Matsui TV - 20TN (D4N Series); No Sound or OSD
 

I have this problem, suddenly. Following the instructions at
http://www.eserviceinfo.com/repair_t...atsui_029.html seems to have no
effect, although I am unsure EXACTLY what the procedure given there actually
is, in detail. For instance, it is not clear whether the SC on PL701 is
supposed to be applied when the power is on and the set in standby (because
you cannot switch the set on with the H/S if the set is off), and what does
Chan down 3 times mean, and what is the TV button (TV/AV?) ? Also, the
word Tatung appears nowhere in or on the set.

Thanks in advance.
