Keep in mind that the HD-PVR power supply may have a flawed power supply (capacitor issue). This may be causing failed recordings.

Thanks to both of you. To be more forthcoming I think I fried my box by using the wrong adaptor. I wish it was a "that's what she said" but I'm afraid I'm being literal.

Follow up Question

So, if I wanted to test my PVR (lots of blue screen problems etc and I am at my wits end) to determine if it is the Power Supply, are there any tests I can do with a meter to tell me if it is a problem.

Also, if I am going to put another Power Supply on, do I need to have the exact specs or would something like a 5.0v DC 1.0 Amp power supply work (I suspect not). What about a 5.0V 3Amp supply - would that likley be ok?

If not, I will try and hunt down one that is an exact match.

A power supply that has higher amps should be OK. The voltage and polarity should match exactly. The type of power supply should also match. Don't use a transformer block instead of a regulated switching block or vice versa.

Everybody should be careful with these pieces of junk. It turned out to be way to easy to fry my PVR.. it's not like I jammed in the wrong size barrel or something. I'm pretty angry about it.

If it's not obviously identified, putting on a sticker, etching, or otherwise identifying what equipment the adapter is for, when you first get it, can be helpful for when the adapter becomes separated from the equipment. If every adapter in your house has an indication of what it's for, then it's harder to make a mistake.

Also, when you get new equipment, if it doesn't have what voltage, current, AC or DC, and polarity of the connector (if DC) that it requires written on it, then you should mark it on it yourself, from what's on the adapter, in case the adapter gets lost and you need to replace it.

Linksys AD52A

Hey

like many others I have lost my adapter but I found a (Linksys AD52A) in a box I just check the spec and they look similat to the Original but I like to check with you first

Model # : M1-10s05
AC Input: 100-120 VAC
47.-63Hz 0.5A
DC Output: 5.0VDC 2.0A

Polarity: + on tip (Center)

Should I try it, they say " Use only the power supply provided! " so i'm a little scared to mess it up !

Thanks for your help !

spock999,

It looks like a match, other than it's only for 100-120V input. If the tip fits properly, it should work fine.

Also, make sure it's the same type of power supply. There are basically two types, unregulated current limiting transformer and regulated switching power supply. They are not interchangeable.

There's no problem using a regulated supply (with the correct voltage and minimum current rating) in place of an unregulated one.

The opposite is not always, but sometimes, true. It depends on the design of the equipment that it powers.

With regards to spock999's question, I did a web search for the M1-10s05 adaptor he specified, to verify that it was regulated, before saying "go for it".
