Question about Toshiba 42HP66 42 in. LCD Television
It happens in all types of input. How serious it is? How we can fix it? Thanks
Hello to all that have Red or Green pixels in the dark areas of any given picture on your plasma screen. I can help your fix your plasma TV. All that needs to be done is an adjustment on the Y sustain board. You will need to remove the stand and the back cover from the TV. Then you'll want to reinstall the stand so that you can set the TV in the up right position. Then hook a dvd player up to the TV and put a movie in and push play. Once you get to where you have a picture on the screen that has a dark image on the screen and you can see the Red or Green pixels push the pause bottom on the DVD player. Know you what to locate your Y sus board. It is the board that is going to be on the Left side of the TV if you are looking at the TV from the back side with the back cover off! If you are not sure what board is the Y sus then please feel free to give me a call! I will guide you to the Y sus board! 1-503-432-9904 Ask for Dave! Once you have found the Y sus you will need to look closely at the board and you will find some Blue/Yellow adjusters on the board! One will say setup and the other will say setdn next to it. Do not touch any of the other adjusters on the Y sus other then the two that I have mentioned above. If you do you could end up damaging your y sus! So once you have located the two adjuster on the Y sus with setup and setdn next to them you will need to take a felt tip pin and make a mark on the top of both the adjusters so the you'll know where the factory setting is just in case you need to start over! start with the setdn! turn it counter clock wise if there is no improvement then turn it clock wise! if there is no improvement then put it back to the factory setting and try the same adjustment to the setup adjuster. You will need to have some one help you while you do this adjustment to the Y sus because the TV needs to be powered on while making the adjustment and thus you will need to pay attention to where you are sticking the screw driver because you do not want to shock the poop out of your self! So find some one that can watch the screen for you while you make the adjustments to the Y sus! If you feel like your unsure about anything regarding this advice I'm posting please feel free to give me a call I will be more then happy to answer any questions you may have. Ask for Dave @ 1-503-432-9904 / firstname.lastname@example.org

Had the same red ghosting issue with my Toshiba 42HP66 plasma. I went to the retailer I purchased it from who went into a litany of stories that ranged from Y boards to new plasma panels. I contacted a local independant repair guy who had helped with an old Toshiba tube unit a while back, he said let me come "adjust" that out. He did just that, pulled all the wiring connections off, removed back, turned it on with no antena (the red ghosting was verry apparent with some very distinct burn-in graphics) he adjusted it out! No new panels, parts, just an adjustment. Charged $75 paid him $100 was so happy to have a hi def pic back. JS

Slightly adjusting the Setup and Setdown Pots (Little blue square thingys with a Yello center for you non techie types) on the Ysus board totally eliminated the red sparkles I had after I replaced the Ysus card. The set now has a great image.

Try going into the service mode and turning down the red drive. The problem is the red pixels fireing on their own on the black background This TV has major problems mine has the same problem they should recall this model! But they wont. I had mine for just a year and the red was there since the begining and now its worse. I bought a new TV from costco and the warranty is for 2 years and with AMEX they add another year. 3 total. The new set is 1080p with faster chips and LCD for 1199 90 day return
