Hitachi 32HXC01 - another Vestel joke

Re: Hitachi 32HXC01 - another Vestel joke

Hi guy's. I'm after a bit of advice. I've been looking for a replacement 17MB82-1a 23111172 to replace my dead board (PSU and LED Board appear OK) but can't find anything available anywhere.

If I get a 17MB82-1a and swap out the 2 eprom chips would this be enough to get it to power up? (or is it likely to be the winbond bios chip's that have failed)

TIA

Re: Hitachi 32HXC01 - another Vestel joke

Got the Tv here, I was able to get it to fire on by heating the mainboard I copied the firmware on to a usb through NVRAM download in the SM and reflashed it (spi flash chips can be temperature sensitive) after reflashing it and letting it cool back to square one. So time to keep diagnosing

Also someone has tampered with the Psu and broke some traces on it so got to fix that as well

Ok. So, when you receive the tv, you can post an image of model of panel, to see if it's like this (LC320DXJ-SFE1):

Ok but, you know, my english is not very good.....Don't know if I'm going to understand you, or if even you are going to understand me...... But.....don't you think would be better to open a thread and share your experience? Then, we can show people how to make dumps of those eeproms.....and how to write a file to an eeprom.

yes of course i understand

I like your (comptek)post about the 24" Bush being as good as new, this set in all its different disguises only just made it out of the shop before blowing diodes,these should have come with a bungee cord fitted to the back, to return them back to were ever they were brought from(most will have an Argos sticker on it).

Re: Hitachi 32HXC01 - another Vestel joke

are they cheap? not sure if i have anything with a paralell port lol

The programmer is soooooo chip!!! But.....you have to do it by yourself!!!! And, if you don't have a parallel port computer, you can ask a friend....

There's another option of an usb programmer, CH341A, for a price of about 3 dollars (search on ebay).

The test clips socket adapter has a price of about 4 dollars. Do you think it's expensive??? You can try to do this:



Maybe you think it's dangerous to solder wires on eeprom pins...... Let's see:

[QUOTE=Augustus;611022]You need 2 things:

- An spi flash programmer. I have used this one with success (it works by paralell port):

Re: Hitachi 32HXC01 - another Vestel joke

This one had 1460 hours on it ! But 275 is a fucking joke !

Re: Hitachi 32HXC01 - another Vestel joke

sorry its fully working i just wanted to know how to copy firmware incase i or other people needed it at some point lol

You need 2 things:

- An spi flash programmer. I have used this one with success (it works by paralell port):

- SOIC8 SOP8 Flash Chip IC Test Clips Socket Adapter (or to solder one wire to each pin of eeprom):


And, of course, the program for make the dump. I have used this one with success: http://rayer.g6.cz/programm/programe.htm#SPIPGM

Two things are important on vestel tv (and, in general, in all tv): the panel, and the main board. If you have a dump of both flash eeprom of an especific vestel tv, would be useful for other one if the panel and the main board are the same. I think the main thing is the model of panel, while main board is maybe not so important if they are not exactly the same (less or more usb or hdmi, etc). Of course, I'm talking about 17MB82.

Fixed the one I picked up today Shorted 24v diode, replaced all output diodes and all is good

Then, you can make a dump of both flash eeproms.

The 32HXC01U uses a 17IPS19-5 Psu and 17MB82-2 which is slightly more reliable then the 17MB95S-1 boards in my experience.

Re: Hitachi 32HXC01 - another Vestel joke

Hi, like other people said, it's possible you have a corrupt firmware, who is present on two flash eeproms.

Would be good you post a complet image of the main board, and a image of the model of the panel.

In the main board, what is the serigraphed reference (I think it's a 17MB82-X)?
