I have also have this problem with a lifestyle 28 system. Bose sent me a new cable then a software update. The problem remained, after contacting Bose and unplugging cables and powering down the system this solved the problem. However 2 days after and the problem has re-appeared. Back to square one. I should add that this is the second unit I have had the retailer exchanged the last one because of the same problem.

Honestly speaking you should probably not work on this unit yourself: "There are no user serviceable parts inside"
Even if you are an accomplished Electrical Engineer Bose will not provide the required schematics to troubleshoot and repair this unit.
Are you still undaunted . . . then if the case is the original LS-25 series, there is a hidden catch at the end of the cover furthest from the input connectors that needs to be rotated (until a plastic tab is sticking out), which you can do with a flat bladed screw driver, and you also need to remove a few screws from the bay where all of the connectors reside. Remove the two knobs from the side of the cover. Then hit the case with your fist at the far end (plastic tab) and the cover should then pop off. You may have to hit it hard, with an upward motion.
Note there is not going to be much you can do to fix this beyond replacing the fuse. (Note that the fuse may be soldered in.) The bass amplifier is op-amp based with discrete class G output stage and the twiddler amps are monolithics with discrete class G circuitry shared between several channels.
The power transformer has a thermal fuse in it as well which is not replaceable. If you play the unit loudly for long periods of time and it is not adequately ventilated it is possible for the thermal fuse to open - if this is the case you will definitely need to send it in for service.
When plugged in there are hazardous voltages present on the top PC board where the power connector is located, whether or not the unit is turned on.
Power switching is via a triac controlled by whichever front end you have CD-5? 12V should be present on the mini plug (tip I think, but might be ring) when the music center is on.
There is also offset detection circuitry that will latch the unit off should any output have more than a volt or so of offset.

Unfortunately, an 802 error is bad. That means hard drive (HDD) failure. This can happen to any hard disc drive, and there's no way to predict it and no way to fix it from home.
If you even try to troubleshoot it (reset etc), you could loose more data (music you've already stored to the system). If you try to access 'stored' music- the error will continue. Also, every time you turn the system off, it checks your HDD, and will probably cause the 802 or 801 errors to display again.
The "Format Unsupported" message may be related, but usually temporary. The 802 (and also 801) errors mean irreversible HDD damage so it doesn't matter.
Call Bose tech support immediately.. They can repair it for $165 and give a new 1 year warranty. And if it's already under warranty they will repair for free. In either case they will replace your HDD with a new one, and transfer any salvaged music files from your existing drive to the new drive.

I am quite sure that the indicator lights should be green. The blinking yellow likely indicates that there is no communication between the head and the audiomass. Verify that the connections are tight and then try powering off (unplugging) the system (both head and audiomass) for 30 seconds and then powering on again. That will often re-establish communications.

I recommend you stick with component cabling.
Having no picture at all generally suggests the V30 is trying a video mode your TV does not support:
