Samsung LCD monitor slow to start up (Crystal aging?)

Get an ESR meter, and check all the caps in the monitor. You will most likely find some that are high in ESR.

As for having any proprietary parts for your monitor, they will be very difficult to find.

- it just sits there alternating its power light orange/green. Once sync is achieved it works fine.

I have the service manual / schematics and have been probing around the main PCB. I believe that the problem is that the monitor struggles to get past the point where the main GM5020 graphics processing IC measures incoming HSYNC/VSYNC frequencies and tries to match them to a mode that it supports. I'm hoping its not the GM5020 as that is a PBGA package so can't be replaced by hand.

I am wondering if the problem is that the crystal frequency has drifted as it ages - I see from the parts list that the crystal is unusually fine tolerance

Anyone had similar experience with crystals / Samsung monitors / GM5020 IC?

Anyone know of companies in the UK that can supply specific made-for-Samsung components? (The equivalent of partsearch.com in the US?)

All help appreciated,

Richard
