We were watching tv when we heard a pop, sparks came out the top & screen went blank. Removed the back, no visible damage, blue power light and red standby light are on. Tried to reset trap switch, blue & red lights still on. Any ideas?

Re: Pioneer plasma PDP5070 HD TV
Look at PSU, X and Y boards and Y buffers closely. If you heard a pop and there were sparks then something is going to be visibly damaged somewhere.
Good quality pics of all boards would help. -
Re: Pioneer plasma PDP5070 HD TV
We can't get good pics so we took out the main power board, no visible damage, no burn marks on front or back, all capacitors look in tact, but one has a black dot that's not consistent with the rest.Comment

Re: Pioneer plasma PDP5070 HD TV
Its not just caps that can pop. Diodes, fet's, Vr's and resistors can fail with a pop.
Check buffer boards and the ribbon cables going to the panel for burn marks or other damage.
If there were sparks, something had to let them out.Comment

Hello out there in Badcap land.
I have a Pioneer plasma that gave me the dreaded 8 red blink and shutdown, I have been trying to trace the failure points. On my last inspection while replacing a Y Sustain Board I noticed on the original and replacement board some missing solder, the points of connection
are from the Digital Address Board and the Buffer Boards. I have included the pictures, should I resolder these points or are they unsoldered intentionally? Any help would be much appreciated.
Thank you

Pioneer Pro-FHD1 Elite. Failure to power on.
I'm new to this awesome forum, and have been reading like mad, but have not seen the answer to my challenge.
We bought this Panasonic plasma monitor 16 years ago and it has never been serviced, so all parts are original, and the unit has never malfunctioned -- until about a month ago. The system fails to power on. At first (a month ago) this happened rarely. We learned to unplug for a few minutes to drain the caps, then re-plug, and the monitor would start normally. Now, we plug-in, turn on the main power switch, and the... -
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 -
Has anyone had any experience with with pioneer plasma panels, this one is in an NEC PX-42XR4G and it powers up for around ten seconds then goes into standby with a red led on digital board flashing six times and refuses to power up !...02-24-2020, 09:55 AM
