- F06, F04 refer to the VHS carriage getting stuck mid-motion between the "run" (loaded) position and "eject" (unloaded) positions. If a VHS is jammed or failed to fully eject, this may be the reason why!

VHS Error Codes Decoded: Pg. 26 (section 7.2.1)
Carlos - just found your channel and this video. I have a DMV-EZ475V ( great unit for past 14 years) and the service manual is wonderful. After reset (holding power switch for 10 seconds), I get an F07 error code, but cannot find it in the service manual. Do you have any suggestions?
Thanks, Kevin
Hi Kevin,
I also cannot find any mention of F07 in the manual. Can you verify there is no VHS or DVD stuck in the machine and the VHS loading mechanism is in the full up position (pgs. 12 and 14 for descriptions of how)?
@@CarlosR_ Thank you for the fast reply - much appreciated. I confirmed that no VHS tape is stuck, the carriage is in the full up position, and no DVD is stuck. I reset the machine again this morning using both methods - hit reset button located behind DVD controls door and press & hold power button for 10 seconds. Now error code F60 comes up. Ouch. Probably a well documented electrolytic capacitor failure. Any other ideas?
@@CarlosR_ I opened up the box and DUST! Vacuumed it all out. I visually inspected the electrolytic caps and found no bulging or leakers. I also used isopropyl alcohol to clean the surface mount control board in case there were any "dust bridges" across and of the chip pads. Still getting the "F60 error code and from the service manual p17 - DVD module has not started; defect of digital PCB.
I do not want to mess with repairing a surface mount PCB. Any ideas on where to get a replacement board?
@@stollfamily3914 Alright, that was a smart thing to do. Capacitors can still fail/fall out of spec without "telling us" by bulging, busting, or leaking. Unfortunately it requires removing them from the circuit and testing them individually so we can't rule them out by visual inspection. It is sounding like either a issue with the powersupply to the DVD board or in fact an issue with the DVD board as F60 is telling us. But the diagnosis would require a multimeter at a minimum or ideally an oscilloscope to check the power supply rails.
One other thing to try is to unplug and replug all the cables inside the box in case there is a bad/loose/slightly corroded connection to any of the boards. Of course make sure to have the unit unplugged from the wall before doing this!
As for finding a replacement, eBay would probably be the best place to find the board/old unit with hopefully a different problem you could harvest the board from. One thing to keep in mind is, assuming the new DVD board is 100% functional, the problem may still exist if the problem lies in the power supply or elsewhere. In essence, this could be an additional trouble shooting step; just to forewarn you.
I appreciate your willingness and determination to fix this unit! I wish more people would take the time and effort to service/repair their equipment.
Can u share diagram of the connection and components
I have Panasonic EZ485V. Bought it new over a decade ago and stopped using it a few years into having it due to the disc drive tray wanting to close itself almost immediately 90% of the time I opened it which made putting discs in a pain.
Decided to use it again recently having forgotten about that issue and immediately remembered why I hated the device so much. No clue why it ever started doing it because it wasn't used all that much, probably started doing it after about 2 years of owning it.
Hi Carlos, thanks for making this video. I'm currently about halfway through replicating this repair, using an off the shelf L298N motor drive controller board.
Just to verify the points you show on the board, F(orward)In, R(everse)in, and Out1 & 2 are straightforward. For the other three points, I'm guessing LGND is ground, VCC is 5V and the one in the center that's only partially visible is the 12V supply?
Thanks again.
Hi @MarkGiannullo,
I believe that is correct. I don't remember exactly and the unit didn't belong to me so I don't have it here to open and double check. But two ways you could check are: 1. If you're comfortable connecting all of the boards out side of the chassis and powering the unit on, you could then take a measurement of that point with a multimeter and verify the presence of +12V. 2. Using the schematics and pcb diagrams, you could start at the +12V rail and follow the lines until you get to the area around this chip and then find a convenient place to solder your line to. I regret not taking a picture of the wires after they were soldered to the PCB because that would have made this clear. Good luck with the rest of the repair, and I hope it works! Please report back or maybe even put up a video of the result, I'd love to see it. Take care, Carlos.
I have one of these with the error F60. Any tips on how to fix these? I’ve done all the reset options but can’t figure out what other options there are.
On page 17 of the Service Manual (link in description), F60 indicates that the "DVD module has not been started". That could be due to a failure of the DVD control board (as suggested by the table) or a failure in the power supply; such as some of the capacitors wearing out. Or if you're lucky, a loose connection/cable between modules. So besides recommending the basics (unplugging, waiting, and re-plugging it in, or perform the resets as you mention), I'd need more information to make a judgement. For example, was the unit in storage and you just plugged it in to use it, or does it stay plugged in and idle 99.9% of the time? Was it dropped accidentally (or on purpose O.o)? Any information would be helpful. Try opening it and visually inspecting the parts and compare them with some of the pictures in the video. In particular the capacitors (around 4:30 in the video).
@@CarlosR_ Thanks for the reply! It was mostly sitting in a cabinet at my parents home. When I got it out, it wasn’t plugged in so it was most likely sitting like that for some time. I just opened it up and it’s VERY dusty and has some cobwebs. Definitely going to clean that out and hope that could fix it somehow, but we’ll see. Checking the capacitors, they all look in really good condition! I don’t see any broken parts or anything that could be damaged, but I need to check a little deeper in the machine. As far as being dropped, I have no idea. It’s definitely been through a few moves but it’s been usable since the last one.
@@gabathaelise1160 Okay, once you've cleaned all the dust out, try (with the unit unplugged from the wall) removing and reinstalling all of the cables that go to/from the DVD drive on both ends (where it connects to the DVD drive and where it plugs into the main circuit boards). The idea here is if there is some corrosion that has developed between the contacts of the cables, mechanically moving them could clear off the corrosion and restore proper contact. After that, try plugging the unit in and see if the error code returns (you may try resetting the codes first) It's a good sign the capacitors look good physically, but that doesn't totally exonerate them as they could be "on their way out" without having totally failed. But for now we'll assume they're okay. See if this helps at all but if not, we'll have to dig deeper.
My has a error code ho 7 on the dvd side / I have no pictures or sound on both video and dvd
Hi, Glad you were able to fix it. I have a panasonic dmr es30v. I remember that the DVD worked but the cassette did not. It won't accept the cassette. Can it be fixed with an external board like yours. stay well.

Hey carols i have Panasonic vcr nv-225 i buy it from cheap so i brought it home and plug in its eject tap after some seconds showing error f06 so i searched everywhere and found ur video but i didn't understand the whole connection i will talk it later after then i took deep cleaning pcb and macanism deep cleaning then i perfect reassamble and put it back and see same problem occurs so i show some videos tells its because faulty capacitor so replace some capacitor and switches then see same problem and i can't get it the same ic here in area so my question is i so what is the faults 1 campston motor 2 bad rubber belt or ic or capacitor? I really hope u could help me brother love ur video love from India
Hi Nayan,
Remove the top cover and rotate the Load/Unload motor (the silver DC motor on the right side of the VHS system) with your fingers so the VHS carriage is in the up position. It may be a little challenging since the motor is tucked between the circuit boards, but be patient and go slow, watching how the mechanism moves. When it's in the full up position (the metal carriage is up against the door you normally push the VHS tape in), plug in the unit and see if the F06 error has been cleared. F06 indicates the carriage that moves the VHS from the input slot down to the motor/read system is stuck in the middle of it's motion. By moving the carriage to the up position manually should allow the power-on self check to successfully complete. Let me know if you have any questions about those steps and I can try to describe the process further, otherwise please report the results of that test as they will determine the next steps. Cheers, from Maryland, USA!
@@CarlosR_ Carlos first of all thank you very much for ur kind reply i Appreciate your kindness ☺️ and yeah i been repair showing some videos on TH-cam its help me a lot and now its working fine otherwise i definitely try this thank you so so much Maryland is amazing and you the beautiful people thanks Carlos love and light namaste 👏
@@vintagelover3873 You are welcome! What ended up fixing the problem?
My Panasonic VCR no. NV-sd235 ER.F06
Credo che tu abbia fatto un'ottimo lavoro,l'unica cosa che non mi piace sono i filetti delle due viti che sporgono sul pannello posteriore,io avrei messo due viti filettate dall'esterno che bloccano la basetta del circuito con due dadi interni,cosi dall'esterno si vedono solo le due teste delle viti
Great video everything proven vhs movies VCR player VCR belts cleaning tapes everywhere online now days everything proven vhs tapes don't stop playing at all it's the people who stops playing it
