Re: Poor picture and tv blacks out
Make sure you have the TV connected correctly. If you have a cable box or satellite receiver and are connecting using an RF connection to the TV's antenna jack, you need to be on the right channel (usually 3, maybe 4 depending on the box setting). If you are connecting using A/V cables be sure you don't have a bad cable and that you're connecting to the proper jacks. If you are trying to pick up digital broadcasts off-the-air, you might need to adjust your antenna or put up an outdoor one. Signal strength is very important to digital reception.
If none of this solves your problem you may just have a defective TV. If it is really so new it will be covered by the manufacturer's warranty, and may still be in the store's return period. Call for service or exchange it.

Hello. It looks like problem is originated near buffer board/s. You can try to repair this but it is not recommended for untrained person. If you remove back cover of your TV on the left hand side you will find ribbon cables that connected to narrow and long buffer board (or two boards) with one end while other end goes inside PDP (Plasma Display Panel). Poor connection could be present on any side of that ribbon cables. You can try to "play" with ones that are visible and see if it will clear the picture while TV is turned on. But this is not safe, there is about 200V running on some boards so you have to be extremely careful. If poor connection is on the other side of the cable - than issue is impossible to fix without replacing whole panel. And this is more expensive than just buy a new TV. I would recommend let professional to take a look at it. Your health and life is not worth of any TV set out there. regards. Russ.
Does it happen on other inputs? If so, reset the tv, sat or cable box, unplug power and try again. Play a dvd. Does it happen on a dvd? If not, there is an issue with your cable source. If it shows on dvd too, contact your tv manufacturer. You need a repair.
Well first thing I would like you to try is unplugging the TV for an hour or more. At times this power reset will correct the problem. This TV is known for having issues with driver circuit of the screen. This will cause the problems the TV is having. This is not a repair that most consumers are capable of repairing. Poor solder connections are known to be the cause of black lines. This will require the bad solder connections be found and re soldered. Without testing there is no way to be sure this is the problem. I would expect this repair to cost $150 plus, depending on how long it takes to locate the poor solder connections and what is found to be out of specs. Please post comments if you need more help or information........
You may have got a bad unit but more likly it's your cable you are using I have found with the newer HD units the siganal has to be real clean coming in or you do get a distorted picture. Try changing out you cable lead for a good quality cable,
Is the onscreen menu just as distorted and are the lines across it or behind it? The pop you heard may have been a capacitor and since the TV is still powering on, it's the probably the video controller board that is on it's way out. If the onscreen menu looks fine, you maybe having a problem with the input board only so try a DVD that uses a different input and if it's poor, I would say the TV needs to have the input/output board service. If the OSD is distorted as well then it's definitely the video controller board and service is likely required.
TRY UNPLUGGING SET FOR A FEW MINUTES...PLUG IN LINE CORD WHILE HOLDING PRESSING POWER BUTTON..IF THIS DOES NOT WORK..CPU BOARD IS FAILING...P/N 667-L32K5N-56I...TRY CALLING MCM FOR PARTS AVAIL/PRICE...JOE ACE
I have a two and a half month old Sharp, LC-19SK24U-W. It was fantastic with fantasic, clear, beautifully colored picture until two weeks ago. All of a sudden, the picture starting getting darker and darker. Nothing had been adjusted from day one when I set up contrast, etc. This comes and goes but most of the time is an issue. I can make it a bit lighter but then it is so fuzzy and grainy it is a very poor picture. Also, while this began, one time the television turned itself off and then back on without a power surger or anything.
