SHARP 27E-S50 Vertical Bad
I am working on this TV set trying to search down the exact problem.
So far I have not found any bad resistors or caps to IC501 (LA7838) or anywhere else on the PCB. My question is, Pin 12, is an output. I read the voltage should be 13.5 - 14V but I am only getting .11V . Is this an indication the IC is bad or that it is not recieving an input voltage / signal? and should the other pins (such as 5) have voltage output? Voltages readings were - Pin 1 is 10.8V, Pin 8 is 29.2V and pin 13 is 26.4V. Any help is appreciated. Thanks! |
