Re: VIZIO E320VL Powers on then shuts off within a few seconds

I had the exact same issue as been described by several post. I am in a unique position in that I had two of the exact type of units. I swapped power supply with the same results. I contacted VIZIO. I was not very happy with there customer service rep. She insisted my problem was with the power supply. After getting nowhere with her, I ordered the eeprom U18 from a site on ebay. Soldered it in, and everything came up working. I got a survey from VIZIO about my contact with their customer service. At least I got to vent....

Re: Chimei DAC-19M009 Power Supply problems

Hello, This is my first posting. I have read all the posts I can find on the DAC-19M009 Power Supply problems. I have two Viewsonic VG2230 monitors. The first one failed about two months ago and with the help on this thread I was able to get it up and running by replacing the caps and both of the mosfets. I order enough parts to repair the second one as I was sure it was not a matter of if, but when was the second one going to fail. Sure enough yesterday was when..
After replacing all the caps and the mosfets I have the 2 second...
