Biggles- hats off to you. Researched this fault yesterday evening after being a bit baffled by the --.-- appearing on standby. Watched PCRowan's excellent video and got stuck in this morning. I used Isopropyl Alcohol (IPA) as it is 99+% pure. There were 2 what looked like scorch marks on the back of the PCB under the crystal/capacitor area which cleaned off easily. All back together and working perfectly. Thank you.

All back together and working perfectly. Thank you.Glad that my efforts are still proving useful. Coincidentally a secretary at work had the clock problem last week but then it started working again, she thinks it's fixed, but it isn't.
Are you sure they were scorch marks and not felt tip pen as I have seen, I'd worry if they were scorch marks. 
For anyone doing the repair I would now advise using ordinary household meths as the cleaning agent available from B&Q and the like as it seems that surgical spirit can contain other stuff depending on where you buy it from. IPA, as you have used, is also going to do the job perfectly well. I will update the instructions one of these days.

I've just returned from holiday to find my 9200 clock has died,
I suppose it had to happen sometime.

I had this problem too and followed the advice along with the you tube video which was very useful. I used a steret(medical antiseptic wipe) - the ones they wipe your arm with before they jab you!
They are soaked in isopropyl alcohol and if you ask the pharmacist they will either give you one or sell you a few they are a couple of pence each.
The bonus is that cut into strips they work really well getting into the small places and are absorbent so soak up the nasty.| Tue 11 Nov 2014 17:50:16 #44 | -
It worked! I have to admit that I didn't feel confident about doing the job myself so I asked a friendly PC engineer (russel@desktopdirect.co). For the cost of a couple of cotton buds and a dab of surgical spirit (plus a pint for Russel) I've saved myself having to buy a new PVR. Be patient, the clock didn't reset itself straightaway so I thought the fix hadn't worked but next time I went back into the room, the clock was displaying as it should. Thanks Biggles!

Anyone know if there is a similar issue with the 9150? Despite the lack of a clock! I assume it still has an RTC circuit? It's just that some symptoms resemble those in a newly acquired 9150 that generally seems perfect. Full epg, responsive, you can record live programmes and play back, buffer etc.
But when you try timer record (from standby or while on) the prog will not record, and the record schedule is wiped. When trying from standby, it lights up, outputs audio and responds to the remote. No video till power is cycled though.
I tried another AV drive, same result. No visible power supply ageing (bulging or leaky capacitors). No signal or multiple transmitter issues. Drives formatted and defaults selected.
I know these boxes are even older than this thread, but I love them as radio recorders. I still haven't found a current box that equals their versatility and usability for audio.

It will definitely have an RTC circuit, so there's every chance that it's prone to the same problem.
Note that the capacitors used in the PSU will probably show no physical signs of failure.

.....In the 9200 the RTC is updated from the broadcast channel when the machine is ON so I expect the 9150 to be the same although the RTC circuit may be different. The fact that your 9150 doesn't do a timer record when ON suggests the problem lies elsewhere. You say the record schedule is wiped, this is a known problem of recent years with the 9300 and probably the 9150. Are other settings in the machine set back to defaults, 9300 owners have reported the machines appear to have had a Default Setting.

Trying to achieve a timer recording.
