Vizio V555-G1 stuck on wallpaper; now stuck on V logo

A few do, but they are the only ones who stand to lose money from shipping costs because they unknowingly or knowingly sold junk, hence the policy and why I don't worry about buying from ebay. It is a pain if you very rarely run into that situation because it does take a little time to get another replacement but the crooks are not getting away with anything and they soon realize it and give up if they have any sense at all.

I understand everything, but there are people who don’t even know what they are selling and whether it works or not; they found a TV on the street, dismantled it for parts and put it up for sale...

[nomoresonys]

Lots of people knock ebay but like I said the VAST majority of people are honest. And if you have a doubt about a seller that's what feedback is for, and their policy does favor the buyer but it almost has to, hence sellers should always pay for insurance, they are not a HUGE company for no reason, their policy works and I never sweat buying from ebay. They did make a big mistake by excluding sellers from paypal but that's not relevent for buyers.

There's quite frankly a whole lot of people here and everywhere, that jump to conclusions and are buying boards to replace boards that are not even bad, they'll buy one board when it's really another board that's bad, then they think they have two bad boards when both may be just fine or it's no board at all but the lousy panel or a backlight connection or some weird short in a wire. Then they think they bought a bad board but it's something else wrong, that's where testing comes in. It's really best these days to buy boards in sets, sj and a lot of others didn't start selling sets for no reason. It saves a lot of trouble with compatibility, specially when a lot of the buyers are just novices trying to fix their tv and don't have time or the inclination to dive deep into electronic repair.

Look how many people, even on this forum, buy boards, motherboards, power supplies, t-con boards, and when installed on their TV, the fault remains the same...
I'm not saying that everyone is a scammer, but there are also cases where you're lucky.
It’s just that there is no guarantee on used boards, today it works and tomorrow it works, and after three days you turn on the TV, but it doesn’t turn on, since this board has already served its purpose.

[nomoresonys]

This is because people buy a working board with a broken screen, and then resell their non-working board to someone else....

Was speaking to THIS, where you basically call everyone a crook, I've bought hundreds of boards from ebay and as far as I recall, only received one bad tcon, which was refunded on the spot, that's who's selling things on ebay U.S.

[nomoresonys]

Doesn't matter, if buyer says it was bad, they get a refund, PERIOD. A seller with any sense insures the board.

[lotas]

So, maybe you burned it during connection... and or damaged it during transportation and delivery, and the seller will prove that everything worked for him, there’s no way to prove it.

You evidently don't know how ebay works, if you are sold a bad board, you get ALL your money back, so the vast majority of seller are NOT selling bad boards on purpose. Plus most people are honest, at least where I come from.

Nice! Thanks for the help! I made an offer on one so we'll see how it goes. I'm a little nervous though because I've read about people replacing main boards in Vizios with this same problem and it didn't fix it... Somehow.

That one is a little cheaper but not much of a warranty: https://www.ebay.com/sch/i.html?_from=R40&_trksid=p2334524.m570.l1313&_nkw= 756TXICB02K040&_sacat=0&_odkw=+905TXJSA550005&_osa cat=0&_sop=15

[nomoresonys]

Yep, that's a match, all the serials that sj lists will work and both these bar code numbers 756TXICB02K040 or 905TXJSA550005, they are interchangeable.

[x_orange90_x]

It depends on the serial number as to which board you use. https://www.shopjimmy.com/search.php..._query=V555-G1

Mine is LTMWYILV which looks to be the most expensive and hardest to find 🙄 I did find the following that according to SJ is compatible:

Well looks bad, probably an eMMC issue, symptoms are there, maybe Diah is right on his theory, check ebay, they might be 25 to 40 bux for a mainboard, which isn't that bad for a 55. if you get one make sure you match up the digits on the white bar code sticker to insure a match.

It makes me so paranoid when there's SPECIFIC model boards but many models used for a single tv. In the case of this tv I've found there are two physically different boards, one having less ribbon connectors than the other.

So there's nothing that can be done without removing the eMMC and reprogramming? I don't have the hardware for this so I imagine a new board is my only hope in getting this tv working again.

[Diah]

its non HW issue, neither eMMC dead---- its just firmware issue chromecast os.. POINT

[lotas]

Test the little brown mlc caps around the mediatec chip, see if any are shorted, do the same for the eMMC.

I wrote about this.
