Look Sparky model number is not important because the name of TV is VOX J2133 and this name is created from importer of this unit, but on the chassis is printed mark KP21TK312Q . This is KONKA designation for chassis.
Procesor is TDA11020H (big SMD chip). There are two version from this chassis :
1.one version where the main power switch is build on chassis, IC receiver and all knobs (P+,P-,V+,V-,TV/AV
and MENU)
2.one version without main power switch and all knobs are on separate board
This chassis is very similar with TK-A(Q) chassis from KONKA but in this chassis is processor TDA1200H (big
SMD chip). The both processors are very similar but there are differences. Pinout of processors are not same.
From TK-A(Q) chassis I have diagram.
Thats the reason why I ask for diagram for KP21TK312Q chassis
