Mounting TV in Cab

[WhereEaglesDare]

When mounting a CRT TV in a cab is it easier to load it from the front, incase I want to pull it out, or will it be easier to install it in the back and strap it down.

I was thinking of building a type of cage for it so I could load ir thourgh the bezel area with some cloth handles (that will be hidden by my bezel art) and it can rest against this cage I wanna build for it...  What do you guys think?  Does the rear of the TV need to have room to get air moving for cooling or is that less important?

arcade monitors are usually mounted from the front or top ( cocktails ) .  build a solid mounting frame depending on the size and weight of the tube. sometimes a plate to rest the chassis is a good idea , makes maintenence a lot easier. if the wires are long enough the chassis can also be screwed on the inner sides of the cab . i would allways advise to take the tube out of the plastic case. the dismantling procedure can be done by a child.  

ur new tv to arcade screen doesnt need more room than in its natural habitat , but make sure the heat can get out of the cab . ventilation holes plus fan in the rear or top of ur cabinet prevents breakdowns in hot summer days .

Awesome response!  Thanks, I may need to make some kind of adjustments cuz the screen in it is 25" and the one I wanna put in is 27".  Plus I have to fab some sort of mounting bracket

make sure you have help.. 19's are'nt to bad to handle by your self but a 25 or 27 inch is a hand full.. and very easy to damage if you uncased it.. which i would.


better to have hep and not need it then to need it, not have it and end up with a busted set.

[WhereEaglesDare]

good advice,

how do you handle the power button?  my set doesnt power on on its own, you have to hit the button to send the power on signal to the board.  can I just short that button out to be powered on whenever power is applied?

[Beretta]

hmm that i dont know.

very "set" specific.. i've heard some models you can change it to power on automatically if you get inot the service menu (the hidden one from the factory not the end user one)

some have been able to get them to come on by sticking a tooth pick to hold the power button in.. or just shorting it.

i believe one person hooked up a IR transmitter and was able to get the computer to send a single to turn it on.
this might also work hacking the tv's remote.

im sure there would be a way to send a pulse from the computer.. or you could wire the power button to a double pole momentary switch.. assuming your going ot wire the pc's power button up to a momentary also could turn tv/pc on at the same time.

probably a bunch of ways' i can't help you with nut and bolts specifics.

For my set up I use a complicated device to manage this.  You may have heard of it - a remote control

In a similar question: Does anyone know how to get the TV to automatically turn onto the 'AV' channel (channel that displays composite/scart etc.)? My tv will turn on if the power button is depressed and the switch at the mains is turned on, only it will turn onto the last remembered channel, i.e. 0-99, and not the AV channel.

Try searching on google for the 'Hotel Mode' of your TV. Most tv's have a hidden menu (used in Hotels) to set the default channel when switched on.

You know, I never considered checking into service menus.  I wonder if there's a way to change this on my JVC.  I've been using WinLirc with reasonably good results forever, but if I could simplify, that would be even better!  Less stuff running in the background is always a good thing.

I'm using an old Sony Trinitron 20" CRT (Model no. KV-21T3U). After searching around online I eventually found a code to input using the remote while the TV was on standby to turn on the 'Service Mode' (pic attached), I dont suppose you know any way to turn on hotel mode from here?

What is WinLirc? Does it let your TV turn on into AV mode?

Thanks!

I wired one of these wired into my AV button to "change the channel" after power on:

The device is powered by my PC, and the PC and TV power up at the same time from an energy-saving power strip (PC is the master).

Winlirc is software that will allow a computer to send and receive IR signals over compatible devices (many of which are an easy DIY build).  Built a serial based unit and have it send the signals to power the TV on and switch to Video-1 once the front end has started up.

http://winlirc.sourceforge.net/

Oh wow!  After no updates since 2006, they just released a new version of WinLirc on May 5!  I just downloaded it and it has been rewritten to support other hardware than just serial.  BUT, since the coder doesn't have serial on his computer, it might not work.  If not, just grab 0.6.5 and you should be good to go!

Where you using TRANSMIT.EXE to send the signals?  Im going after this same route for a solution to Power TV and change VIDEO input...  thanks!

I have an AHK script that runs at login.  Here's the pertinent details.

Code: [Select]

  ;Start WinLIRC
  Run, C:\Emu\WinLIRC\winlirc.exe
 
  ;Turn on TV
  Run, c:\emu\winlirc\transmit JVC_AV-27230 PowerOn 9
  sleep, 3000
 
  ;Switch to Video-1
  Run, c:\emu\winlirc\transmit JVC_AV-27230 Video-1 9
  sleep, 1000This is not a perfect solution, but it works pretty well.  The problem I have is that sometimes the TV comes on but doesn't change to video1.  Sometimes it doesn't turn on, but that's pretty rare.  If I had a wired method, I would DEFINITELY go that way!

Good luck.

[Justin]

Brilliant, thanks!    

By the way, do you know the correct usage/syntaxis for TRANSMIT.EXE?  I have found nothing online.  Obviously you are using it correctly, so can you share with me the instruction on how to properly use it in command line mode?    
"transmit.exe -?"
   does not yield any help....

Thanks!

I don't remember where I found the syntax.  I'll see if I can't locate something in my backups.  I forgot to include an important part, though.  You will also need a config file for transmit.exe to know what command to use.

Ok, I found it hidden within the README file.   

Code: [Select]

WinLIRC

Please see

        http://winlirc.sourceforge.net

for information regarding this program.


transmit.exe was written by Scott Baily <baily@users.sourceforge.net>

usage: transmit remotename codename reps
reps is an optional number of times to repeat the code (default=0).

It is public domain, since the code is trivial.
Mainly it is an example of how to send commands to winLIRC
from your application.

transmit.cpp is the source code for transmit.exe
It uses only windows API functions so you should be able to
compile it with any win32 C++ compiler.  Just be should to include
the appropriate header file (#include <windows.h>).

To compile transmit.exe with MS VC++, create a "simple win32 application"
then use this code as the main program.


If you're not interested in modifying the program the only interesting files are:

winlirc.exe

transmit.exe (optional) commandline program to tell winlirc to transmit a code

*.cf (configuration files for remotes)

So, the syntax is:

transmit remotename codename rep

You have to give the .cf file name which is the definition for the remote you are using for your TV.  The codename is what you have defined in the begin codes...end codes section.  Rep is the number of times you want the code sent.  Since IR isn't perfect, it's typical to repeat the code a few times.  I think the max is 9 times.

Thanks you, are a gentleman and a scholar

Well, I just checked and my particular TV is not yet deciphered on the LIRC site.  I looked all over the web for remote codes for my TV, and nothing came back.  I obviously need the raw hex codes from what I can see.   I will see what I can figure out.  This is very good info thank you!

I got winlirc and a Transmitter, and have it all working now... thanks!!!
