Re: Help wanted with B/W TV Mod
Hi Studio263,
Thanks, I wasn't expecting a reply quite that fast.
The Base of Q801 is quite convenient to get at, and disconnect from R262, so I will hopefully
have time tonight to experiment on that.
Thanks for reminding me about the Bias, I'd not thought about that, but it should be fairly straightforward to set up a temporary adjustable Bias for testing to get the final required level.
The Audio side of things I don't have a problem with, that's fairly simple.
Regarding the UHF Modulator, that would for sure be a simpler solution, but I want to avoid up converting
the Video Signal just to have it down converted again with the associated loss of quality.
I have also had trouble with interference between Modulators and some Freeview Boxes in the past as well.
Most importantly for me though, is if I can successfully convert this Set, I will move on and try the same type of mod on one of my other portable Sets where there really is no room for a Modulator inside.
I bought this particular Sharp 5T especially for this experiment to gain some knowledge as it has plenty of room inside and all the Boards are quite accessible.
