My IR converted K20d has stopped playing ball

Just took my K20d out in the hotel room on a weekend away in Scotland and the bugger isn't playing ball...and a 2 week holiday coming up shortly as well. Deg nab it

No metering or focus. No lights in the view finder. The menu screens are available though both fully charged batteries I've tried are showing red. The LCD turns off when I half press the shutter button but as I've said, nothing comes alive in the viewfinder

Has anyone else experienced similar symptoms?

I have just googled K20D troubleshooting and found the following link http://www.pentaxforums.com/forums/6-pentax-dslr-discussion/54117-poll-k20d-free... I am not certain if this will help, but thought it worth suggesting

Whatever my issue is, it looks like faulty hardware. Decision now is whether to send it for repair when youre not certain of the cost OR look about converting my K5 which doesn't see a lot of action since the K3. I assume the K20d glass could be used

Anyone willing to offer advice?
