Re: Eeprom dump thread!

does anyone have Eeprom files for Philips 48PFA4609/98 Firmware

I was saving a copy of the working EEPROM .bin files to post over here but the files which were only reading a 64kb size, re-read and re-save another copy still 64kb size, after that, I proceed to erase the file and reprogram back using the files save previously, the tv seems not responding any more!!

so, anyone has this particular model dump files??

ps. normally how big is the size of the dump files from a working tv??

Have anyone came across this Sharp-LC37A33M
i need its power board schematic whis is mark as RDENCA288WJQZ

many thanks

I have this acer AL1715 S witha a missing Green Signal color, monitor will turn on normally with NO missing color, when menu button press, OSD came out normally with NO missing color.

But when monitor vga cable plug in a tested OK display card, monitor pic become bluesiest. when menu button press, OSD is perfect with its color, i can see RED, Green Blue at the color setting menu. if i try to set the Green color setting, i cannot notice any changes compare to Red & Blue setting

I have check the PSU board - all seems to be working fine with 3.3v 5.0v 12.0v stable,...
