First of all thank you for posting your question here at Fixya.
I'm assuming here that you're TV is a Vizio L32 HDTV.
My initial advice is to ensure that the AC source
(outlet) is live
. Please plug the unit to a known working outlet, if you are using a surge protector, directly plug the power cord of the TV to the outlet to confirm that the AC source is not the issue here.
If you've confirmed that the AC source is not the problem, then the fault is inside
the TV and most likely the power supply
. Most of the TV with a dead set symptoms that I've encountered is a power supply issue but of course needs to be confirm.
If your unit is not under warranty period
(if so, avail it because the manufacturer will fix it for free, opening the rear cover will void the warranty), open the back cover, check the internal fuse
of the power supply board, this is near where the AC power cord's directly connected. Check its continuity
using the multimeter/ohmmeter
, if you found it open, replaced it with a new same current rating
that is printed on its body itself. Sometimes internal fuse fail due to voltage surge/flactuation
, etc, replacing with new one resolve the issue, however if the fuse blow again
, this is an indication of more serious problem on the power supply board, it needs to replaced the entire board.
If the fuse is intact, you have to measure the output voltage of it through connector J1
). You should be getting 5 Volts
. If there's no voltage at these pin, you're power supply board is dead, replaced the entire board. If the 5 volts is present, replaced the main board.
