TFT screen blanks periodically
Hi,
I recently bought a Dell 19" tft monitor. I noticed after using it for a while it would periodically blank for several seconds, then return to normal. This weekend however, it blanked and the only way to resolve it was to switch off the monitor for 20 minutes. It did this 3 times on Saturday. When it does this, the monitor is still receiving a signal from the PC, but the screen is completely black. Any ideas what could be causing the problem here? As it's intermittent, I want to avoid sending it back to the supplier, only for them to say they can't reproduce the problem. Are there any diagnostics I can run on the monitor myself? Thanks. Andrew. |
