When I first attempt to power-up my Pioneer SX-750 receiver, it lights up but no sound. After it warms up for five minutes, or so, the audio comes on and the unit works fine. Recycling the power switch results in normal operation. What are my probable solutions?

Re: Pioneer SX-750 Power-Up
a dried out cap in the protection circut can do this as can improperly set bias or dc offset.Last edited by kc8adu; 07-27-2008, 07:59 AM.Comment

I'm starting to re-cap a Pioneer PL-X9 turntable, specifically the motor control board, because although everything tests out OK according to the service manual, the speed wavers slightly despite the quartz lock light remaining on. So, I've decided to re-cap that board since it's the cheapest next step...
Pioneer's passive component naming convention is clear to me. For example, CSZA R22M 35 is tantalum, radial leads, 0.22uF, 20%, 35V.
BUT there are two capacitors on the board which have actual Pioneer part numbers: PCL-042. I can tell they are 0.1uF, 16V but don't... -
Hi everyone,
I'm currently working on reviving a Yatour YT-M06 CD Changer Emulator module for use with a Pioneer 1 interface (specifically with a DEH-P5950IB head unit).
While the unit is recognized as a CD changer, none of the USB, SD, or AUX features respond, which leads me to believe the firmware may be corrupted or incompatible.
🔧 Details:- Model: YT-M06
- Interface: Pioneer 1
- MCU: Fujitsu MB89F202
- Goal: Find a valid .bin firmware file or memory dump from a working unit
I'm happy to attempt flashing, analyzing memory dumps, or doing hardware-level...07-15-2025, 12:26 AM -
Pioneer Kuro Pro 111FD 8 blink red LED.
I have been trying to solve the power-down 8-blink red LED problem with my Pioneer.
So far I have replaced the power supply board, and the digital assembly board, I have reconnected the ribbons to all boards, ensuring the connections are good. Even though the problem is the 8 red light error and not the more common 8 blue light error code, I had Kcrownie,
based in North Carolina replace the chips that cause the 8 blue LED problem (the main board and audio board) the plasma is still powering... -
I have an older Pioneer receiver (VSX-44) that's been dropping the HDMI output (black screen) for a few seconds every few minutes. Setup is HTPC -> Pioneer DVD HCMI in -> Pioneer HDMI out -> Samsung TV HDMI in, all with cheap HDMI cables that have never caused trouble before..
I initially found a lot of play in the receiver's HDMI inputs and output so I kind of squeezed them back into shape and they're making a tighter connection, but the problem persists.
And also, often, the HDMI will drop out in exactly the same way (black screen) just as my central air... -
This forum has been so useful to me and I thank all the people who have helped me in the past.
I'm now in need of some more assistance, I have purchased a Pioneer sg530 graphic equaliser to add to my Pioneer X-G7 hifi system. This equaliser was a factory option on this system but as this was purchased second hand I didn't get a user manual. Searching the internet has been fruitless, can anyone help with a schematic of how this should be wired into the system or possible a copy of the user manual.
Thanks
