If there has been a change in firmware for these models we don't know about it.
So, as I understand,
Here is my understanding based on reading HLS threads.
this set has history of issues such as 'collapsing light tunnels',
I don't know if a HL-S7178 has been reported to have a shadow caused by a "collapsing light tunnel" in this thread, but it hasn't been reported in the thread dedicated to the problem. Most of the HLS sets reported have been "87" models with a couple of "88" models showing up. That doesn't mean that it couldn't happen, but only that there are no reports at this time. Far fewer HL-S7178 models have been sold. The total reports in the shadow thread for two model years (HLR and HLS) is about 60 at this point in time. I'm sure Samsung has sold several hundred thousand sets in that two year period.
service menu settings being reset when the set loses power or someone goes into service menu
User Menu settings are, by design, reset to default values whenever the SM is entered. That's true of all HLS models. I don't recall the exact incident that you are referring to, but I expect that it was a rare occurence. I read all the Samsung 1080p DLP HLS threads and I don't recall it being a problem for HLS sets in general.
dnie turning on by itself....
I don't recall this one either as a "problem" for HLS sets. If it was a common failure it should be showing up in the main ("87" and "88") owner's thread.
I'd like to buy it, but it kind of makes me nervous, considering the money that it costs.
The shadow (light tunnel) problem is serious, but all indications are that Samsung is taking care of it. It's the only problem that has generated it's own thread.Shadow Thread Summary
Samsung DLP sets seem to have more owners that report being bothered by pincushion bowing of 4x3 images than other RPTV brands. The bowing has to be greater than 1/4" for Samsung to take action.
Samsung DLP sets have had some power supply noise that can be heard when the set is in standby mode. It's an easy repair under warranty.
I skipped the HLM and HLN models because I felt like you do now. Anyone who buys any of these microchip technology sets, and doesn't live close to a good service provider may have a hard time if they need repairs. That is a situation that contributes a lot of the horror stories that you find in owner's threads regardless of the brand name.
