On the bottom right side of the screen it is sayin life expactancy 17 hours

Defective LCD panel, not worth to repair.

The cost of getting this plasma fixed is not costwise compared to getting a new TV. I recommend NOT to get another plasma but get either an LCD or LED for the best quality compared with price. Plasma parts can be quite expensive especially for a 10 year old model or may not be available.

Push the main control knob (right side of the unit) either up or down, until the Kenwood's display screen shows "Clk Adj." Press the center of the control knob for about a second to enter the clock-setting mode.

2 Push the main control knob either up or down to set the Kenwood's hour display. Stop when the correct hour shows on the screen.

3 Push the main control knob to either the right or left to adjust the minute display. Stop when the correct hour shows on the screen.

4 Press the "Menu" button located in the bottom-left corner to save the changes you made to the clock. This returns you to the main menu

try tightening top thread tension.

What has happened is part of your back lighting circuitry has gone out. Yes it is repairable but can cost most of what a replacement monitor will cost these days. Check that out before spending the money. If the problem is only in the back lighting circuit then expect to spend about $100 for a replacement board.

LCD monitors lifespan depends on the quality. Normal use and you should get 2-3 years of reliable service minimum. The display itself is good for about 4000 or so hours of use or more. The problems that show up are always (well 99.99% of the time) are back lighting problems like you have experienced. You should turn it off by the switch when not using it as every hour it runs the screen save is an hour of usable life. Heat is not good for it so if your computer gets the dust cleaned out to keep it cool do the monitor at the same time. Once a year at least more if you smoke use gas heat and have pets.

Tube monitors have a much longer life but you have the size weight and poorer display to go with them. If you have to go back to a tube monitor don't go back to your 14 ask around and you should be able to get a 17 or 19 crt for free. Or expect to pay no more than $10-20 for one.

As you probably know, these settings are made in the monitor setup, not through the computer. Monitor settings vary a lot, so it would be hard to even give a generic answer, but for sure you have several buttons either on the bottom or side of your monitor. Keep trying to push any of these (Left to Right or Top to Bottom) (except the on/off button) until you get a setup popup screen. On some models it jumps right up, on others you may have to hold in for a second or so. Then the next menu is from one of the other buttons. Usually there will be two buttons for + and - for adjustment and also for one screen to the next.

Im having the same problem and from wut I am reading in alot of diff places the screen is going bad or has cracked from rapid temp change is the most popular answer I have recived, as for a fix check ebay and buy a new one...I found some for as cheaps a $98 and some change and I have already taken mine apart to see how hard it will be to replace...its pretty simple...there are 6 rubber feet on the screen bezal remove them and keep them face up so the sticky stuff dont get anything on them...next there are 6 screws under each one of the rubber feet remove them...pull the bezal off gentaly so u dont break it...next there are 4 screws onthe sides of the screen itself remove them...next remove the flat wire and the backlight wires from the screen and there ya go all apart...to put it back together reverse the steps. :D...

and I know this post is just over a year old but I figured since no one else has posted a fix, I would just in case either he/she still has the same problem or even if some one else has this problem... well good luck

Your laptop screen has a thin ribbon connecting the screen to the mainboard. after upening and closing your screem these pins sometimes breaks causeings streaks in your screen. My compaq note book has to be resoldered because of a lose connection on back for power. your gonna want to get that fixed before you fry your board. costs about 50 bucks for an hours work to get that solderd. It could be linked to your flikering issue..

that is the screen burned out. if still have a warranty return to company and get a return/exchange.

It is due to logic board , component defect.
