4. Lamp life is dependent hours and the number of on/off cycles. Dust build up and where the set is used enters in to the equation also. Many EWs' don't cover consumables.

These sets are not without their faults, but if that is the only issue you had to deal with, I would think twice about selling it.

The lamps are not getting very many hours on them. I can run and check but I know the first one blew with 3858 hours. I'd bet the next one didn't even last 2k. This latest one lasted less than that as I just put it in August. Its in a pretty open area, the only wall or enclosure is behind it. I dunno, I think we're gonna try limping along with the new bulb and hoping for the best again.

Did you get any liquid on the bulb when you replaced it?

Did you ever clean the lens in your light engine?

I wouldn't know where to begin on cleaning a lens on a light engine.

My issue was never resolved and it was only a problem when routing it through my Denon 308 as well. Another thing to try is replacing the HDMI cable. If it is not sending a good signal it can have that issue.

It gets to a point the digital tuners memory gets wiped out after you manually delete hundreds of encrypted sub channels over a period of time. Trying to directly access any of those wiped out 'in the clear' digital channels will fail. The only solution is a full rescan. This is due to the set adding channels on it's own (only digital sub channels). Has anyone found a solution for this? I assume it is due to TVGOS causing the set to scan all available channels (for some unknown reason) even when a host is acquired and active.

In case you don't know what SDV is;

Couple of contradictions in your post. First of all SDV is Switched Digital Video and the music channels are usually all (70+) sub-channels of one non-SDV channel (frequency). i.e. channels 102.101 - 102.171

Second, encrypted sub channels and in the clear channels are two different things.

It's the Mits set and TVGOS causing your problems

Where are you "manually deleting hundreds of encrypted sub channels"? Most likely in the TVGOS channel editor.

My Mits did add channels on it's own (to the Mits channel memory and the TVGOS channel lineup) as TVGOS did it's scanning.

Musical channels as in musical chairs, the ones that they keep changing around.Not really, since they are all digital sub channels and each one occupies space has a ID. It's the encrypted SDV channels that are the problem as stated.I'm more than aware of this.The channels that are being added are in the sets tuner memory. This has nothing to do with TVGOS. There is no change there. The deletion is under 'channels' in the TVs' menu.But, that is only during the initial phase where the system is acquiring data. After the host channel is ID'ed, there shouldn't be any additional scanning since it knows what/where the host is unless the data stream has stopped.
BUT, the set still seems to 'scan' even when the above conditions have been met. Many times, it stops on cable 12 which is my other local 'host' even though cable 3 has been flagged as the 'good host.

After the 1st scan (other than the music channels), there were around 70 'encripted' channels that had to be deleted. The next morning, 55 more were added and had to be deleted. The next day there were 180 more. That evening an additional 70 showed. All of these are between physical channel 83 and 90, apparently the ones they use for SDV.

Are you in Fast on or Low Pwr. mode?
It sounds as your MSO is using SDV which is the other part of the problem as it is here.

The fact you aren't using TVGOS probably is the reason as I'm reasonable sure that is the culprit though my Sony DVR (TVGOS is the core of the device) doesn't do this. It also seems to ignore 99% of the encrypted channels which might be the reason no additional channels are seen.

BTW, when I called Mits, I got the usual "This is the first time we have heard of this" reply.
If that was the case then that would mean no one uses TVGOS, or has SDV on their cable TV provider and/or uses Low Power mode (that shuts down the tuner section among others).

Will it matter?
Should it matter?
