Maybe the TV is broken.

I have several 37's and 45's all working fine with energy star off.

I have an LC-30AD1E and am trying to read the current digital TV channnel from the RS232 connection.
The manual is a bit ambiguous on what commands will retrun a response but:
ITVD?___ returns the current analogue TV channel
I'd have expected DTVD?___ to return the current digital TV channel but I just get an ERR.
Does anyone know how to read the currently selected digital TV channel from the screen?

Any help much appreciated.

Thanks,

Huw.

This worked for me. We have 13 Sharp Aquos TV's in one residential install that were driving us crazy. After being idle for awhile they'd revert to this power saving mode and wouldn't respond to the power on command. Fortunately, we found the answer here. Thanks for sharing. BTW we sent the RSPW 1 command to enable the RS232 followed by a .3 second delay b4 sending the POWR 1 command. Now the TV's are turning on all the time.

Has anyone tried this on the newer models? I have a LC-46D92U. I have been lurking around a long time and have learned a lot for my business. This would really help on a custom job with an RTI System. The power off and other commands work fine but cannot get to power on.

This solution also worked on the same new model. You only need to send the RS232 enable command once. I suggest putting some delay before sending the POWR 1 command. In Vity software this was simple to do. Unfortunately, am not familiar with RTI.

Claude,
Saw your response and I tried again. Still no luck I have tride both "RSPW0001/r" and "RSPW1 /r". Neither seem to work? Does anyone have any ideas? I can get all other commands to work except power on?

FASTLS

vwpower44's response, quoted above, seems to say you can't send it twice or it will undo what was done. Okay, you say it only needs to be sent once. What if, by mistake, you send it again? And do you understand what he means?

What is Vity software? What particular Vity product are you using (in case they have more than one product) ?

Ernie,
I understand what you are saying that if you send it more than once, you would disable the command. But what would the "RSPW0000 do then? I tried pusing only once the first time and nothing happened. Do I need to send this command before every on command is sent or send only once and TV would recognize them all the time. Some posters also state that you can turn off the Energy Star in the setup, which i cannot find and I am sitting here reading the manual.

For all!

Sharp has a firmware update that will correct the problem of no rs232 on. The information provided was correct but TV needs correct firmware to recognize all commands. Took about 10 minutes to complete. Will need a SD memory card to load firmware update. Sharp knows about the problem and says tech support has been getting many calls on this.

I feel I owe it to the world, after 7 hours of trying to get RS-232 Power commands to work on an LC-52D92U (or LC-46D92U ) I have figured out that there IS a new firmware update on the 92U and 93U series. I spent a very, very long time on the phone with many supervisors who all told me it was not possible, and the TV simply does not support an RS232 power on command, which I have finally gotten to work. The commands are as mentioned in this thread, but without the firmware update, the "power on" command is not listed in the serial database of the TV, so even if you do the Energy Star disable command as listed, the power on function still will not work because its not built in to the TV. I don't know how to attach a file in the forum, but if someone emails me, I'll gladly forward them the entire email from tech support. Please note upgrading the TV is very easy, and at 5 minutes, relatively quick, but it does require an SD card 128MB or less. I used a 32MB MicroSD in an SD adapter without any problems.

I have a similar problem with a LC-37AD5E model. I've tried the "POWR1_ _ _" command (with the TV turned on) and I've got an "OK" from the TV set. It has no effect though if the TV set is in Standby state. Any help please?

any help please?

As of yesterday, I had two Sharp LC42D64U's. I scowered this forum to find an answer. In the back of the manual Sharp does list the proper codes - they just don't tell you how important they are!

As far as Crestron is concerned (I saw the earlier post about AMX from Impaqt Post #3), sending the hex equivalent of a "0" (\x20) will NOT work. In the string for the "Enable Power On" command you MUST enter the command as it was written by many people on this forum.

The proper command is as they stated: RSPW0001.
In the Crestron command sets, i did not make it user accessable, nor do i initialize it. I do it manually ONCE (as previously stated), and now my power on command works.

Thanks to all posting on this forum. Extremley helpful and informative.

I guess if you absolutely had to, you could use one of those IR 110v outlets, to kill power. Convert a selection to IR, trigger the outlet on, then toggle the lcd.


still though, im getting about sick of all this crap myself. They shouldn't make anything anymore without discrete commands.. I mean, how hard would it be?

Hi everyone,
I too am looking for discrete RS232 power on command for a Sharp LC-26AD5E, I have tried the RSWP1 command to switch off the Energy Star but that doesn't help,
Anybody any ideas?????????
Many thanks.
