TH-42pw5 Monitor with 5th of screen missing

I aquired this monitor with no history of the thing. Switches on ok but has a fith of the screen missing and this then causes interference to spread out at least half way across the screen. The black part also has coloured bars running vertically, which change depending on the picture viewed. It just flickers by it self sometimes which makes me think it is a connection problem. The right side of the screen is fine with a clear picture. One forum i have read states it might be the screen that needs replacing but I think (hope) it is one of the boards. If any more info on this is required, I will give as much as i can. I have opened the back and found that a ribbon cable has been removed and not been replaced on the lower right C1 board, second from right. I plugged it in with no change to the problem. Please help.

Flat screen has gone black but sound is fine

Suggest that you borrow a monitor from someone and try it on your system. If it works , you may have a defective backlight on your monitor , which means that you may want to replace the monitor. If the replacement monitor also is black , you probably have a video output problem , which would require repair of your computer.

Troubleshooting Flat Panel Monitor issues.

Screen is blank and power indicator is off

The monitor is possibly not receiving power. Perform the following steps to fix the problem:
  1. Ensure that the electrical outlet and the monitor are both switched on.
  2. Check that the power cord is firmly plugged into the electrical outlet and the power supply unit.
  3. If the power cord has a removable fuse, replace it.
  4. Try another power cord.
  5. Try another electrical outlet.
  6. Check the power connection at the back of the panel.
Screen is blank and power indicator is steady green

Brightness and Contrast may be too low. Adjust the brightness and contrast using the On-screen display controls (OSD) by selecting the button
Screen is blank and power indicator is steady amber

The monitor is in the Power Management Standby state. The power management feature is invoked when the computer recognizes that you have not used your mouse or keyboard for a user-definable period. Perform the following steps to bring monitor out of the power management state:
  1. Press any key on the keyboard or move the mouse to restore operation.
  2. Check the Power Management software on your computer.
  3. flatpnlmont12.jpgPress the (OK) key to switch between analog and digital mode. If the panel is the wrong mode for the signal being provided, the monitor appears to go into sleep mode.

Display mode of the computer is outside the range of the monitor. The display mode the monitor uses is controlled by your computer. Therefore, you should refer to your computer's documentation for details on how to change display modes.

The image size, position and shape may change when the display mode changes. This is normal and the image can be readjusted using the IMAGE SETUP and the monitor controls.

Note: Unlike CRT monitors, which requires a high refresh rate to minimize flicker, TFT technology is inherently flicker-free. If possible, configure your computer for 1600 x 1200 addressability at 60Hz vertical refresh rate.

Use the following table as a guideline and reconfigure your computer to use a supported display mode. The highest resolution (for example, 1600 x 1200) produces the optimal output, but limitations of your monitor may prohibit this setting. Adjust the addressability mode until an image appears.

CHECK SIGNAL CABLE" message is shown and power indicator is steady amber.

The monitor is not receiving a video signal. Perform the following steps to fix the problem:
  1. Check that the signal cable is firmly connected to your computer
  2. Check that no pins are bent in the signal cable connector.
There are noises in the video signal. The IMAGE SETUP function is used to adjust the level of noise in the video signal which causes horizontal lines or areas where the image appears to be unstable and jitters or shimmers. This can be done automatically or manually.
Note: It is not applicable to digital input.
Use the image setup fix the problem:
  1. flatpnlmont6.jpgSelect (Image Setup) menu in the OSD.

  2. Select Manual to adjust CLOCK/PHASE settings.
Image appears to be discolored

The color setting may be incorrect. Perform the following steps to adjust the color settings:
  1. flatpnlmont8.jpgSelect (Image Properties) from the OSD menu.
  2. flatpnlmont9.jpgSelect (Color Properties) to adjust the color mode you find most comfortable or fine tune the colors using the Custom menu.
A few dots are missing, discolored, or inappropriately lighted

A small number missing, discolored, or lighted dots may be present on the screen, which is an intrinsic characteristic of the TFT LCD technology and is not an LCD defect.
Using On-Screen display (OSD) controls
flatpnlmont12.jpgThe settings adjustable with the user controls are viewed through the OSD. Press the (OK) button to display the main OSD menu.
OSD main menu:

Note: The LCD monitor needs time to become thermally stable the first time you turn it on each day. Thus, to achieve more accurate adjustments for parameters, allow the LCD monitor to warm up (be on) for 15 minutes before making any screen adjustments

Losing TV picture, screen goes blank,

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

The screen is pink

I'm assuming that this a computer screen. If this is the case, try a new or different monitor lead it can be as simple as that. Then try your computer with a different monitor if the lead doesnt' fix the problem. If the screen is still pink with a different monitor you may need to replace your video card. If the different screen is OK on your computer, then it looks like your monitor needs to be either fixed or replaced. Hope this gives you a way forward.

Hannspree HF289H Black screen SIngle orange light once and completely unresponsive

There is two chance for theis problem. 1) there is missing voltage to the back light inverter boadr or 2) the back light inverer is faulty. Check the power supply volatge to the back light inverter board. Normally its 24v for all lcd back light inverters. If the power supply is ok then you have to replace the back light inverter board.

You can check is there is any picture on the lcd screen by the help of a tourch . light the tourch near to the lcd screen and wach the screen from different angel while the PC is in ON position.. in some angle you can see the shadow of picture if every thing else working fine except back light.

If so there is powersupply missing or back light iverter is faulty. You have to replace the back light inverter board with a new on because there is no repair possible with the board. Also the spares will very difficut to get.
