Replacing The Fuse in a Panasonic TAU TV


Sure, this is a standard definition TV, and sure it is a CRT, but I love this TV. It has served us well for around 7 years and I still enjoy watching it. I take good care of the tv, use good cables, and keep it pluged into a power conditioner. However, yesterday when i turned it on to attempt to watch a little True Blood, the tv did not respond at all. I pressed the power button and saw no lights, no buzz, no hum. I checked all the power connections and power strips  that i could but no matter what i tried, the TV was dead.

Attempting to repair a Chi Flatiron

The Chi Flat Iron is an expensive device. When my Wife’s Chi broke, a little web research showed that problems with the power cord seem like a pretty consistent complaint.

Full System Save

A Full system save on the AS / 400 is a system backup that captures the whole “hard drive” to tape so that a full restore can be performed if needed. To perform this backup the system must be put into a restricted state, which means that while it is running, there will be no connectivity to the system.

There are two steps involved in running the backup, 1: initialize the tape, and 2: schedule the backup. The process is described below.

Now, schedule the full system backup

Note, this full system backup can ONLY be scheduled from the terminal that is physically attached to the AS/400. You must be sitting in front of the AS/400 to schedule this backup. (This is also the reason that my screen shots are actual photographs… because I could not screen capture the session.)

Enter the command go backup
