1 Answer

E322VL has power but will not turn on

Amber vizio light is on but never turns white and I can't turn the tv on. I tried the remote and the power button. I have 5.4VDC at the pins that go to the main board. Any ideas on how to narrow down the bad part?

Its usually a capacitor on the power in circuit board..Little black canasters..you will notice the top of the bad one will be arched or swollen..sometime gell will be oozing from it also. its usually very noticeable when its swollen when compared to the others around it..

    I looked at the capacitors and they all look perfect. Is it possible to test a capacitor without removing them? I should also mention that I replaced the power board and the problem is the same.

SOURCE: My vizio e320vl turns on shows vizio screen and turns off. How can I reset it? I have tried unplugging and holding the power button down for thirty seconds no results

Set could be shutting down as no signal (usually 30 seconds or so) or it may have a power supply problem.

general info:

I see so many here with no sound/nopicture issues:

ISSUES:

1. IF sound main fuse/s are good.
2. If no power or standby check main fuse, standby power supply and any signsof damage you can see---burnt parts etc.
3. almost all these sets the troubleshooting involves checking voltages on the main power board to narrow down theproblem.
4. Be safe and if you do not know what you are doing don't open the set.

Answers to issues:

1. RE:fuses---if a blown fuse is found get a good replacement(not the genericones like Radio Shack). Many fuses are special even aside from amperage--Don'tput a higher rated amperage fuse in the set for any reason.

2. RE: power supply in set: if total dead aside from main fuse the set uses astandby power supply that runs 7/24 and a main supply (some are combined andsome not.

Here aside from checking fuses you want to examine all the filter caps on thepower/standby to see if any are puffed up or buldged up in some fashion--Iattach a photo of a good one---top should be silver metal and PERFECTLY flatand have no brown material coming out on top or bottom.

What happens in the standby area is they use caps with too low a voltage rating(saves money) which causes them to fail in a year or two---the standby runs7/24 and the heat dries out the caps and they fail.

3. Trouble shooting consists of the above and then at some point you have to buyand try a board to see if it fixes it or not.

4. Safety first--no TV set is worth getting injured or even killed over.If set is opened at least look for puffed up and bad caps like in thisphoto.

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.
