    CH341A programmer

    hi,guys.

    trying to find more info on this usb ch341a programmer....what 8 pin blank eeprom is the best or universal for tv programming....there is so many kinds that i don't know witch is the best...and yes im just starting with trying to program my own eeprom since im in the tv repair business and it starting to cost money and time of shipping to finish the job.so if i could program them myself it would save a lot of time waiting for part to arrive.so my questionne is:

    -is this programmer ok or sould have something else
    -is the a standard 8 pin eeprom for most of tv or have to have different for all tv

          You will need to do a mod to it there's a flaw in them that powers the chip at 3.3v but the data lines are getting 5v. https://www.eevblog.com/forum/repair...727#msg1323872
