Bush Btv18

[Edmond]

Hi Guys!

I need a schematic diagram for BUSH BTV18, and the way to enter in the service menu.
The TV was made in England. The tuner is set to UHF and the sound to 6MHz.
I’d like to enable the VHF I-II-II, and set the sound to 5,5MHz and 6,5 MHz, if is possible.

Thanks for help.
Edmond

I found the BTV-17, but is not similar to BTV-18. The main processor and the IF IC are different. I found the BTV-18 too, and I changed the sound system in service menu.
