Re: Dell E172fpb

OK, I am a nexperienced electronics and computer technician. A customer of mine )who is very important to my business) gave me an E172FPb to repair. The symptom was the very common on for about 2 seconds, then blank screen with the green light staying on. Power supply voltages were good, caps all looked perfect, there was a little discoloring around the output transistors and only one of the transformers. Cleaned up all the solder connections around the inverter section, replaced the driver and output transistors, and the problem persisted. After much deliberation...
