Troubleshooting Flat Panel Monitor issues. Screen is blank and power indicator...


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.
Screen is blank and power indicator is flashing green
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

Too dark sony model kv21gmr1


Warning: The following procedures should be done by an expert.
1.First step is to check the physical condition of the set.Before starting troubleshooting try to resolder the board and find any cold or loss solder.Then after plug the set and see if the filament of the tube glows.If not the trouble is in heater circuit.
2.After seeing the filament if it glows, check the CRT socket and open it.If you can see a sign of terminal decay such as greenish unwanted element on terminal surface,replace the CRT socket.
3.If replacement does remedy the problem check RGB drivers and resolder or replace jungle IC.
4.Try also to adjust the screen adjustment found in the flyback transformer.
5.Another possible cause is the vertical IC.Adjust the screen to full and see if their is a white horizontal line on the screen.If so the problem isin vertical circuit.

Closed caption


Manual Library you should find all you need here:
http://www.techlore.com/group/2/list_downloads
Just word search the manual for closed caption


if you can find this in your TV options I cut and pasted it from the manual, see the line with Closed caption settings see if yours matches, sorry about the formatting this furm post will not cut and paste properlyeach of the #'s below corosponds to the bold headings.

I also found this with the word search but it makes no sense to me sorry...

The HDR2002 has two microprocessors. The Microprocessor, 7001, on the SSB monitors the Keyboard and the Remote sensor during standby. This IC controls the Tuner, Video switching on the SSB, generates the consumer OSD. Pin 5 of 7001 monitors the Keyboard for a voltage change to generate a command. The Front Detect line on Pin 6 monitors the AV inputs on the Side Jack panel. If a problem develops, the Front Detect will go Low, preventing 7001 from receiving any commands. The Power Fail input on Pin 79 goes High if the set looses power while the set is On. Composite Video is fed to Pin 31 for Closed Caption decoding. Horizontal and Vertical sync on Pins 53 and 55 synchronize the OSD and Closed Captions display signals, which are output on Pins 46, 47, and 48. Fast Blanking for the OSD is output on Pin 52 There are three I2C busses on 7001. The Bus on Pins 78, 80, and 97 communicates with the MemoryIC 7012. This IC stores Customer setup information, Option codes, and Error codes. I2C busses, Sand F communicate with the Tuner on the PIP panel, and the ICs on the SSB. The S bus also controlsthe Tuner on the SSM and the Audio and Video switching on the SSM. Data lines on Pins 16 and 17communicate with the Microprocessor on the ACS module.

below is my general post about this TV, I'm not sure if any of its info will help but there are links to other info on this TV set... Good luck

Hello....
This problem is related to ABL control .
Trace ABL signal from Pin no 11 of flyback transformer.Mostlikely value for the resistor in abl line has gone high.First case reduse the G2 voltage and see if the unit works for long.
Second case its sure that its ABL problem.
