Hello guys im looking for codes to my old Samsung TV CX-558WT.
The orginal remote is RM104 (IR7476). On my Universal Remote code 064 and 350 it works but the keys do not work as they should. The auto search giving the same effect.
I dont know what code is correct. Please really help me. Thanks.

What universal remote are you using?

URC11C-12A, It works well on other TVs

Hmm... There's a manual for a URC 11C-8/8A in the files section, but the Samsung TV codes it proffers don't include 064 or 350. I subsequently found a 12A manual on Scribd, but as expected the TV codes (seemingly all makes) are the same.

As it stands, I cannot understand how it is you are using 064 and 350 and can only suggest you try the codes listed in the above manuals.

all codes they do anything :/
from C8 and 12A, i trying all 3 letters codes from internet.

Many universal & oem remotes don't work correctly on Samsung tv, no repeating volume commands. They are using the wrong protocol, at one time it was the right protocol, but Samsung changed it. Only few remote manufacturers have a corrected code, UEI is one, I suggest getting ONE-FOR-ALL universal, in it look for tv code 10812 or 10702.

i have question, what about a 4 letters codes?

If you're saying you have UEI made OFA remote that takes letters as a code, then no, its too old. If its another brand of remote, then I have no idea. Test the codes if they don't repeat, you have your answer.

You don't need a universal with corrected code, all you need is a learning remote, teach it the commands from your Samsung oem remote.

yea, but i have too two pilots (first 3 letters codes, second 4 letters codes) for cable, they have universal remote function when im try use autosearch in (3 letters) my TV power off when im click on stand by button, but TV dont wake up when im click this button again :O

I think we need some clarification.

Are you saying you have two remotes - the 3 digit code URC11C-12A and a seperate 4 digit code device for cable?

If the answer is yes, what is the cable remote you have?

Do you have the original Samsung OEM TV remote?

i dont have oem remote, one remote for cable is URC 184001-01R00, remote number two UPC HORIZON REMOTE KWR153705

According to this web page, the URC remote uses a MAXQ610 processor.  That means it is a UEI remote, and if it uses 4 digit codes, you should assign setup codes 0812 or 0702 to the TV device button.  If it uses 5 digit setup codes, use 10812 or 10702.  But I expect it uses 4 digit setup codes.
