You may take a strong flashlight and place it against the dark areas of the screen and look around the edge of the light. If you can see an image moving around, it is still being 'displayed' on the entire screen.
If its still there, it looks like an Inverter/CCFT problem. If the image is 'gone' or compressed into a single 'line' it may be the LCD controller (TCON) with a 'heat' or intermittent problem.
You may try a fan blowing on the vents on the TV to see it runs longer without going bad.

Black vertical line


This seems to be a problem with some older panels. If you are prepared to tackle the problem yourself then try the following.
WARNING there are some very high voltages within the TV which can be LETHAL so the greatest of care should be taken.

With the back of the TV removed, use a hair dryer and apply warm air to all the ribbon cables in turn until you find the one which causes the fault to disappear. Now turn your attention to the faulty ribbon and remake the connections as necessary.

Monitor goes black - green light stays on


My screen is black, why do I not have a picture?
Answer Antenna is not hooked up to television.
  • Make sure that the antenna cable is correctly connected to the television. If it doesn't work there appears to be no signal.
Problem is caused by television broadcast
  1. Push 'INFO' button.
  2. If the screen shows channel number (1, 2, 3, etc) try another channel. Not all channels broadcast at all times.
  3. You may have a signal problem. Contact cable provider or local broadcaster regarding the specific channel.
Television is in EXT or SIDE mode, and there is no external source provided, so screen mute (black screen) is activated.
  1. Push NEXT SOURCE button on the remote.
  2. On the screen appears all sorces.
  3. Press the UP button to switch to the TV mode.
If you are using an accessory device (DVD, DVR, or VCR), be sure the device is on and running.
Blank screen when connecting to the accessory (DVD, STB, PC) device via HDMI to HDMI.

Answer
  • Make sure the cable is well connected .
  • To check which connection is selected, Press the i+ button on the remote control.
  1. When you see Blue mute / blank screen and the i+ display does not indicate any video resolution indication then there is no valid signal detected.
    • Make sure the HDMI output of the accessory is valid by changing the video output resolution to a resolution which the TV can handle.
  2. When you see a blank screen and the i+ display shows a video resolution indication then the connection is correct.
    • The blank screen is caused by the accessory device and not by the TV.
    • To detect and remedy the problem caused by the accessory device, check the instruction manual of this device.
  3. If the problem remains : reselect the HDMI external source input by changing to the other HDMI input and back to the connected HDMI :
    1. Press AV on the remote
    2. Press up and then ok
    3. Press AV again
    4. Press down and ok
    5. The compatibility check process between TV and accessory device will start over again.
  4. Reset (switch off and back on) the TV and also reset the accessory device.

Red,green and blue lines across screen


I f these lines are slightly diagonal and they all showed up at the same time. you probaly have an open resistor in the ABL circuit. since your set is 13 yrs old, I would not put a penny into it.
You might take the front grill cover off and the panel behind it and find the little black box with 6 little controls 3 are for focus 3 are for screen turn the screen ones ever so slightly counter clock wise. the control in the middle is the green screen adjustment. If the green line goes away try the one labeled r for red and b for blue.

Vertical color lines


I had the same thing happen to me this morning. I turned on the TV and it had colored vertical lines through the whole screen. I called Sony and they had me unplug the TV for about 15 minutes. This solved the problem. They said the boards just needed to be reset. It fixed the problem and I am happy with my Sony once again.

Red, green, and blue rectangular "chads" or squares across top of screen


Hi there, this is easy thing to fix. Its LDV cable. This is the Cable which goes from the main board on to the screen. Un plug the cable from the screen side., then push the cable back. Make sure cable sits in .

This will sort all the problems with the picture,i.e colour problem , picutre squring up and many more things.
