Hi,
I recently got a Dell 2000FP LCD monitor. It still works fine but it has a known component temperature-related problem - if the monitor had been switched on for say 30 mins it cannot be switch off or on again, when removing the power (20v power supply) and plugging it in again it would get stuck in its boot-sequence or lock in standby mode. It works again after cooling down for an hours or so. I have read on some of the monitor repair forums that this standby problem is known problem caused by some of the SMD capacitors going high in ESR .
I have a few questions to fixing the problem
- how well do Capacitance Meters work?
- Would this meter do the job or can anyone recommend a good ESR meter?

- All of the caps are Aluminium Electrolytic - Surface Mount but some are harder to identify without a schematic, does anyone know of a good site to identify capacitors
Thanks
