how long it is turned on, etc. Reading other complaints from owners of Plasmas, I am thinking it is cable related. I have Charter Cable. Playing a DVD, I have to readjust the tint back to normal. Hope this info gives clues.

Very light colored verticle (1" wide) ribbon on LG 42" Plasma TV

The TV is design for 16:9 format. The bars appear when the TV off showing that the TV has been watching under channels which is have 4:3 format for long time. The screen was burn out because no sweepping to those area. This is not critical problem but you can do nothing to fix it. To eliminate it a bit you shoud read the manual, I believe it has mentioned how to roll or sweep the screen. For plasma TV, if you keep watching 4:3 channels fomat, you shoud do it one a month within 30'. Good luck

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

Onece the plasma heats up it shrinks a little, i think the cause is that you are low on plasma, so when i heats it shrinks and since the plasma cycles, the area low on plasma wil move slowly around the screen, take this to a repairman and more plasma can be added to it.

This is called diffusion, it is caused when the power supply voltages do not match what the plasma panel requires. Unfortunantly this is not something you should do yourself, high voltage danger and possible damage to the tv if you are not very experienced with this repair. A technician can however read the voltages and adjust them to specifications and this will get rid of the dreaded red dot diffusion. Very common in samsungs but not that expensive of a repair. Hope this helps.

Lg plasma tv 42 px5d

Most times this can be corrected by the correct alignment of the diffusion. The unfortunate part is that will require a tech that knows how to set all of the power supply voltages and then align the diffusion pots on the ysus pwb. This could mean a defective ysus bd. but most times the alignment will correct this problem.

LG 42in plasma - Green dots on HDMI channel

The diffusion is slightly out of adjusment. This timing adjustment is difficult and on a single scan LG plasma the proper operation requires voltage settings first, then a scope to finalize the adjustment. I have good luck with this alignment by eye but have had alot of practice. This will require taking the back off and a person with the technical background to set this alignment properly. Sorry no easy fix.

Coloured Pixels in or around black areas when watching TV

This is know as a diffusion issue. Most times this can be corrected with some minor alignment on the pots on the YSUS pwb. Sometimes the YSUS pwb has failed and will need to be replaced.
