I have a Sharp LCD Monitor (LL-T17A4-B) that when turned on it flashes the image briefly and then the image goes off. It appeares the image is good except it lasts about 1/2 a second and them the images shuts down. Is this a common problem?

Thanks,
Clarence

Hi yes this is a common problem with both laptops and TFT monitors.

Most common problem is either the lamp's or the inverter but it can be caused by the main board.

That exactly symptom of our Sharp LCD(exact model number),No post for this.I suspect od the lcd screen.

Hi I have the same model with the exact same issue. But I have found that if i unplug all the lamps but one the image stays on longer. I talked to someone and he mentioned the ballast could be the promblem, But I don't know how to go about testing that. Any more suggestions would be appreciated.

Try to change electrolytic capacitors - they are known to get wet trough the time and their ESR grows. Use LOW-ESR 105°C types (for switching mode power supplies).
