my replay TV 5504 may have finally died - I've had the cover off a few times in the past 10 or so years I've had it in service but last night I think it might have died.

I took it out of service last night (unplugged it last night - I was watching a recording that started to stutter and after the 3rd time in about a 1 1/2 hours it wouldn't recover - tried holding the power button for reboot - the blue light came on but no onscreen. I then pulled the plug waited about 10 minutes then plugged back it - big spark at the outlet - blue light no onscreen messages and would not reboot with power button so I pulled the plug and called it a night).

this evening I got it out of the cabinet where it is kept - took the cover off then using compressed air blew all the dust out. when I plugged it in the hard drive spins up - but the fan did not come on - tried the reboot (but its not connected to a tv or network) the blue light went out then when I released the button it came back on - still no fan and I can hear the hard drive spinning. - weird thing is the fan started spinning about a 1/2 hour later (maybe an hour). when the fan wasn't spinning I recorded the voltages as:

Color: Y Y R O O B B B B B Gr Bl
Value: 2.9 2.9 33.7 2.5 2.5 0 0 0 0 0 12 4.9

I took another reading when the fan came on and found the Y = 3.05 v now - I thought after reboot it turned itself off - but the blue light is still on - I am going to hook it back to the network and tv to check if recovery has occurred - unless I am missing something

thanks for the reply - i reconnected it last night (after the post) since i heard the fan start i thought it might finally be booting. Initially there was nothing on the screen - and the fan was not running (I had to unplug when i moved from my troubleshooting area back to its 'real' home in a different room). I walked away after several minutes. A while later (less than an hour) i came back and noted that the blue light wa off and the red light was on - it lives! - but then when i tuned to the channel no video - i got to thinking and then realized that I had reversed the coax connections when i was hooking it back up.

so now its working but i am concerned about the power supply - has anyone built a dc to dc conversion using a laptop power supply as a source then using adjustable dc to dc chips to create the voltages? anyone know the nominal power required?

What you described will work theoretically but it will take too much time and effort. Just replace the bad caps and your rtv will be like new again.
