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.

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...

TV will not change or show channels


You don't say whether you have had it working at that location before. When you move a TV between houses, it is necessary to retune your channels. Would recommend returning to first time installation.
If you haven't moved it recently there are other reasons why this might happen. 1) There is damage to your aerial caused by weather, 2) A power surge or loss of power to the memory battery on your video board has wiped the frequency information from the memory [the memory battery is like a watch battery that keeps a small amount of power going through the system to it can keep your settings when unplugged], 3) The internal tuner board for your TV has packed in.
If '1' is the case, obviously you need your aerial fixed; if '2' is the case you need to retune again [you'll know if the battery is dead if you have to retune every time you turn on the TV]; if '3' is the case you either need a replacement AV board or someone to solder a replacement tuner board to it.

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.

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.

Cheers
