EBay Defective Item (Mainboard)

63 14 December 18, 2017 at 09:07 AM
Hello,

I recently purchased a defective mainboard for my television on Ebay and was wondering if this is common on the website....

It says it was pulled from a crack screen television, however, this TV was sold more than five years ago... Makes me wonder if the sellers actually test/know if they're mainboards actually do work or not.

If anyone has any background on this, please feel free to respond....

Thanks.

of course, they prob never even tested it....... There is a reason why it's called flea bay... Tell them to refund you full price and if they want it back, remind them that it's the sellers responsibility as of 1 year ago to pay for the return shipping...

Have you ever purchased a mainboard on ebay?

All the sellers say the same thing. (All from cracked screen, yet mainboard functioning properly and tested).

Kind of wonder if they just copy and paste each other and dont really test the mainboard, just scrap tvs

NO, but i can assure you most of them don't even know how to test a main board.... Does this place have a lot of reviews? good ones? if they do, It could be that they just missed this board.. and are you 100 % sure it's the board on the tv that is bad? do a you tube search and you can check the board very easily with a voltage meter

Pretty sure.

Initially, I thought (after installing the new mainboard from the EBay seller) that it was my power supply or both, however, I changed my power supply and it still didn't work. Than, I changed my mainboard again to a different one I have (3 mainboards + 2 power supplies) and the television works (2 defective mainboards , 1 functioning mainboard, 2 functioning power supply). .

(I have 2 tvs).....

I had the solid red light power, but not actually turning on problem. After installing the ebay mainboard, the redlight was still solid and not turning on.

They had good reviews, but it was only like 8-9 reviews in total. Actually, I looked again, the weird thing is in their feedback, the items are all private and the buyer's user id as well.

that is a bit sketchy... also, if it's working with the other main board then that is the issue... Contact them, good luck!

to be the devils advocate, how do you know your issue is solved with a mb and it's not some other issue.

Because I swap my defective mainboard with a new one and it worked....

I also swapped out my power supply and used the ebay + my old defective one and neither worked.

Well you said you purchased a defective motherboard did you think it was going to magically fix itself?

"I recently purchased a defective mainboard for my television on Ebay and was wondering if this is common on the website"....

Not quite sure why you did not purchase a working one?

Long story short.

Ebay basically said they would refund me the full price and I wouldn't have to pay both the shipping fees to return the board and to restock it.

Hopefully, the seller doesn't try to swap out the mainboard and lie to Ebay.

How could they test it without another identical TV?

Before I buy something from eBay, I contact the seller and ask specifics, and if all I get are generic answers, I avoid. For something like a circuit board I'd ask for not only its model number but also the revision number and the brands of MOSFETs and capacitors on it and how the board was tested. If they say they used another TV, then ask for a photo of the diagnostic mode screen, which can sometimes tell you the model and revision number and even what firmware is in it or how many hours it was in use.

Your definitely right.

However, these dudes rarely answer questions on ebay. Anyways, I bought a new "used" one and hopefully it works.

SO, I used a different mainboard (however, was accepted on the list Shopjimmy has) for my 50 inch samsung and the original mainboard for the 50inch samsung on my 55 samsung that was defective.

The return still is in process, however, Ebay said I would get my full total back 100 %.
The ebay one that works cost 15 usd (+ free Shipping), while the defective one was around 60usd.....

Interesting experience.....
