UBP-X800: UHDBUDecode.exe SOFTWARE FOR REPLACE OPTICAL UNIT

Thu, 13 Aug 2026 14:38:29 -0700

I have a Sony UBP-X800 which not read any disc, so I need to replace the optical unit, but in the SERVICE MANUAL says that in order to make the change first I need to take a picture of the Bar Code on the Optical Unit and load it into a software called " UHDBUDecode.exe " and save a text file, then save it into a USB and load that file into the UBP-X800 ub port....

I made a search on the web for the UHDBUDecode.exe software but it seems it doesn't exist or it isn't in any part of the Web, so I'm asking if someone could help me to find that software or if someone have it if could please share it, I hope someone can help me.

Thanks :)

TEAC CD receiver CR-H250 Unit makes a very loud grinding sound when switched on. Continues even when radio setting is selected. Had intermittent fault when playing CDS (stopped playing sporadically) before this noise began. Any advice happily received!

Logitech Z623 Speaker System: Volume knob causes right speaker to drop out

Thu, 13 Aug 2026 10:08:58 -0700

I suspect this is a general issue that could happen to any device with an analogue volume knob, because I feel like I've experienced this issue more than a few times in my life. But I created a device page for this anyway.

The right speaker cuts out entirely, but if I tap the volume knob, the sound comes back. The left speaker doesn't have an issue.

FWIW, the right speaker houses all the controls for the system, the power button, volume, and bass control, you may be able to tell from the image. The right speaker connects down to the bass speaker with some kind of data cable , and the bass speaker connects to power, and also the audio input.

I've read many pages on cleaning out volume "potentiometers" to clear up crackling, and while I do hear crackling when I rotate the knob, I was unable to clear up the crackling by repeatedly turning the knob back and forth, maybe more in depth cleaning is necessary.

I've actually got some contact cleaner, but haven't opened up the speaker to try and clean out the volume knob yet, I thought I'd ask first.

Mainly; I'm curious if a dirty potentiometer is known to cause just one speaker channel to drop out completely, or could this be another problem?

Logitech UE MegaBoom: UE Megaboom will not charge (light still flashing)

Wed, 12 Aug 2026 16:46:09 -0700

I haven't used the Megaboom for 6 months, took it out of storage and used it for the last couple of days while I was working outside (still had battery that lasted two days). Once it went flat, I plugged it in to charge overnight, the white light was flashing as normal. In the morning, I tried to turn it on and it said "Critical battery, please charge". While charging, if I try to turn it on, it just says "Charging, please wait". It still won't work no matter how long I leave it charging, though the white light is still flashing as normal. Is the battery toast? I did use it outside on a day with a lot of fog

Sony MZ-1: Won't accept or eject Minidisk

Wed, 12 Aug 2026 13:43:40 -0700

Hello,

This is the very first question of this device, so I will expect some typos, but not much.

My dad is allowing me to fix his Sony MZ-1, and I accepted it. It does not accept or eject any Minidisk, which I presume is linked to the locking mechanism. Is there anyone out there that is able to guide me on opening it up? All help is accepted (Except for self-advertisement, that is. We hate certain self-advertisement here.).

Many thanks,

Projector: Epson EB-675W Bulb does not power on

Wed, 12 Aug 2026 13:15:03 -0700

Epson EB 675W projector.

Blue power light when plugged in.

Press power button, blue power light stays on, blue status light starts blinking. Fan spins up normally, but bulb never lights up. Status light keeps blinking for about two minutes and then projector turns off, blue power light still lit. No reaction from any button press after initial power button press.

Have tried changing the bulb, no difference. Have had it open, removed and mounted the ballast board in another known good EB-475 I have, as they are practically the same. Ballast works fine. Power boards not identical, so can't try exchanging them.

I have done some more Research. All thermistors (temperature sensors) are Reading about the same resistance, 11.5k ohms. The Power supply seems to work properly, no bad caps or visible damage. Output voltage to the mainboard seems to work properly and Readings are consistent. The fans turn on and no fault lights when Power button pressed. Input voltage to ballast is 373V DC, which seems right. Tried changing ballast also the other way round from my other known good similar projector, and there is no change starting it With a known good ballast. Tried putting the bulb into the other projector, starts properly and lights up.

I’m really running out of ideas.

Had it been the safety switch, it should have cut all Power, not allowing the projector to start at all.

There is no voltage going to the bulb, so there is something in the Logic not letting it start.

I can not stop the projector again by pressing Power off two times, which would be the normal routine, which leads me to think the machine doesn’t start properly. Any ideas? Hard reset routines or computer diagnosis port would be helpful.
