White screen


Hi.
Generally an all white screen scenario is caused by no signal from the monitors video board getting to the actual screen.
It could be as simple as a disconnected ribbon cable that mounts the two items.
It could also be a fuse on the back of the actual lcd screens circuit board. These fuses are usually labeled F1.
If you have a tester and the capabilities, in normal running mode the screen should be getting around 5 volts dc at this fuse.
The other problem could be a bad video board. These are not always repairable.

well it should be one of two things either you do not have a good connection to your monitor cables or you have a faulty video card. It would be the only thing that would cause this.

26" flat screen akai tv


Hello RJ13,

This may be a problem in the HV section of your TV. My question is do you have raster, or is the screen totally black? If you have raster then this is a video problem, if the screen is totally black then it is a HV problem. In either case if you do not have a background in electronics I would suggest that you take your TV to a qualified TV technician. If you do have a background you will need the following items:

A schematic diagram of your TV set to know where the test points are and to see what voltages and or signals should be at what point in your TV set
A multimeter to measure AC voltages. DC voltages, and Resistance when needed.
An Oscilloscope to measure signals that should be present in various sections of the TV as shown by the schematic.
A signal generator to create the proper input signal for testing.

These are the major tools needed, not to mention a soldering iron, and a de-soldering tool

I hope this helps you,

Thank you,

Shuttle83

This is a fairly common occurrence, typically due to signal loss. The longer the total cable run (monitor to computer connector) the less loss you will have. The longest KVM to computer cable I can use reliably these days is about 12-15? at 1024 x 768 at 32 bit color or 8? for 1280 x 1024 at 32 bit color. Things you can do to reduce loss: -Reduce the length of the total cable run. -Increase the quality of the cables used. I only use low loss cables now and have far fewer issues. -Change the video card, some cards can push a signal a longer distance that others. -Reduce the resolution/colors the video card displays. -Try a different monitor or if possible use a different (low loss) cable to connect the monitor to the KVM. Let us know how it turns out or if you have any other questions.
