Compaq 7540 screen is blurring and what is the reason behind that?


It could be EMI by the monitor, or it could just be failing. Try the following.
1. Do you have speakers or other electromagnetic sources (walkie-talkie, cell phones, etc.) sitting close to the monitor? If so, try moving them away from the monitor. They will effect how the electrons from the electron guns hit the color phosphors inside the monitor tube making the display blurry.
2. Try running a monitor diagnostic to check if the monitor is finally failing.
Post back how it works out.

If the OSD has display and after a min goes dark that monitor has 2 possible problem. 1. bad electrolytic capacitor from secondary power supply to inverter area or fault semiconductors around inverter area. 2. Bad CCFL or fluorescent lamp of lcd panel it may be reddish color.

Monitor Compaq Perisio 7540 (screen goes Dark) complicated


THERE MUST BE A PROBLEM WITH THE VIDEO PROCESSING CIRCUIT LOCATED AT A PCB CIRCUIT ATTACHED AT CRT BASE. THERE MUST BE SOME DRY SOLDER OR A FAULTY BASE CONNECTOR WHICH CONNECTS THIS CIRCUIT TO CRT.
YOU CAN ALSO TAKE A TRY JUST AFTER PRESSING THIS CIRCUIT FIRMLY TOWARDS CRT BASE.

Compaq 7540 colour looses red color


check the pin # 1 of video input cable { broken or Bent }
if it is ok then there must be a problem with the cable or RGB Processing Circuit { Normally Dry Soldering of a faulty IC in the circuit of CRT BASE} .
