Dear all,

I have a Sharp LCD ( LC26P55E ) with RS232 all commando's works great.
But only the 'Power On' not...

I already try this :
Send command "RSPW0001" from PC. (Enables TV to use ON command)
Send command "POWR0000". => TV turn off. 4. Send command "POWR0001". =>
TV turn on. And if send "RSPW0000". => Shift to "Default" can not turn on TV with RS232

But without a good result... Who could help me?
Thanx

ps. with all other rs232 commands works fine...

This is some infomation 39 Cent Stamp sent me that helped when I was having the same issues with Sharp RS232.

Menu/setup/standby mode/Mode 1 Should be enabled

Mode 2 offers power saving but causes the display not
to come on via rs-232 power on command.

I didnt send any strings to it to change modes.


This should fix it!

Iain,

Thanx for your reply, I tried but I couldn't found it in the menu...

Maybe a secret menu??

or maybe a other solution??? Anyone have a tip?

The problem i was having was that the TV has energy saving settings that, when set to a specific mode, cause the TV to go into 'deep sleep' and RS232 cant wake it up.

Do you have the manual for the TV? If not try downloading it with this link [Link: tradenet.sharp.co.uk]

It appears, from the manual, that your menu may be slightly different. Hopefully you can navigate the confusion and find a menu with power settings that will allow you to solve the deep sleep problem.

Check page 14 for Power Management information. According to the manual it looks like the factory default may be to have the power saving settings OFF. And its quite possible that the manual is talking about something completely different and more confusing :). Poke around and see what you can come up with. Good Luck.

Adding... I didnt have to go into a secret service menu but anything is possible and your model may require you to do it. Im not aware of the steps to get into Sharps secret service menu (if it exists) though.

We had this problem too. What you've got to do is turn the unit on and send the following hex string, ONCE ONLY, to turn off the Energy Saver mode.

52 53 50 57 30 30 30 31 0D

Worked for us. Unfortunately, if you turn it off with the IR remote after this, it forgets and puts energy saver mode back on after about 30 seconds.

So lose the IR remote!

Hope this helps.

Thanx, I will try it tonight!

Thanx for your reply!
I will let you know if it also worked for me...

your enable command is wrong

it should be this
RSPW1 CR

there are three spaces between the 1 and the carriage return

which 232 controller are you using?
that will turn it off permanetly

sorry i ment that will turn off the energy saving mode permanently

btw, from my documentatation your power commands are wrong

they should be POWR1 CR for on
POWR0 CR for on

noticeagain the 3 spaces

I use a AMX controller for rs232.

Your right about : POWR0 ,cr ect. In my program is that right.
Everything works fine exept the ON command.

I give it a try to using RSPW1 CR and will see if then the ON command will works... Else I think it must be done by IR... but I hope this will work!

Thanx! I let you know...

Try RSPW1___CR - underscore equals three space characters.
In URC speak that would be RSPW1\x20\x20\x20.
Actually RSPW1 command is power save disable.

RSPW1 \r
This fixed the problem for me on a LC65E77UM.

Thanks.

FYI, I been working on the newest Sharp 80" LC80LE661U opening up the RS232 port on the LED TV. There are two step to make the the RS232 active. First, turn on the TV with the remote control, go to the "menu" hit the menu button, tab over to Intial Setup tab. scroll down to the Quick Start Mode and turn it "ON". this function over rides the energy saving mode. The second step is to send the comand 'RSPW1 ',$0D or 13. I was using SP control NRC to control the the sharp 80" LED TV. I hope this helps

Thanks for this info.....Changing the Quick Start Mode to 'ON' fixed the remote RS-232 Power ON command. I was stuck on that issue for a little bit, but your suggestion fixed that problem. I didnt have to use the 'RSPW1' command......but I am using HEX for control.
504F5752312020200D = Power ON
504F5752302020200D = Power OFF
