I am sending a feed ripped from a working TV. It is for the matrix as in the topic in the A2 version (with the A1 version, the colors will probably be mixed up).
However, there is a problem with it: the original Manta has GigaDevice 25Q64CSIG memory - and it works OK. After copying and uploading its content to the Winbonda 25Q64FVSIG TV turns on, but hangs on the Manta logo. I have no other GigaDevice memory to check if the batch actually reads well (so far I have had no problems with that). Maybe it's still a matter of choosing resistors between the processor and memory (another manufacturer)?
Hello. I have a CD in A1 version, today I put in A2 version and the colors are really wrong. There is really something to do with these memories, the desoldered memories on both discs can be read, but you cannot erase them or write anything to them - checked on two different programmers. The primary fault is; turns on and stands on the logo. When I try to upload to Winbonda, it does not turn on from standby. You will probably have to look for the original clean bones and just upload the batch. Anyway, he is still looking for a batch for the A1 version.
After searching, I found a GigaDevice 25Q64BSIG memory. After programming with the previously read batch, the TV started and works OK - previously transferred memory contents are 100% functional - checked.
When it comes to mixed colors, to check, you can enter FACTORY SETTINGS through the MENU sequence (with the remote control) -> 1 1 4 7 option: PANEL CONTROL -> LVDS TI MODE set to ON or OFF. Unfortunately, it is not possible to save the changes and after turning the TV off and on again, the picture will appear in wrong colors again.
if you turn the TV off and on, the picture will be mixed up again.
How to bite it, probably the modification of the feed remains, for me a higher driving school or getting the original one. If any of my colleagues has such a reliable charge, I will gladly buy it, I do not want it for free .
Virtually all new Manta (series 40 .., 50 ..., 55 ... 95 ...) have GigaDevice -25Q32CSIG or 25Q64CSIG memories Winbond memories do not work properly with these TVs, only use originals.
Today I uploaded the contents of the original memory, which I managed to read on the new GD25Q64CSIG cube and soldered this memory to a working board from the A2 version and of course the same effect as on the client's disc - it is attached and hangs on the Manta logo. Thus, it is 100% fault of a damaged charge. Maybe some of my colleagues have and would like to share, maybe for a fee? Please write to PW.
The discussion revolves around the search for a V400HJ6-A1 panel and HK-T.RT2957P63 board for a MANTA television. Users report issues with the TV hanging on the MANTA logo after power-up, indicating potential problems with the SPI memory. The original memory used is GigaDevice 25Q64CSIG, which works correctly, while attempts to use Winbond 25Q64FVSIG result in failure. Users share experiences with memory programming, suggesting that only original GigaDevice memories should be used for compatibility. Some users are looking for a reliable source to obtain the original memory or a programmed charge, with one user mentioning a sale on alledrogo for a programmed charge related to the board. The discussion highlights the importance of using the correct memory type and the challenges faced when substituting components. Summary generated by the language model.
