My first post, hoping this experience will help someone.
On Christmas morning my Vizio e701-a3 which I've owned for ~2 years died (thanks Santa). I bought a used set that was manufactured in Oct of 2015 if I recall correctly.
Symptoms:
- Random, infrequent shutdowns (few times a year) since ownership
- No popping noise or warning whatsoever, it simply shuts off
- Would normally turn back on after several tries
- Completely unresponsive. No picture, sound, backlight or LED indicator
Troubleshooting:
- Suspected power board. Checked mains connection on board. PASS
- Checked main fuse for continuity. PASS
- Checked output terminals connecting to mainboard for voltage. PASS
- Power board OK. Suspect mainboard.
- Ordered mainboard from ebay for ~$100 CAD shipped and installed. FIXED!
I was really hoping it would be something simple (and cheap) like a blown fuse or cap. But, as you can see, what appeared to be a power supply issue turned out to be a mainboard problem.
My electronics knowledge is limited so I didn't troubleshoot the components on the mainboard. I decided if replacing it didn't work it was time for an upgrade. Guess I'll be holding off a while longer for 4K
