i have a panasonic nv-hd640 wich i have been trying to fix i think the issue is similar i load a tape and it goes in and down thats it and makes a buzzing jamming noise ( i think from the loading motor) im trying to see if it could be anything mechanical but im not the best in terms of tech repair so yeah its sad because the unit i found is almost non used

Try using a Bristol wrench on the record knob instead of an Allen wrench. If the screw is an original, then that should do the trick. Thanks for sharing this video.

The hot line is Not the return line from the cooler. The hot fluid is the fluid that has not circulated to the cooler and is on the way to the cooler.

The 1B uses a dual voice coil and each are driven from one of the STKs ... IIFR

Thanks for the video. Is this some thing that a TV repair shop can fix for me?

Lol ........ those batteries will not produce enough amp your heater is drawing more amps than those batteries will produce wich causes all that heat

I think you missing the point or don't understand how it should be used!!!! Nothing will fix a badly desulfated battery. But if you got a relatively new battery & you use this unit on a regular basis, you will extend the battery life from 4 years to around 8 to 10 years, depending on usage.

My wife's two cats essentially require that I follow them around repairing and cleaning whatever they choose to destroy.

I wanna thank you for giving me the courage to finally repair it.

Hiya mate. You may have a distant memory of me from following you years ago 😊 Anyway....I've been in the construction trade for years & I still find it impossible to guestimate how long a install or job is gonna take. So now I always add extra days onto my initial ridiculous estimate 😂😂. Good to catch up, see you in the next one,😊

This is a very helpful video as I'm doing the very same job tomorrow. Tone arm barely moves. BTW If the arm doesn't or can't return to its stop; all the buttons on the front stop responding (except the Open/Close). This had me worried until I worked out the cause.

Looking great, though the dogs and cats are likely to be a little unhappy with the new smell.

I don't suppose you have any leads on where to get a new bottom element, mine snapped at the part where it's held in on the left hand end. I think the whole oven is a very bad design.

Could always use a bit of blue loctite

Model no of my Sony display protect hcd_gtr888

Thank you

Question when your testing the leds do you have the tv powered on or off?

Guy, you started off so well, talking us through, explaining things. Then about a third of the way in, it seems you lost patience. Everything sped up, explaining nothing. You had a superb instructional video going, then tanked. Too bad.

Please show us how to replace a composite jack with a component jack into an old CRT TV.

As a tech, I found that heavy cigarette tar was a problem at times, but it could be removed from the top surface of the lens, and sometimes the bottom surface of the lens and sensor depending on the model. Some units would come in smelling like an ashtray and were coated with a noticeable tar tint on the exterior. Surprisingly, what I found what was worse on rare occasion was a home where a humidifier was used. I verified this with customer contact. My theory is that the whiter talcum powder layer was more effective at scattering the laser beam focused on the sensor that uses multiple elements. The cleaning process was the same. I noted a couple of weeks ago here on this channel that the Sony/Samsung DVD combos that are twins on the inside are easy to work on. It is also easy to clean both sides of the lens of these models. Grab up as many as you can if you are into that sort of retro-technology. They are not the best for image quality or smoothness in operation, but they get the job done as long as VHS tapes are physically viable.

I just replace the entire capstan bearing.

Hi, I noticed from your video that the previous owner soldered a wire from the antenna to the battery terminal. And then there's a ground wire from the other side of the battery terminal. This was not original. Any idea's why? And do you know if there are wires connected from the back case to the main body? Thanks!

Factory reset, EASY

HiFiEngine has stopped any new registration, is there anywhere else you can get the schematics. I’m trying to get the schematics for my power field supercube reference but hitting wall after wall.

Excellent video, thanks for the unedited version.

Necesito esl diagrama esquemático de este radio, si me pudieran ayudar a bajarlo p como conseguirlo

i have problem with my pioneer vsa-1000..after on.disply ok..but no sound..i replace bad ic7812.7912.78m56a..but no power in to ic regulator.

Im a finish carpenter, lots of patients, but i migbt just smash it with my framing hammer.

Cassette in, unit blinking does nothing, remote or manually

To actually see the hard drive you have to go back to home and select hard drive there under "title". I just went thru everything you just did but pressed rec with video connected, stopped after a few seconds, selected home and title and the hdd and ok to select what I recorded. All is fine. Drive is formatted.

8 yrs later I'm back. No responses.

Greast Video my Denon CD Dual CD-R Burner I have had since 2005 was not letting me put the CD in the tray I would stop the tray by holding the tray so I could put the CD in now its opening and closing by its self I have the same issue with my Sony VCR that like to eject the tapes by looking at the videos including yours I would like to know where is the best place to buy new belts let me know your video helped out alot Thank You .👍👍

Hello i have tascam CDA 700 and When I plug in the turntable and turn it on, the CD player drawer opens by itself, closes again, opens again and stops. It is impossible to play a CD and every time I press the open close button it does the same thing to me. Do you have any idea where it may come from thank

Chido

Love this radio, It would be interesting see a video recap and the Q303 mod,

Looking good

Git it working after watching a video that talk about getting the gears in the home position.

After following this procedure, the tray opens half-way when I press the open button and sicks and will not close until powered off. Any idea what I did wrong?

So far' Nock On Wood" Mine is still working. Don't want to go through that. Nice job, thanks for sharing.

Hi I have a old,but nice Samsung model (PS50Q97HD) plasma Tv that I’ve been working on for a number of weeks and is proving tricky. I initially got the set working and was busy upgrading the cooling and efficiency bid the (X) and (Y) main boards by adding small fans to pull heat through the heatsinks. I then replaced the(X) and (Y)mains and when turned on a transistor violently (exploded) shot across my he room just missing my head😡, ok so a (dead short) somewhere on one of the boards. I sourced a working S/H (exactly the same) replacement PWR Supply board. Before fitting I re- flowed all the joints on the Transistors, NPN PNP, Voltage Regulators,Mosfetts. Etc. I then replaced all major capacitors on the PWR Supply with new ones. Plugging in with (Test Bulb) connected (bulb in series with load) the Tv goes into classic (boot up loop) When connected directly240v TV PWR Supply keeps taking the 3Amp mains plug fuse,when I’ve used 5Amp plug fuses blows them to. When plugged in directly to 240v there was a loud (Bang) rhe exactly same transistor blew as on the original board and also tripped off the(Socket circuit) RCD in the flat. So there is (Definitely) a issue and/or (Shorted) component on the PWR Supply board.it’s difficult to test outputs to various other boards from the PWR Supply whilst it’s hell bent on blowing fuses. Advice and guidance would be much appreciated Jason

I can verify, those Panasonic drives were very unreliable. We would have to waste our tech time filling out the paperwork to return the "core", just to have it returned to the parts shelf and fail again after installation. A fellow tech marked one of those core Panasonic drives just to see if it would be boomeranged back. It was. 👎

Bonjour, Merci beaucoup car j'ai pu réparer la porte de mon micro ondes Panasonic qui a 22 ans et fonctionne toujours graçe à vous.

Shango would have uttered the Flavor Country description of that unit.

Note about the rear fan: in a few of these Panasonic units the fan becomes active shortly after a DVD is inserted and playing or being recorded - it is not designed to start when the unit is first powered on and run constantly while idle - it is for the DVD drive only. This is true for DMR-EZ47V/DMR-EZ48V models.

I like your Current Test Board!

OMG good job🥰🥰

how does this compare to the Conrad Johnson Premier 11 A or Conrad Johnson Premier 140❓

That laser lens was yellow from tar before you cleaned it, and reflected blue after you had finished! People should realize that yellow tar is in their lungs to a greater degree than on the lens!

Gotta remove the customer label to see what mode the unit is in: VHS/DVD/Card
