Hello guys, this is a short quick write up because I don't have much time.
I´ve found a new converter for the ThinkPad T420/T430 on eBay a while ago. (He also sells converters for the ThinkPad T420S/T430S)
I´ve purchased it straight away and installed it with the B140HAN01.2 panel on my ThinkPad T420.
Before I purchased the converter, I contacted the seller and asked him for the flicking issues.
He replied with ¨We do not find the flickering problems, if the item causes your screen flickers, you can return it back to us.¨
I´ve got the converter and panel installed now for a good week, and I must say, I do not found any issues with flickering. (Which was the case with our converters from Javie-Jie, no offence to Javie-Jie)
But I think the flickering does not occur because of the separation and the mounting of the converter board behind the panel. (Anyone with a better electronics background please correct me)
Where as the converter board from Javie-Jie was on the connector which connects to the motherboard. (Electromagnetic interference)
Look at the included link to my Nextcloud where I´ve put some pictures of the installing of the converter board with panel.
I´ve already asked for the production and stock amount for the converter and the seller replied with:
¨This item is in production, but the yield is not high, and the speed of testing is not fast,
we will test one by one to make sure it is OK, so sometime it will not be in stock.¨
The seller of the ¨genuine¨ panels replied with: (By the seller on Aliexpress you must write with the order "B140HAN01.2" Otherwise I think he would send you an LG or some other bad compatible panel)
¨We have this in cargo¨
Research story of the panel was actually funny, because if you lookup part number ¨04x0436¨ on
https://support.lenovo.com/be/en/partslookup, you get the same pictures as the seller on Aliexpress.
I´ve got some more research information and pictures, but these are unsorted files, so PM me if you are really interested in this.
