KC, I was wondering if you think a voltage of 11.7 on this TV converters board 12v leg (see photo below) is far enough off (or not far enough off) to blame my HDTV converter box problem on a bad power from the power supply board?

I've got no clue how far off the voltage can be but the other two (5v & 3.3v) legs are rhe correct voltage.

Thanks
Dan

info

Whats the problem:

  • The front panel indicator light is red (should go orange)

  • It does not turn on.



Indicator light colors:

  • red = initial set-up (30 seconds)

  • orange = standby mode (off)

  • green = power on (on)





A web search pops up repair techs calling it a common problem with cm-7000 and means a bad power board. (bad caps) But who knows...

PS:) I see what you mean about your camera being a sweet deal now that I finally got around to replacing mine.

Wow! The Canon PowerShot A4000IS for $79.00 at Bestbuy sure was a sweat deal. 8)

doubtful it's the voltage level but crap caps would cause it to drop and the unfiltered/under-filered DC power could be causing problems, it is certainly where I would start.

Thanks KC.

Now if I can just find something for this last cap (400v 22uf) nobody seems to have on local shelfs I'll replace them all and see if I get lucky.

Ya and they call that the medium (M1) resolution. Cracks me up.

Blink detection seems pretty amazing too.
