Hi
I'm replacing a chip (first pic) but i can't find one with the exact same letters on it, i can only find chips with the first part RTD2270CLW. Could i use a chip like one in the second picture where the first part is the same? Sorry for my bad english

 

Yes you can use it.

 

hi Tim,
Welcome to AAC.
The main part number is the same, the other numbers are just manufacturing batch numbers.
I would use it.

If that chip doesn´t require to be programmed, then it should be ok. The other numbers are things like datecode and batch number.

You got it right there - a basic functional chip is probably OK, but anything containing firmware is a whole nother can of worms.

When in the TV servicing trade; a large Hitachi came in with a corrupted 24Lxx EEPROM. The replacement didn't work, and it took a lot of digging to find out there'd been a firmware revision and the micro & ROM had to be replaced in matched pairs. The micro put it over the estimate and the set was returned to the customer unrepaired and at a loss to the shop. During the course of untangling the web of deceit, I ended up speaking to one of the besuited Australopithecus seat polishers at Hitachi UK, who indignantly informed me their aftersales care was second to none - I simply asked him: "so why are people bringing your crap to us for repair then?!!!".

There's a few other gotchas with chip numbers - clock speed is one of the obvious ones. There can also be functional variants.

 

If my question is answered, should i remove this thread?

Not yet - you might need more help figuring out the data sheets, and what the apparently meaningless appendages on the part number mean.

 

Hello,

The RTL2270CLW can not be found.
The RTL2270L seems to be a flatscreen controller:

Depending which flat screen controller - it may contain factory test dud pixel correction data.

Definitely not, a lot of google searches lead to this forum, and a lot of times just by reading the thread people can get the answer they needed.
