Try plugging in another known working monitor and see what happens. That will tell you whether the issue is with the monitor or your HP. And do not go to HP for assistance since they will not do squat for you - horrible support and not deserving of business.

SOURCE: No power in my Daewoo Monitor

Hi, Youo have zeroed in on the problem area. It looks like a power supply problem. More often than not, there is a fuse inside. If you would venture to open the unit up, do a visual check on the fuse. If it is busted: 1. Clean - no burnt/scorching/black marks inside the glass tube, then you can simply replace and hopefully the unit will be operational; 2. Dark smudges - or small burnt metal pellets inside the glass tube, then it is possible that you have other defective components that caused the fuse to blow. Normal components that are known to go bad are the big capacitor and or the power transistor regulator. Most current designs uses a switch mode power supply where your mains AC voltage is converted to DC that powers a circuit that eventually produces a lower DC voltage say 12VDC for use of the monitor. Should you venture a DIY (do-it-yourself), pls remember safety precautions when working with powered electronics. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.

Our three year ol Samsung TV has dark horizontal lines across the top of bottom of the screen. It is getting worse

Welcome to fixYa!

When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.

The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.

If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.

now if you can replace them your welcome but i wont suggest that , cause you may break it more....!

any ways do comment if it helped you in any manner!

There is horizontal line come in TFT in last 2 yr i ask the dealer he told that its bcoz some resister short now after another line come in my TFT whats the problem? and notice that this problem come after...

You may have failing TFT (Thin Film Transistor, each pixel on the screen is driven by one transistor, so there are 100 of thousands on the LCD panel
) or bad connection or failing T-CON board.
See pictures here:
It will usually get worst with more lines as time goes by. New panel will be needed.

Click the Menu button and use the '+' & '-' signs to select restore factory settings. Check if you get the same line in the BIOS screen, if so then you would need a replacement.
