Well thats simple, change out the control system! lol

Thanks everyone. Resolved.

Problem:Ir output was set too high. You may want to make a note of this if you max out your ir sensivity on every job like I do.

Solution: standard output setting from factory works well.

in 10+ years of installing MRF-350's I can count on one hand the number of times I had to adjust the outputs off of default....

I plan to remove the shell from an IR emitter and place the raw LED under the USB door. I might cut a wire pass out of the door's edge. The unit is mounted on a rack shelf and the wire will be difficult to see or disturb. Of course, this would make using the USB port more difficult, but it's not a problem in my installation.

I'm using IP control on this unit, however, it is a region free model and regions must be changed via IR and one must keep the quick start option OFF during region swaps. Routinely, the only use for IR in this case is for Power ON and one might need to poke around for discrete IR power commands. The RTI library cheats and uses toggles, labeled as ON and OFF.

Had a lot of saturation problems with early directv boxes.

I learned to max them out unless there were problems. Plus, it was much easier to see them flashing during the hunt to locate the ever-changing tv sensor.

I found this tread useful and helpful!

I was having issues controlling the Sony UBP-X800 using a Control 4 system (EA3 processor plus Halo Touch remote). The installer had placed the IR emitter (blaster) on the disc door near where Sony put the IR symbol and control of unit was inconsistent (e.g. worked about 70% of the time).

I moved the emitter from the right side of the disc door to the middle of the rocker switch as suggested in this thread and that seems to have solved the problem with inconsistent control. The middle of the rocker switch is is an awkward location for an emitter. I hope to get the control of my player switched over to IP control to achieve a neater install.

Or just open the player up and install the emitter inside.

LOL, you must not know how hard it is to open a Sony UBP-X800.
I actually damaged my personal one doing this when I 1st got it. I put it back together and it looks & works fine. But Sony made it difficult to get into this one with all the angled snap clips and hidden fasteners. I would never try this on a customer's unit.

Haven't touched one, so you're correct. Is there no IP control on these then?

The X800 and X800M2 are the same as far as the chassis goes with the hidden screw design. Also similar to the old X1000ES (that had an IR input port & RS232 however).
The X700 and X700/M come apart like every other player on the market with a few screws (easy).

I know some of the Sony UHD players had no IP control for some reason (baffles everyone as to why). Can't remember which ones did & didn't.

I don't sell the Sony disc players anymore after what seems to be a complete breakdown of any logical design. No auto Dolby Vision support (you have to go in a menu and manually engage it every time you play a disc that has it - even thou every other player on the market can do that) was just an unforgivably stupid screw up. As far as I know, they still have not fixed that to this day (it was a feature not a bug).
No one buys discs players anymore anyway. It has been years since I sold a disc player of any kind. I got rid of my Oppo a long time ago and the Sony X800 just sits in my rack unused year after year :(

How times change. I used to have a stack of entry level, and a stack of decent integra Blu-ray players in my storage unit. I always kept one on the truck, because at any service call there might be a dead player and an opportunity to sell a new one.

Then I started just keeping one model in my storage unit and on the truck. Still a stack of them. Then I got down to one in the storage unit, none on the truck. Now I sell maybe one a year.

I have to figure out what to do with the eight track tapes in the garage as well. Oh, and the near top of the line Pioneer cassette deck that needs major service. How times have changed.

There was a news article = This is the last year that Best Buy is going to carry physical discs. Starting in 2024, they will no longer be selling CD, DVD, Bluray, or UHD Bluray discs.
It is probably not long before we see the rest of the major retailers (that are still selling physical media) do this.

3 things:
1) Streaming has not gotten to the point of replacing the quality of physical media yet. This is especially true for customers that don't have access to fast enough internet.
2) You are at the whim of whatever is being provided to you. There has been 3x in the last month I thought of an old movie or TV show I wanted to watch and it was not available on ANY streaming platform (and I don't own it on disc).
3) Prices keep going up and you have to pay if you want to watch.

It is very sad that the whole "You will own nothing" movement is rolling right along, because the vast majority of the population just doesn't care. This is why we can't have nice things anymore.
