EEPROM Programmer

Re: EEPROM Programmer

Well I'm guessing and think I'm close but I get a read verification error as seen in the pic and happens on both boards so I think I must have something wrong.

Re: EEPROM Programmer

Ok I think I have the software installed from link above and drivers and software does see the device so good to go. My first project to try. I ordered a main board for a VIZIO from eBay and it arrived yesterday however it has the audio port torn off and another part missing most likely from being a little rough removing it from the donor TV. I believe the original board has the chip messed up as it's stuck on logo screen. What I would like to do is take the image off the one that came in the mail and see if I can't put it on the original. I do not want to remove the chips and I think the Jtag clip I ordered extra should do it??? could anybody walk me through this? I do not see the correct orientation of how to put the clip on the chip either.

Re: EEPROM Programmer

I thought I started this thread? LOL My new toy came in the mail today. No software so what is it called and where can I download it? version 1.18???

Do a search for RT809F drivers and software, either on here as it's popular with those that program laptops or a wider internet search, there seem to be plenty of links and resources.
1.18 is for the CH341A programmer.

Re: EEPROM Programmer

im using version 1 18 as well ive read a few lately where versions 28 onwards are causing read/write issues

Re: EEPROM Programmer

Gotcha thanks. So I don't need the adapter then correct? Can remove from PCB and put on to the programmer without the adapter?

One thing is I don't see where the software would be used to program. Do you download off a website?

There is a guy in China i think that sells the latest software for $10 or there are links to older versions on this forum. I use an older free version 1.18

Re: EEPROM Programmer

Well, i'm really comfrotable with the clip, not much used for now this prog. but always worked, much time saving.

Re: EEPROM Programmer

It's designed to clip onto the chips whilst they are still mounted to the board.
It's much better IMO to remove from the board. They are then soldered to the other PCB with headers that then goes into the programmer. The chip is then removed with hot air and put back on the board.

Re: EEPROM Programmer

So that spring loaded clip and connector is needed for 8 pin eeproms or does it just hold them better?

Re: EEPROM Programmer

The difference is the spring loaded clip and connector board.
I bought one but always struggled to get proper contact with all 8 pins so quickly threw it in the junk drawer.

What's the difference between that one and this one? Is the adapter needed?

Re: EEPROM Programmer

You recover the old chips? Good...

Only if they are good.
I do replace if i feel they aren't 100% though.

Re: EEPROM Programmer

Or erase the old chip.

Re: EEPROM Programmer

Erase the new chip...
Yes there are some Russian videos for this model of programmer.. (very boring but useful..)
there is also a site in Chinese you can translate, with a forum with example on many chip types..

Re: EEPROM Programmer

Not struggling yet. Just ordered the programmer above and never did a chip before. I need to know where to get the bin files then maybe a step by step with the software. I'm not a n00b to TV repair. I always just bought the pre-programmed chips but thought I could save a bit of time and money especially time because everyone wants the TV fixed TODAY! and do not realize parts need to get ordered sometimes. Years ago I messed with re-programming satellite cards so not exactly new with programming either. If we can get some pro's to chime in maybe this can be a sticky instructional thread?? I would also be willing to pay for private help if necessary. I also hope to lean how to reprogram a bios in a laptop as some I get are locked. I work for Midwest Electronics Recycling and am in charge of repairing what can be repaired and re-sold.

No need to sticky. Find bin, remove chip from board. Place chip on the reader. Read and save the original bin. Erase the chip, program with the bin and verify. This step is repeated by some and the bin compared but I don't. Resolder the chip, done.

Re: EEPROM Programmer

getting the bin files is the hard part as they need to match the mainboard and lcd panel used in the tv there is a recently new thread here with some bin files and links https://www.badcaps.net/forum/showthread.php?t=59877
regarding your programmer i see theirs a few youtube videos that may help you get started
