If it's like most Matsui VCR's I've stumbled across, possibly it's just the VCR's modulator is switched off. If so..
Either use a scart lead between VCR & TV and select the corresponding AV input on the TV or for RF connection, check that the VCR's modulator is turned on and it's output set to a UHF channel no. (CH) as follows..
Switch the VCR to standby using button on front of unit. Then press and hold the standby button down for 5 secs until RF -- is displayed and use channel up/down keys to set an RF output CH between 21 & 69. You can then select a spare channel position on the TV and tune the TV to that corresponding modulator CH and/or test pattern.
Then select auto tune on the VCR.
