Hi.
This is a shot in the dark. I'm after a particular variant of the software for this chassis. It's complicated, I'll give you a heads-up.
I have a 22 inch TV-DVD combi using MB62 Vestel Chassis. Unfortunately I did an update to the most recent firmware and now discover that the new firmware is for the wrong tuner (Sony instead of LG). Guess what? I don't have the original
. With the new firmware it doesn't tune at all, just goes through the motions and finds nothing, all other functions work though.
This chassis also has the majority of service menu items read only, so can't change it there. I've got hold of quite a few software files for this chassis, however so far the best one I've found has the correct source options and tuner but the wrong panel type. It's tolerable but I'm concerned it's overdriving the LCD, not to mention that it starts in French on the initial set up menu.
During my messing I managed to brick the board and had to remove the SPI flash and program it up in an external programmer (heavily modified so it would recognise the 3.3v IC in my 5volt programmer.) I'm now at least back where I was with it booting up and accepting firmware files, and fully functional aside from incorrect options depending on what file I use.
So after all that here's the questions........
Does anyone have any files for this chassis that might be different to what I have? Each variant is named mb62_en.bin. I'm basically after as many of these as I can get hold of. I've built up quite a lot of knowledge on this chassis now, as you will imagine there is not much info available out there for these products. I'm at the stage of examining the raw HEX code on the files I have, it's a tear your hair out situation, trying to find subsets of strings that differ between files similar. Then of course it's dawning on me that some code will be instruction, some data. So it may be more likely impossible the way i'm going with it. The alternative is to build a kernel and modules which will allow me to customise options. This involves cross-compiling not to mention I don't actually know what MIPS processor is being used, pure linux hacker terriory and I'm not sure my brain will allow me to go that far!
Well anyway there's the upshot, and believe me the story is much longer than this. Any MB62 files you may be able to acquire would be gratefully appreciated.
As a parting gesture I have a collection of these files, together with a RAW dump of the SPI flash, and a lot of knowledge gained during my exploits. If you're doing battle with one of these you are welcome to give me a shout to see if I can offer any assistance. I used to hate them but in reality it's actually a nice chassis, the lack of support lets it down.
Cheers everyone.
Ask any questions, I tell no lies
