Since I started this hobby with thanks to all the people on here helping us all out, I have found to be having issues with different used parts dealers. Wondering if anyone else have been having trouble. I have bought many boards off Ebay and crossing my fingers and knocking on wood, I have yet to receive a bad board. I have used Payless Components a few times now and twice I have received bad boards from them. Shopjimmy has been good but their shipping charges are insane. I live in Winnipeg about 7 hours drive away from them and I pay $50 shipping. I understand it crosses the border but Payless charges $10. I have dealt with Useful tv parts and no issues but their stock is limited. Has anyone had issues or recommend other suppliers?

Re: Buying used parts
Ive gotten most of mine from recycled tvs, but they take up a lot of space. ShopJimmy is my favorite as I have a almost 100% certainty that they are good. You might try getting them from ShopJimmy off ebay. They charge a bit more for the boards but shipping is much more reasonable.Liberating magic smoke one part at a time -
Re: Buying used parts
I've ordered three items from Shopjimmy. Two were dead on arrival. The first time, they sent a PSU that arrived with a blown fuse in it. I replaced the fuse and it blew again immediately. If it had been tested as they claim, it would have been pretty easy to tell it was not working. The second time, I ordered a control box for a 32" Polaroid. It took two replacements to get one that actually worked. The first one wouldn't allow the input to be changed, the second one displayed vertical lines, the third one fixed the issue.
There is no certainty that ShopJimmy's boards are good and they obviously don't test all of them.Comment

Re: Buying used parts
I ordered a Sony main board from shopjimmy, they said the board was new, tested. So I installed on my TV (My TV had color distoration), it didn't powered on, when I unplug the cable to the panel, it powered on but of course no picture.
I called Shopjimmy but they answered only one guy could determine the main board failed, without that guy determination they were not willing to refund. Emailed them a couple of times but no reply.
Finally got approve to return, they refund the board, but I had to pay two shippings (return and the fee they shipped to me).
since then I never buy parts from Shopjimmy.Comment

Re: Buying used parts
With the amount they charge for shipping, I am very reluctant to use Shopjimmy. Payless may have sent me a bad mainboard but gave me an RMA immediately. Cheap shipping and very honest. I haven't used retechtv yet. I will if they have a board I need.Comment

Re: Buying used parts
100% success with Payless so far with about 10 items purchased. You must have been unlucky but as you say SJ shipping is a killer, Payless has a flat rate but I suspect he's losing on some. I had a SN board sent to Australia and $15 USD, sticker on the box was around $30.
He use to combine postage but last transaction for whatever reason he never did, even after he said he would?
So with 3 boards I was charged $15 / board. 2 travelled together still charged $30.
Compared to SJ I'm still miles in front though, just not as sweet a deal as it was when I first purchased.
I got a 20% off discount for my next purchase from Payless.
SJ needs greater flexibility on their International postage. There are cheaper options and I'd like to get a repair kit but I'm not shelling out $50 for an envelope with some semiconductors that weigh almost nothing.Comment

Make that 3 bad Westinghouse mainboards now! I am so over this panel I might take it out for some target practice!Comment

Re: Buying used parts
I emailed them after and I questioned them on the shipping charges and got the blah blah blah email back. I wasn't impressed at all. I'll use them to ship to a warehouse I use in Pembina, ND but not to Canada. I do try to use Payless as much as I can.Comment

Re: Buying used parts
So much for Useful TV Parts. Only ordered from them once and they sent me a faulty buffer board. The easiest board to test with a meter and they didn't do it. Not impressed.Comment

Re: Buying used parts
Adding to my last post. I emailed them and they are letting me return the part but they told me they tested the board. Basically calling me a liar. When I have 0 ohms from the white connector to one of the ribbon connectors, that is a blown buffer chip.Comment

Re: Buying used parts
Can be hit and miss. There are quite a few recylclers now that probably do the right thing and if it's DOA sort the issue out.
I always look at how many sales they've made, feedback score which ideally should be above 99%, terms of sale, returns etc, always look for the negative and neutral scores and read them.
Quite often someone will say the bit was bad and have a followup saying full refund or replacement sent etc. Looking for their after sales service.
If the seller has multiple lots (eg 10 or more) of the same boards available then good chance they came from damaged in transit TVs sold in a lot.
Most do the right thing, but take the board tested remarks with a grain of salt as majority are not.
Worst case I had when I went outside Ebay to china for TCON boards. PAYPAL saved me though.
Always use PAYPAL. lodged 2 disputes for DOA sustain boards and got refunds on both.Comment

Re: Buying used parts
Wow, I have just called them, last week and they haven't answered and there site it was still up.
I have got a T-con board from them and I'm not sure if it's good or not. I wanted to talk to them, about it.Comment

The problem is, that it shows the same voltages at the Gamma chip as before.Comment

The TV is a Samsung UN65JU67ODFXZA Version TD01. I replaced the power source board and the TV is now working, but I decided to try and troubleshoot the old board to fix at the component level. Trying to get a schematic and a parts list has proven to be an issue. Trying on my own, I can't tell you how many times my Norton security has flagged sites as "malicious". I ordered a service manual from ServiceManuals.net, paid $16.99 and got 66 pages of everything BUT schematics and component parts list! Can anyone steer me in the right direction? Some of the surface mounted component parts... -
Opinion time - anyone ever fix one of these? I just fluxed and reflowed the BGA along with some thermal epoxy on the heatsink for the logic/motherboard and the issue is still the same (refer to video attached). Anyone think this is worth the gamble buying the complete board kit from SJ? $125 gets me a PSU, Tcon and Main/Logic. "Mouse" control works on screen until the crash. Would you gamble?

Hey, I find it very absurd that the SVOD4 costs so much and has zero documentation. I had no other choice than to buy it to unlock ECs, if there was any documentation or firmware avalible I could've made it or something simmilar. Anyways here are some of the most important parts:
STM32H723VGT6 MCU - It's a microcontroller by STMicroelectronics and its the whole brain of the SVOD4. It has flash memory for the firmware which can be updated by the SVOD4 program. Its also powered by the AMS117 which converts 5v into 3.3V. 7€ on AliExpress.

I recently found myself the proud owner of a later-model Samsung plasma (the PN59D7000 for those keeping score at home) whose panel was, unfortunately, damaged in transport. I'm now preparing to part it out, but am curious as to whether or not any damage would have come to any of the components by attempting to power it up with the panel being broken. I read in one Avsforum thread (for whatever that's worth 😂) that the "scan driver boards" (by which I assume he means buffer boards) could be impacted by doing so. Is that actually the case? If so, since I don't intend on selling bad... -
Hi,
I have an Asus Rog Strix B360-I Gaming with missing parts. I know there is a resistor missing for sure, but nearby it seems there might have been also a transistor or mosfet. Below the picture of the area on the board with the missing parts. The interesting area is inside the rectangle.
I'd appeciate if somebody could make a detailled picture of this area from a working board and post it here. Getting the parts values would also be helpful. The revision of the board is 1.02 .
Thanks in advance...
