Love all the videos! I’m a collector of vintage car audio & I’ve recently come across both a deh-p625 and a dex-p88 that both have no button lighting unless the illumination wire is connected to 12v... which of course dims the display. Anyone come across & remedy a similar issue?
An amazing find, and great tutorial. Just what I needed to restore the backlight on this now classic old radio! The bonus is that I also get to keep using the 6 CD autochanger as well! Brilliant, and many thanks.
Tenfo un stereo Pioneer-premier deh-p920r Jack muchos años guardado... funcionaba perfecto pero de a poco empezó cada vez a verce menos el display hasta que ya no se veía nada... que puede ser.. que opinas . Algo reparable o no?
pioneer deh-p780mp display faded white then nothing. Any suggestions are appreciated> Replaced ribbon cable and still nothing beyond normal button control
Holy moly this is fantastic!! I disassembled the complete unit and checked all connections and could not find the issue. I look up the problem on youtube and BAM this video showed up. Never, ever would i have suspected the problem to be in that small box. Thank u very much sir!!
Hello only this model have a external back light unit ? Or.its an adaptation y have a pioneer dehp835 r and the back light dont worck but it doest have an external unit
Kev, I have a similar model DEX P-78. My problem is that the backlighting works but is so dim it's only visible at night. Also, the external inverter buzzes. Any idea what might cause this?
Thank you for that, looks like an easy fix, I have the KEH-P8200RDS (Failed Backlight), KEH-P9200RDS (Just failed after install) and the DEQ-9200 (Still Working), so will get to work on those, I did buy the replacement brighter Fluorescent Displays to replaced the old original ones from an ebay seller. Thank you again, Spot on!
My Sherwood amplifier RV-7050R the right channel is not working, l experienced also shut off the amplifier and it won't give a loud sounds for both channels, please tell me what the problem is
Hi Kevin it's Steve again I made a mistake it's a Clarion Pro Audio One of the purple ones I just wanted to correct that with you on my last message I just sent you so it's not a Sony it's the Clarion but all the numbers are the same. APA 4200 G 50 x 4 Clarion Pro Audio. Hope to hear from you soon with my dilemma! To point me in the right direction on what to do with this gem. Thanks buddy.
Kev...does the CD Player and the Display need to be Plugged into the Motherboard to do Proper Troubleshooting due to Feedback Loops, etc.? I been Tracing Circuits without them Connected.
I know this video was 4 years ago but I just want to know where to hook up the illumination wire from aftermarket stereo? I can't seem to find the illumination wire on the car harness.
Hi hope you well. Have you ever fixed a indash radio? The 7" motorized screen? I have an issue where the radio shorts out as soon as you connect the positive wire and led light goes on to show power but it doesn't switch on al all. Do you know what that fault could be?
Hi, I have a pioneer deh 4600bt and the lcd works but it is not lit. I do not have a external power box like the one you opened and repaired. Where do I look for the component that powers the lcd backlight?
Good day! I have the old tape which consists of two consoles pioneer carrozzeria keh-p33 and cds-P33. There is a problem that the analyzer screen does not work on the disk player. Say, is it really to fix? Or the screen only change? The analyzer tracks must run on the disk player, and the screen is silent. The discs play normally, the buttons glow, the screen does not work.
Hi Kev I have a Sony 4 channel one of the older Pro Audio AP a4200 G 50 x 4. So this is the deal years ago I bought it brand new installed it properly used it for a couple months and it went off on safety this unit has a built-in fan! Just to let you know! I paid a decent amount of money for it back then so I unhooked it and shook it and I could hear something inside very small like a resistor rattling around inside anyway! I was upset and wanted to send it back so I put it back in the original box and got another amp from a friend and long story short it ended up in my attic for years. It always crossed my mind to want to get it repaired! Like I said it's got no time on it it's like brand new! Do you do outside work? Is it something I could possibly send to you to have it repaired correctly I really would love to have it back so I can use it on my highs on my latest stereo system then I'm putting in my Suburban I've got a lot of high-end gear pretty high-end gear to install and I would really love to be able to have this amp as one of my highs amps again. Please if you could get back to me and let me know if you could help me with this issue I'm very good with wiring and pretty handy with a soldering gun. I'm a CB and a ham radio operator so I've always been involved with electronics so it's not foreign stuff to me LOL it would be wonderful if I could get a response from you to help me with this situation thank you very much. I've been watching all your videos! Very impressive. I really appreciate a reply when you could get a chance. Thank you so much I look forward to hearing from you. Kevin. S Howard White.
No but that should be something easy to find where it is not getting power. Check all solder connections. Sony is notorious for having them. Check around the high heat areas like regulators and power transistors. You should be able to trace power from connector and see where it stops in the circuits.
Hello!!I recently got a Pioneer KEH-P8600R but the backlight of my screen is very dim.Tried another screen and it wasnt that dim.Is there a remedy in order to restore its brightness?
Unfortunately, by this time a lot of these units have suffered burnout of the EL strip inside the face. Your only option there is to attempt to make a new EL panel with one of the EL panel kits available out there. I've got a Sony XR-C900 with a bad EL panel in it's face. I know it's the EL panel because I swapped it on one of my other C900's and I get the same result. If I Iook closely I can see the dot matrix display working. One of these days I'll try one of those kits myself. Make sure the kit is one that allows you to cut down the size of the panel, as they are typically much bigger than you need.
Some of those are EL backlit displays, they weren't fluorescent but LCD with EL pad instead of LED, and they did also make OEL displays on some models also, it's just rare to see one, they only made them for a while
Google. That is the only source most people have. You might be able to find specific hard to find ones in forums pertaining to the repair of said device.

As i remember from my Keh-P5400 in the 90's, you have to manually select that function from the menu. When the memory erases, you have to do it again.

Um probably not the cd player but the screen you might have to, to turn it on.
I know this video was 4 years ago but I just want to know where to hook up the illumination wire from aftermarket stereo? I can't seem to find the illumination wire on the car harness.

Do you repair for people ? I have something needing repair

My FM transmitter fried my stereo. It stopped displaying
Ever work on a Sony CDX 4090 AM/FM Car Stereo Receiver w/CD. Mine is Totally Dead. BTW...I have the Service Manual.
No but that should be something easy to find where it is not getting power. Check all solder connections. Sony is notorious for having them. Check around the high heat areas like regulators and power transistors. You should be able to trace power from connector and see where it stops in the circuits.
I have a Dual brand with no backlight.
On rare occasions if below 30 degrees it will work
I wonder if bad connection on the board itself...?
Shame the green colour can’t turn orange
resolder joints is a good idea for vintage audio
I’ve seen many people ask without reply which probably means you don’t, but do you repair radios? I have a 90’s radio that I need looked at.
I am not taking any side work on at the moment due to Covid.

Can you service deq9200
pioneer 5090 dish play on karke dikhyo
kev how much would it cost for u to fix my mtx thunder 250x
Wow fluroescent backlight, that's old
It is not flourescent, it is an Electroluminescent Panel (EL). It requires an AC source, which is the metal box--it is an inverter.
super video
I've got the exact same issue. Watching now.
Hello brother I have same model player can you tell me how I can on the aux function
Dude, take your radio off, press the F button few seconds and then active The Aux function
Hey is there any way I can contact you about fixing a Rockville amp that I have?????
Contact me @g_jones64 on instagram
Gosh! That's kind of shady, really. Cannot think of a reason they couldn't make that part of the circuitry FIT INSIDE THE FREAKIN' CHASSIS.
I don't think It had to do with space. I think that they made it external to keep HF noise out of the deck from the inverter.
Exactly right.
bhai apka mobile number do
where have you been mate? been craving a new video. Cheers
Been busy with work and some home projects. UA-cam doesn't pay the bills. I didn't have much to show lately.
Kev31779 hey are you still working with pioneer components
Which site u does get them diagrams buddy
The google site. Where ever I can download them from. It's a hunt.
Nice video Kev, do you have any on a weak CD eject fix?
Nathan Zbinden Thanks Nathan, I'll give that a shot.
LCD backlight? High voltage? That's a fluorescent display.
Your right. I don't know what I was thinking. Today was so hot I think I lost my marbles.
No worries, thanks for sharing, and good idea to freeze the board, cheaper than cooling spray cans.
Some of those are EL backlit displays, they weren't fluorescent but LCD with EL pad instead of LED, and they did also make OEL displays on some models also, it's just rare to see one, they only made them for a while
Definitely an EL display, A flourescent display doesn't require high voltage AC, it would have no need for the inverter.
where does one get service manuals?
Google. That is the only source most people have. You might be able to find specific hard to find ones in forums pertaining to the repair of said device.
Thanks
