cncxa na mga guys na busy kasi ako sa pagrerepair ng walang kabuluhan ......
TIP's for sharp T.V
Problem: no power, shorted H out..
Conclusion: remove H out then replace the open fuse after that observe the T.V if there's a power on the primary and secondary if there is a voltage,now lets take a voltage reading at the
B+ without H out if there is a voltage range up to 90 volt + at the B+ block diagram, observe or
try to test all pin of FBT,if there's no voltage it should be no oscillation at the B+... Now lets check the parts like diode,resistor and capacitor.. When they are ok in the tester now lets look the loss contact on the board...When they finish to resolder all the loss contact and lets get back into a voltage reading again at the B+ if there's no voltage pass through the B+ now let's find the resistor, and the resistor is should be a 1.2 ohms replace it...!!! And all will be ok...
