help needed with easy touch tv
labrat:
hi ive got got an easy touch et071 tv
i think thats its got a faulty eprom
symptoms include menus coming up as green/blue and flickering
control buttons on side doing other random functions (chanel up now powers off)
no picture on any input
sound only on coax input
its got a cv109h board in it which apparently is known for the u7 chip failing which is apparently the eprom
the lcd is a lc320wxn screen with a lvds which appears to have the same part number
it does have a usb service port which is good as i have no eprom programmer.
if anyone can give me any advice it would be great ive not run across this make before so i beleave its a rebadge but im not sure of what
if anyone can give any advice such as service menus, eprom tips or anything like that i would be very grateful
failing this ill just have to strip it and sell it as spares...

try resetting the eeprom the chip your looking for should be a 8 pin starting with 24c.... solder 2 wires onto pins 5 and 6 . join the wires power up tv shut down and disconnect. remove wires rebuild and test.

hi thanks im pretty sure that it seems to be the one marked on the board as e7, the thing is it doesnt seem to start 24c
it seems to start with k32v
shorting pins 5 + 6 doesnt seem to work
jimca007:
its possible your right in indentifying the eeprom however 99 % of eeproms I've come across have always started 24 something or another
If you're absolutely sure the eeproms the chip you think it is you need to look up the data sheet for the chip and find out which pins are the data and clock pins these are the 2 you need to short out... its not impossible your right but as I said in 20 years the only eeproms I've ever had to reset have almost all without exception had the 24 prefix..... theres all kind of producers and all kinds of variations in chip usuage so double checking your chip number and data is an absolute must before you go shorting anything

thanks sorry about the long replys i cant read the chips very well my eye sights now at around -6 so its a little tricky
