Appreciate some help with this SC board, Originally started out with 10 blinks and I narrow it down to the SC board found a few bad fets order the set from China and replaced all the fets and diodes since they were under a buck each also replaces the two fet drivers IC 521 and IC 501 M81737FP.
Put every thing back together ,power it up now I got 6 blink, pulled the Sc out back and start checking each component and found one dead resistor and diode , I replaced the diode and the resistor with a standard 1/4 watt resistor closed to the same value .
Hook every thing up and try to start the tv up still got 6 blink , after further testing I found a set of small grey capacitor ,C 645, C646, C661 and C662 ( they are rated 630v 1000P) that are dead ,cannot get any reading ,no ohms or diode reading from them , but there is one cap that is similar to the dead one that I do get a reading out of C641, 630V 2200P. This cap reads like a diode ,reading in one direction , could those caps without a reading be dead?.
