tatlo dapat ang supply ng tuner sir,yung 12v lumilipat yan depende sa channel na select mo VLF,VHF at UHF.trace mo yung pcb foil kung saan papunta at yun ang i check mo yung mga parts nito.

tama repair first the supply..

baka naman loscon...lang sis kasi ang 5v nian ay galing sa main reg...from chopper...kung nawaala 5v check mo nmn pin 8 ng eeprom at b+ ng reciver ng remote con... kasi lahat yun 5v iisa lang ang kinukunan ng supply nun kung di ako nagklakamali...

sa 12v naman baka nga sa fbt galing...baka may loscon ka sa board
