Hello and many thanks to Biggles for his information.
The timer/clock failed on my 9200T as described.
Today I diligently followed Biggles instructions on how to clean the time clock board using standard chemists surgical spirit and a small fine brush. My guide to removing the board was an excellent YouTube video. I am a novice at this type of repair but I figured it was worth a try before buying a new card. It worked and the machine appears to function fully now. My advice is to have the video playing whilst repairing so as to be precise with every move then be patient, gentle and thorough with the cleaning process. It was surprisingly easy.
Thanks once again to Biggles for saving me money and giving me the satisfaction of repairing it myself.

.....Is this the You Tube video you refer to? I would advise dismantling the 9200 on a table/workbench etc. not on your knees as PCRowan does.
The maker of that video also doesn't realise the ribbon cable is in a ZIF socket - there is a small latch which releases/locks the cable.

I've just gone down in my estimation but I can blame it on old age eyesight and recovering from a foot operation at the time.
I always thought that replacing the ribbon cable was the trickiest bit of the whole procedure.

I'd just like to add that I had the same problem, and thanks to Biggles' clear instructions I cleaned the RTC card and my Humax 9200T has been working fine for a week now.

Same problem with silver machine 8 yrs old. Followed Biggles advice using surgical spirit with great success. Biggles you're a star - can't imagine how you came up with the solution!

Wow, this has fixed my silver 9200T too, thanks Biggles. I used white spirit to clean the board as this was all I had available. I suspect the contamination creates some stray capacitance or current leakage that kills the oscillator, it doesn't take much to kick a low-power crystal oscillator out of kilter.
My board has a continuous copper ground plane, not a mesh.

I'd like to add my thanks to Biggles for this one too. My 9200 has been back in working order for a week since I cleaned the board with isopropyl alcohol from an old tape head cleaning kit. I also brushed off loads of dust from the main PCB.

Thank you very much, got my humax working again for only the price of some surgical spirit!
