Sony RM-VLZ620 remote

MaskedMan · Post by **MaskedMan** » Thu Jul 29, 2010 1:35 am

This recently released rm-vlz620 remote from sony is UEI made.

It uses 5 digit codes, the prefixes are weird, 5****= tv's, 1****=blu-rays, 7****=cd players. the rest of the code is UEI.

It uses 9** codes to program the remote, but they are weird as well, 933, 905, 977???

I was looking at pdf's of recently released remotes to find one with blu-ray codes, started jotting down the codes and none looked familar until I got to samsung 10199 & sony 11516, this uei made remote!!! So I ordered the remote tonight it will be here next week. Some have had problems with learning, due to the instructions, So I wanted get it anyways.

Of course, you know what the one piece of info that we want to know is!

The RM-AX1400, VL1400, PL1400 all had an internal 6 pin header and all used the uPD78F0547GC processor.
RST Reset signal input
FLMD0 FLASH writing signal
FLSI RXD6 FLASH_WRITE signal input
FLSO TXD6 FLASH_WRITE signal output
Gnd
VDD +3V
Have never gotten around to see if they can be used with a JP1 cable as such. Will see if there is anything in the service manuals later.

What do you mean by "internal 6-pin header" ? Do you see any tell-tale signs that these are UEI remotes? The uPD78F0547 chip is an NEC chip, so that would tend to say that these are not UEI remotes.

If you can tell anything from the service manual, you can download it from RC files. They have the service manual, the manual, and codesheet.

I purchased it from Amazon, using amazon prime and still won't show up until the Sept 4th.

If anyone wants it quicker, you can get in Best buy.

Does it really have two menu buttons?
And what exactly is "SYSTEM CONTORL"?

in previous sony remotes system control keys held macros.

To save you having to look for it, it's here: RM-VLZ620 at Remote Central
While the instructions don't look like UEI instructions, the setup codes *are* UEI setup codes, so I would be very curious to know what the PCB looks like when you get the remote.

I'd also be interested in seeing if the dyslexic "SYSTEM CONTORL" button is indeed so labeled!

I can't take a picture worth a damn, there are no pins or pads. If you want #'s off the components I will wait 'til to put this back together?

And it doesn't have this mispelling of control. And there aren't two MENU keys, the two white keys are RECALL & MUTING.

I thought you were good at taking pictures, don't you often post pics of remotes side-by-side.

I take good pictures of zippos, i sell on ebay. All I have is pink casio point and shoot exilm i bought for $60 on woot. i can't take clear close photo for you to read the #'s off the components.

try this photo

or this

Edmund, you're right. Those pictures stink!

The first pic's not bad, the problem is the flash obscuring some of the PCB. The best way to take a pic like this is to do it during the day when there's lots of natural light so you don't need the flash.

Wow, that looks very different to what we typically see.

There appears to be a sub-board which may be hand-soldered(!) to the main PCB. The sub-board has 40 connections, and presumably carries the microprocessor.

There are also two 8 pin chips, and I'd like to know the numbers on those chips. Perhaps they are drivers for the LEDs.

Apparently there is a 5 pin (2 pins not connected) reset chip, which is typically used to reset the micro (and other components) if the supply voltage goes too low.

Do you see a IR receiver for learning? It looks like there are 3 IR emitters.

Compared to the UEI PCBs that I have seen, this one has quite a bit more cost in it.
