Hello everyone. Although this is my first post as a new member, I have followed your forum now for a few years. Been very grateful for the wealth of knowledge on here.
That being said, I was hoping to revisit the HDVR2 tuner 2 pixelization issue. I have a SDDVR-80 that has provided many years of faithful service. Like others, it developed the tuner 2 issue a while back. Disconnecting s-video and replacing/adding the power supply capacitors helped, but the problem persists. It's bad enough now that a few channels will cause a restart. I am aware of the option to add a capacitor to the motherboard, but am hesitant to do so. Besides not being confident in my soldering skills, I'm afraid it might eventually cause other damage if the underlying defect (likely the power supply) is not fixed as well.
This leads to my questions:
First, has anyone tried replacing all of the capacitors on the power supply to see if that will fix the problem instead of just the two mentioned in the instructables article?
Does the tuner 2 problem only effect series 2 units? I.E. if I were to switch to an HR10-250 or an R10 will I be ok? (I have both of those as spares)
Has anyone measured the voltages on the ribbon cable of a known good power supply (or off a repair manual) to see if we could adapt a PC power supply to replace the aging original units? I realize it won't fit in the case, but at this point I wouldn't care.
Thanks in advance for any input or advise.
