Have TV Questions? Ask a TV Technician
Hello, Sorry you're having problems. Does the set still have sound please?
Additionally, is that power light continuously flashing, or did it eventually change to Yellow and stay Yellow?
Thank you for the reply. Does that light start flashing as soon as the TV is plugged in, or only after you press power?
Okay, this generally indicates a faulty Mainboard in the TV, however in some cases the SMPS (Power Supply Board) would be the root cause. I am going to give you a reboot to try - which is the ONLY thing on a user level you can do and beyond that the set does require component level testing and replacement to fix the issue (which is on average a $250 repair on this set - and typically NOT cost effective on a 5 year old Vizio).
However it's worth it to try a hard reset, as sometimes the processor in the TV can simply have locked up.
The first thing you would try, is disconnect the set from power, then press and hold the power button on the TV itself (not the remote), for 10 seconds and release. Then plug the set back in, and also check that the power cord is connected tight at the TV as well. Press power once, and see if the set powers up normally. Try this procedure up to 2 times, and please let me know what happens.
Unfortunately that is all you can try on a user level, and this indicates the set has a fault either in the mainboard or the power supply board. There are no quick fixes for this and the set requires component level testing and replacement to fix it. The average cost for this repair on this set is in the $250 range, and given the availability of parts (parts are no longer made after around the 5 year mark), AND can be replaced with a brand new 39" LED for the same cost- this is not a cost effective repair.
I'm sorry for the bad news here and wish there were a quick fix.
