Question about Panasonic PV-DV910 Mini DV Digital Camcorder

1 Answer

Need to replace power/mode switch

Panasonic parts offers a "mode" switch part number VSR0230. Is this the grey lever that switches between VCR mode, camera mode and off?

If I buy the part, how do I replace it on the camera?

Panasonic PV-7400 VHS VCR seems to be stuck in Memory Rewind Off mode. I power on, it attempts to rewind (though there is no tape in there now) for about 20 seconds, then powers off. I've pulled

Most of these problems are caused by a faulty mode switch. If the mode switch has gone off of it's true position, then the electronics might well think it's in rewind mode even in the off position. Sometimes it's just the switch that is faulty, but sometimes damage to the mechanism has thrown off the switch.

I insert the tape and it stops and the power shuts off. If i turn the power on, it ejects the tape

This sounds like a problem caused by the Mode Switch. These in VCR's can cause all sorts of odd things. The switch can become faulty, or just get dirt in it. The switch tells the electronics of the VCR which position the mechanical parts are in. If the electronics get conflicting information, then it will power down the VCR. Another cause of a good mode switch to give wrong info, is damage to the mechanism. This throws out the timing.
A spray of Servisol Video 40 on the switch will restore a dirty one. The other causes are more tricky. Since the whole thing will need to be set up again in position. This will most likely require the service manual as most VCR's are never set up in the eject mode! After any faulty parts are replaced of course!!!

VHS cassette accepts and ejects with kir..r...r sound. I have removed the power cord (Power OFF) and cassette was inserted halfway and then plugged the power cord (Power ON). At this time the VCR ejects...

First of I think you have a K-Deck mechanism. If you do a Google search for "Panasonic K-Deck" you should find the free information. If you can't you will need to E-Mail me.
This sounds like a a timing problem, perhaps caused by some damage to the Cassette Holder. The mode switch could be part of the problem too. They are quite tricky to set up to get the timing right, I do know the Cassette has to be inside the machine to set it up. The good news is that parts are easy to get hold of, so if any thing is damaged it can be replaced. Curry's partmaster is a good place for parts.

Panasonic DMR-es40V F03 error code - VHS not working

Mechanical fault, usually caused by oxidisation of the mode switch - creating increased resistance between its wiper and its internal contacts. Try cleaning the mode switch (under the VCR mechanism on the main board) using a commercially available electronic cleaner (after first unplugging unit from power point, and carefully removing top and front covers), rotating the switch wiper gently in each direction, let it sit for a few minutes, refit the mechanism, ensuring all is reconnected to the board, plug unit into power, test.

The other option if the cleaning doesn't work, is to order and replace the mode switch with a new one - these are not expensive parts, and should be available from Panasonic directly. Make sure you quote the model number of your unit to the spares supplier before obtaining any replacement parts, including the mode switch as required.

BUT: try the simplest and cheapest option (cleaning the mode switch) first. See how you go.

Panasonic model pv-4351 insert tape, press play, vcr shuts off

Any number of problems can cause this. One of the biggest culprits is the mode switch. These tell the electronics of the VCR what position the VCR is in. However if part of the mechanism fails (could be anything) then a false position will happen and the Electronics shut the VCR down when this happens. Nevertheless the mode switch can be the cause of this itself, by having dirt in it or being worn out. Sometimes a spray of Servisol Video 40 on the switch will clean it, but it won't do anything about a worn switch or one that is out of position caused by damage to the mechanism elsewhere. So check for damage, then spray!

This could be caused by one of a number of things, but it could be down to the carriage (the thing the cassette fits into being damaged. Another likely cause is the mode switch. Again this could be caused by damage in the mechanism, throwing out the timing. You see the mode switch tells the electronics what position the mechanism is in. Any damage can throw out the timing. But mode switches themselves can go faulty. Sometimes dirt gets in them, which can be cleaned out by Servisol Video 40. Restoring operation. But damage will throw the mode switch out so re-aliment needs to be done. I think your deck might use the K-Deck mechanism. If it does you can find information on it, plus how to set up the mode switch correctly by searching Google for "Panasonic K-Deck".
Mode switches for K-Decks can be found on Curry's Partmaster site if you need a new one.

VCR's have a thing called a mode switch. This tells the electronics of the machine want position the mechanical section is in. If it gets wrong signals then the VCR electronics power the machine down. These wrong signals are often caused by damage to any part of the VCR mechanical section. Perhaps in this case something to do with the carriage unit. But the switch itself can go wrong. A visual inspection inside might reveal damage to some part of the VCR.

Panasonic VCR 7350 displays error messages and cant insert tape

There is either some damage to the mechanism or the mode switch is faulty. If you know what to look for taking the top cover off might show what part of the mechanism is damaged.
If it is the mode switch then it will need to be replaced. This can't be done without the service manual as the vcr needs to be set up. And they are never set up in the eject position.
