Anyone know what the error code ER03 means
on a Technika DVR100

( VCR/DVD )

If anyone does use this bit of kit, then I would much appreciate a copy
of the manual, the one we have does not give any information on
obtaining an I/V curve.
I think the situation is complicated by the fact that Veeco seems to

From other posts it looks like APC UPSes eat the lead acid batteries
that are in them over a short period of time.

I need some advice here. My old Palm 3 is going to the garbage soon

the video input damaged the IC that deals with the color component of
the video signal.  I managed to replace the IC, restoring color to the

What is the story on the standard (small blue) USB keyboard? I have suddenly
got two in with one key on each not working and can't find a reference to
this on Google.
Is this a known problem?  Is there a simple cure such as unscrew the lower

My 87 year old granny has this TV. While playing with the remote she
inadvertently has caused the TV to go into a "sales floor mode" where its
tech info scrolls down the screen in multi colored array. This is driving
her nuts. I have unplugged the set for over one hour and tried ...
