It is a capacitor numbered C501 and it's 0.01uf 5.5v.
You have to remove the mechanical part to get to the board.

Re: Loss of station memory on Daewoo VCR

Most of the late VCRs (since the '90s) didn't use a backup battery, but instead had a special high value electrolytic capacitor which serves as a temporary voltage source to maintain program info. If by chance it has a battery backup, I'd guess it is a button cell, something like what is used in a wrist watch. You'd find it on the main circuit board- perhaps soldered in. If it has the capacitor, perhaps the cap. is bad. This also will likely reside on the main circuit board. This may be shaped like a button cell also, but will have a plastic wraparound label with the voltage and farad values on it- perhaps like 1 farad 3 volt or something similiar. If someone has a more accurate diagnosis...

Hi all, i have a problem with my vcr nv-sj500 it can't find all the channels ... it's shows only a few of them.. i'll tried to do search in the settings but still it is find the same channels but not all...

If you can find the factory reset do so and then retune. Some video's remember the previous stations and don't delete them, even if no longer there.

I bought a used Daewoo DVK47N VCR player which works fine but i can't get the menu to come up. It will record if I push the record button and it plays back just fine but I can't program it.

You say "used" it may be the person who sold it you gave you the wrong remote. I should look around on Google for the model number and the number on the remote, to see if the two match up. If you have the manual it will often list the remote number. If you don't, try the Daewoo website, sometimes they have free PDF's of manuals. You could also ask them if the remote matches your model.
Otherwise it could be a fault in the electronics section of the VCR.

I want to adjust the VCR operating frequency on model MX 728E. The VCR frequency clashes with that of a local TV station and it interferes with reception and you have ''ghost' images in the background

Depending on the age of the VCR it will have either a small screw on the back near the aerial socket, or the adjustment will be on a onscreen menu somewhere. It will be called the "RF OUTPUT".
They way to do them is for the screw type - turn it slightly - then with a video playing (something that you can tell what to look for) retune your TV. You might need to do this several times to get clear of stations.
With the menu type you just need to enter a RF number. This is often the best type as most VCR's give you the full RF range. Whereas the screw will only be a short range. Enter a RF frequency number which will be well away from broadcast stations. You can find which TV stations broadcast on the frequences in your area by looking it up in Google. Once entered, play a video and retune the TV to it.
Some VCR's allow the output to be switched off. You can use this option if you have the VCR connected via a scart lead. As you don't need to have the TV tuned in to the VCR.

How change RF channel in Sanyo VHR H772

Is there a small screw on the back near the aerial? If there is it's the RF adjuster. Turn it slightly. You will then need to retune the TV. It's best to have a video of something running so you know what to look for. If the VCR doesn't have a screw at the back, the RF adjustment will be on a menu somewhere.
You might need to retune both VCR till you get clear of any broadcast station. I must point out that if the TV has a scart socket you will get a much better picture from that. If it has only one and you have other things connected, get one of the scart switching boxes (Amazon). It will solve any connection problems.

Need to retune Sanyo VCR VHR-610.

On the Sanyo VHR-610 you start the TV auto tune by holding down both the CHANNEL ( +, - ) buttons on the VCR simultaneously for more than 2 seconds.
The TV stations in your area will be automatically preset in order starting from programme position number "01"

When all available stations have been preset, the function will stop and the TV station preset to programme position number "01" will be tuned on your TV screen.

In other words after holding down the two buttons, leave it alone for awhile (takes some time) till it ends back at 01.

How do I hook up a daewood vcr to a TV through a Direct TV

If you are trying to connect a VCR to your television and still have Directv, this is the way to do it. Disconnect your Directv receiver from your television, Then connect the VCR to the television either through coax or RCA cables. If using the coax cable connect the out to tv on the VCR to the television. If using RCA cables connect the RCA OUT to the television AV1 connection. Once that is done, connect tha Directv receiver to the VCR using either coax or RCA cables. the Directv receiver only has RCA outputs so, if using RCA cables connect to VCR in. Remember that in order to see the Directv the VCR needs to remain on and it must be on the channel line in. If using coax cable connect to the VCR where it says in from antenna. Remember that if using this method your VRC does not have th remain on to view Direct. If you're trying to record Directv, then your VCR need to be on the same channel as the Directv output channel either channel 3 or 4. If trying to record Directv using RCA connections the VCR needs to be on the AV settings. If you have any futher questions please feel free to call me at (361)510-0339
