Konka T2566E-type color TV boot whiteboard input AV signal plans sound normal
Local small-signal processing circuit used TB1240 Manifold, CPU for CKP1006S (MP87CK38NF).
AV to normal, so the first measurement of the discharge part of the voltage value TBl240 found ? pin AGc terminal voltage is 0V,
check the external components to normal, for a TBl240 not solve the problem, then think of the bus changes will lead to closure of AGC,
just enter the bus.
Method: User remote control Y216 restructuring. The remote control panel open the second half of patch,
in the bottom row of keys to find FAC, using conductive adhesive press the button, upper right corner of the screen shows PASS WORD,
