Vizio service manuals are mostly useless and have no schematics usually, or very limited ones.

Re: vizio tv e420vo No audio

Re: vizio tv e420vo No audio

How many of these do you repair?

Re: vizio tv e420vo No audio

this type of board have a lot of problem with frezze logo, or not power on, i came to find out that the problem is in a small eeprom that is close to the center of the board, After you replaced that eeprom the board will start working normaly but some will have the audio problem. Don't know if the problem is related. don't think so, but i don't now much about this thing, just learning.

Perhaps the eeproms do not have the correct firmware?

Did you change the eeprom on this set?

Re: vizio tv e420vo No audio

yes. But the eemproms came from another board that turn on and off. Din't have problem with audio.

I have decided not to look at any more of your posts.
I know you are learning but its just too difficult.
You need to do more reading up on all the posts relating
to Vizio tvs if that is what you are working on.
I can only think you have started out on them as they are cheap - unfortunately they are cheap because they are often impossible to fix.
You need to stop providing some information but not all the information regarding what the boards are, where they are from and what you or someone else may have done to them.
As it is we have to drag every detail out of you and spend time looking for things that are just a waste of time.

Final straw is I have been looking all the time for info relating to a Vizio E420vo. I became concerned when you said you were just swapping eeproms between boards and I now find that the board in your picture in probably not from an e420vo but from an E371VL.

The power supply is also probably from an E371VL or E370VL.

It has been rather frustrating. I would highly suggest that anyone beginning to learn should first attempt to understand basic electronics theory (there are many resources on the internet) and try to learn and understand as much as possible before asking questions. I feel like it has been a wild goose chase and frankly I'm completely lost now. All you need to do is trace through a signal on the board but it's taken us over 4 pages.

Re: vizio tv e420vo No audio

Sorry for inconvinience. The board in the tv is from a e371vl but is the same board use in the e420v0. I check others comment on vizio but could't find anything that will help me.

It reminds me of this thread:

Re: vizio tv e420vo No audio

I never saw that post you send me budm, sorry i was mad with myself because no matter what i try i could not make it to work and i see you guys helping me but i dont know for how much time on it, so i desided to quit on that tv and buy a new board before you quit on me. when i'm working in a tv i am willing to go as far as you guys don't quit on me. Now everybody is mad at me. I'm just an old man trying to learn what i sure it leaned went i was young. You tell me the rules i follow them. One more thin the reason i did not mention about the board is because idid not think it was important. i have a good board from one of my tv wish is a 371 and i put it on this tv that is a 042 and it worked perfect so i din't think it was important.

Bye.

Re: vizio tv e420vo No audio

"before you quit on me." I DID NOT QUIT on you!
You gave up after over 180 posts.
"i was cheking the reading in this tv and now the tv turn off every 5 second. It is time to said like an familiar boxer said NO MAS!! You guys are champions. I'LL BE BACK!"
I will no longer answer any more questions.

Re: vizio tv e420vo No audio

I think I'm going to stop answering questions from people who are in it purely for monetary gain and give up on anything which is slightly difficult. I do TV repair as a hobby -- making money is just a nice bonus. Don't blame you for being frustrated budm. It frustrates me greatly.
