Re: Sceptre x20g-NagaIII (x20wc-gamer) issues.

Came up with P/N T491A226J006AT for the original unit. Sounds right: http://www.mouser.com/Passive-Compon...=A226J&FS=True

Just not available. :s Looking for alternatives.

Thoughts?

Sometimes I love ebay.

Parts ordered. I'll let you know how it works out. :o

After a long vacation (sorta), I've installed the parts. Bam, working perfectly for the last two days! Thanks for your help all!

First step, there are two connectors on the lower right corner of the picture of the back of the power supply / inverter card. Note that some pins are labeled Gnd, 5V, 12V. With DMM measure the voltage from GND to 5V (should be 5 volts) and from Gnd to 12V (should be 12 volts). If either of those are missing, it's most likely a problem with the power supply, disconnect the logic card to be sure (turn off power before disconnecting it!!!).

I've got a problem with my screen going blank after a few seconds - backlight just shutting off, seems like. I went to take measurements but don't understand the bolded part here - you can't get power to the power supply card without the logic card being plugged in.

There are three bulging caps (of 8) on the power card so I suspect this is my problem, but the voltages are ~12.3, ~5.15, and ~5.15 (both before and after the [what I assume is the] backlight cuts out). If the caps were the problem, wouldn't these voltages not be correct? Or could the logic board be cutting the load when there's a voltage drop?

I should also note that there's a slight hissing that lasts for 1-3 seconds whenever I turn the monitor on - anyone know what this could be from? Nothing smells especially odd.

To any one else reading this thread for info, I got the same values as in post 3, though the regulator brands/model numbers are different.

(Apologies if it is in bad form to revive this thread with a tangential question ... is there no edit button for new members?)

You have to replace at the bulging caps first before going further, otherwise you will be chasing your tail. The hissing sound may becoming from bad solder connections at the end of the lamp.

I see some Samxon GF Series on the power board - a series known to go bad.
