Sony Trinitron TV 1990

I just got a digital cable box from the cable company and before this had the tv (sony trinitron model KV-27TS20, manufactured april 1990) thru vcr and for some reason years ago when i hooked it up, had to use channel 4, 3 wouldnt work.
this new cable box i MUST have channel 3.
at one time or another i must have scanned for channels so the tv would skip the channels that had nothing on them. and there was nothing on channel 3 so now it goes from channel 99, then up to 2 then up to 4, skipping 3.
ok im not stupid, need to get to the menu.
I lost my remote, havent seen it in 5 years.
any way to reset it? left unplugged all nite and didnt do anything. no buttons on the thing to do anything but adjust color and such.
i searched around and on some site found a dynatron #mr110 sony remote that would be able to bring up the menu as original, and its $25 plus shipping. regular universal remotes dont seem to have the scan channel feature, so i need this remote i guess, called sony miracle remote.
do i really need to buy a remote? ive torn my house up 3 times last nite.
just need to get to channel 3 on the tv and im sittin in fat city.
thanks
