Re: Memorex MLT3221 - No Power
more test:
operation the p/s out of the tv,connect 220AC
at con. 3, between pin stb to 5vsb solder 1k resistor-got 5v,12v,22v at output
at con.4-5V with 1k resistor connect to pin BK-ON
results;got high voltage for 1or2sec,the red led blinking,12v supply for 2 sec to ic8 pin 13,15.at con 3 no change 5v,12v,22v are on
be continue
