Help With My Vhs Player Please

[Tubbycoates]

Hi all, My VHS player packed up, and since I've a load of tapes,
I was given another one, no remote, but apparently nearly new.
I plugged into my telly and it worked fine, picture clear as a bell.
The following day I tried another tape, and this time I got just a blue
screen, but every time I played 'play' it went to the EXT output (as
expected), no sound, nothing. I tried it on my old telly, and it worked!
So I put it back on my usual telly, and again it worked with a variety of
tapes. The following day, nothing except a blank screen. I tried on the
old telly agin and the same thing happened as before. Following day, same
thing happened. I tried it on the old telly and this time, although it goes
to the channel that the player is tuned to, now it says 'no signal' I can't
get it to work now on either telly. I've tried switching on and off,
changing the SCART lead, everrything.
Does anyone know what I'm doing wrong?
Thanks all in advance.

An idea to try on my old telly, only goes to blue screen (ext screen) when a tape is playing on my new telly.
