That was amazing! Thank you for sharing your hard work! I have also repaired my own VCR recently but being an after 2000 model the lower and upper drum are one big replaceable component witch I just needed to pull it out and pop in place the new one. the only other thing I needed to do was to attach the drum motor witch sits on the top. I think that most VCR-s made after 2000 were intended to be easily repairable with as less adjustment as possible.
Hi i have a Panasonic VHS VCR, on SP the video is garbled, on LP, EP the picture is fine, tapes played on SP mode used to playback fine but now it doesn't what could be the issue. Thnx.
Excellent job! This is knowledge and skill that we need to preserve, thank you for making this video to share it. Do you just compare the old and new head under a microscope to find one with the correct gap width?
*Любой подобный ремонт обязательно нужно снимать на видеокамеру , чтобы потом в обратной последовательности можно было собрать до последнего винтика всё правильно* 👍
How about Hi-Fi adjustment after replacement, would that be ear and scope or more difficult? And afterwards the usual locking glue like for the a/c heads or a specific glue given its a moving part?
Hi Livinlifetothefullest2750 ! After head replacement , FM audio switching point also should be checked, if there is noise switching in Hi-Fi audio , please re-adjust again. To lock parts from moving, please use loctite.

Hello Misu how are you? Congratulations for your very instructive video and good quality and explanation. How do I get these heads? I'm in need of some.
Miso bro, I have a Panasonic VCR nv hd 620 whose head seems to have become disfunct due to wrong cleaning and wiping with cloth. Is a replacement head available in your city? I can pay online if it can be couriered to me in India. Pl advice.
Hi, I'm restoring a Hitachi VT-410 VCR and I noticed that one of the video head is broken. I found the upper cylinder replacement at a very cheap price, EUR 6.80, and I think to buy two of them and try to replace it. Is it really mandatory to use the comparator as you do on 8:43?
Thanks, is there a way to remove the head and still be able to play the tape without image. I'm working on a project and need to put a similar tape (not video/audio tape) in VHS spools and just play, FF, RR.
Hi Morteza Parkook ! If you use the original tape transport control and servo circuit board , it will not work when remove the head drum block because of no drum rotate detection. In this case , video heads don't matter much for play the tape without image and it is no need to remove the head chips on the head drum. If you use your re-built control circuit , you can remove the head drum block.
Hi rsuryase ! We can use Video Head Chips of one brand on other brands , but must ensure that they must be the same type , Ex : SP head , LP head , SP/LP head , Hi-Fi head , Erase head , each type has azimuth and azimuth- pieces, they must be correct position.
Now where can you get replacement video chip heads? The thing everyone must consider is that both the upper AND lower drum haven't worn down too much. The upper is dead easy but the lower drum the entrance/exits will ultimately determine the difference between the chips poking out of the drum too much. IT'S CRITICAL in operation that the tape uses that air between it and the drum surface to flow smoothly and the tape comes out of the machine 'undamaged' and not in fact using a worn surface and wearing or scratching the tape surface. It can be so easy to say the drum looks fine but also too easy to turn it into an instant cheese shredder and your precious tape is the victim and potentially unplayable.

Thank you for showing this and how you make the alignment on the single head! the FM packet from head A (changed head) is it near the same then the other head B but is the tiny difference in the FM packet the new head - in that case that it is new compare to the other head B? What for a head you're using for the head A? where did you know what is this for a head +6° or -6°? or is this the color that is on it? Thank you for this Video Thumbs up No.452 weakbit
Hello Weakbit ! There are many types of video head chips, their resistance and inductance is also different so the FM amplitude will also be different. We cannot find a replacement head that is the same as the original head, so after alignment , the FM amplitude between the changed head A and the original head B will not be exactly the same. The purpose of the alignment is to get the highest FM amplitude from the changed head. Video heads have positive and negative azimuth, and they have different color rules according to the manufacturer. According to experience, if the color pair is blue - green, then blue is negative, green is positive. If red-green pair, red is positive, green is negative. If green - yellow pair, then yellow is positive, green is negative. If blue - red pair, then red is positive, blue is negative. For example if the original pair (O) are "blue- green" , we can replace them with the new pair (N) : "green- red" that mean blue_O → green_N ; green_O → red_N (for reference) That is experience, may not be accurate as each manufacturer may be different. To be more certain, a microscope should be used to determine the azimuth angle.

Wow I didn't know VHS head drums require eccentricity adjustment like the early Betamax head disks. Does this also apply to other brands like JVC and Panasonic? Also it was nice to see a demonstration of video head dihedral adjustment! What's the tool called for doing dihedral adjustment (horizontal azimuth)?
Hi Fivos Sakellis ! This procedure can be applied to 80% of 70s, 80s, 90s common VCR models. Most of models produced after 2000 are often designed in "instant noodles style", which used 1 time and difficult to replace and align. To adjust the horizontal azimuth, I use an L-shaped eccentric stick. I bought this tool from a retired serviceman , I don't know its name or part number.
@@misu4602 Have you ever done dihedral adjustment on a Betamax video head? On the Betamax alignment tape, the monoscope section has the head switching point visible in the middle of the frame, and to adjust the horizontal azimuth, you look immediately below the switching point to see if the video fields split apart. The head disk on Beta VCRs has threaded holes and there are special conical-shaped screws that you put through the holes to shift the position of the head that way, instead of using an L-shaped key.
@@crashbandicoot4everr Betamax is not common in my country so I don't have experience in Betamax , I have never done dihedral adjustment in Betamax , I just fixed the locked drum problem.

Hi Aki san ! I'm from 越南 . Thanks for your interest in this work . For the best result in head replacement work , you could buy new video upper drum block to replace in your VCR, you will not have to do any delicate alignments but it is necessary to find right part number (please see in service manual of each model). If you can't buy right video upper drum block , you could do this work by replacing head chips (as this clip) , but this work need much delicate alignments. You need to buy new video head chips to do this work . Video head chips were sold in my country in the 90's as universal parts , they are general-purpose and can be compatible with most VCR models. I don't know their part number . I bought back the inventory of a electronic component seller .
