content: Hello,I need help on the field of knowledge and finding the wright stuff.I got a Samsung tv panel out of a philips 46PFL8008/K12 tv. The panel is from Samsung, type LTA460HQ23.https://www.panelook.com/LTA460HQ23_Samsung_46_LCM_parameter_24902.htmlThe mainboard is broken, a known failure of the mainprocessor going lose, due through the heat. I can't reball it myself and thats a short term sollution.So i want to use the panel with a universal lcd adapter to connect it to my raspberry, but i can't get the datasheet and can't find a suitable lcd board with cable for it.So my questions are:What is the differance between LVDS and V-By-one?Is it possible to connect the 51pin v-by-one to a 30pin LVDS board?Are there sites with more information about this (all the time aliexpres etc. come in to my search results and no forums of so?How are all the boards related to each other (there's av23, v56, v59, 4UHD controllerboard, MS6190, etc.)?Whats LCD board is suitable for this panel?Whats more to take in to consideration?A lot of questions, but hoping somebody could help me!Thanks in advance

content: Thanks for the quick reaction.How come that there is so less info on v-by-one and LVDS. And then i mean pinouts, etc.But also how they work etc.

content: Quote from: wraper on July 31, 2020, 06:09:52 pmThats one of the problems which i encounter, you can never check if it wil function with a panel because you can't find technical information or firmware for it.True on the economic value, but at the moment i got the panel and it's nice and thin, instead of bulky. I want to use it to make a magic mirror with it. So i don't need fancy 3d functions etc. For the mirror i want to have a thin panel in the range of 42 - 46inch.And of course for my own technical knowledge i like to now more about this, also because there's not much information to find about it.

It's not an asset where you should invest additional money since there will be no outcome which will be worth the time and money spent.

content: I have a similar action ongoing, I'm planning to reuse the chassis and panel of a broken Philips LCD TV. Mine however uses a LG panel instead.According to what I know the cheap LCD controllers you can get require an LVDS extender, not only for the different LVDS connectors (51+31 Pins) but also for the 100/120 Hz conversion.Still on my desk and awaiting some further work I have an HDVX9-AS V4.2 LCD Controller combined with an PL.MS6M30K.1 converter. You can find them a lot on the usual Chinese seller sites and on ebay.Mine was pre-configured for the LG panel but there is also an option for the samsung panels. If I got it right it only requires some resistors to be moved for the change.Have a further look around and maybe start searching from the panel model number, smaller set for notebook panels are known and partly well documented.My project is not done so I cannot provide you more information.Cheers, Geronimo
