decasing a TV, advice

(1/5) > >>

severdhed:
I have a showcase cabinet i picked up a few years ago, and i had installed a 26" TV, i simply took the back plastic shell off of the TV and set it in the cabinet and it fit fairly well.  However it looked a little small in the cabinet, which  was designed for a 32" monitor.    Anyway, today i picked up a 32" Sony WEGA TV cheap and was excited, however upon removing the old TV, i see that there is no way i will get this to fit without removing the tube from the TV shell completely and moutning it directly to the cabinet.  my concern is how do I deal with the circuit boards to the TV?  they are mounted to the plastic shell of the TV below the tub, there are so many wires and things running around back there, it is a little intimidating to think about disconnecting it...how do you guys deal with this?  I know there are people here who have decased TVs and installed them in your cabinet, what did you do with the circuit boards?

I have never discharged a monitor before, when working with the old one, i was just very careful about where i touched it, but if i have to remove the main circuit board, i am thinking that I almost have to discharge it to be safe.  Can this damage the TV?


Thanks.

capsule:
Sometimes it is possible to decase the tube without disconnecting the circuit board, it depends on the TV. So if you are afraid disconnecting stuff, try that.

Anyway, always discharge it before touching anything, here's a tutorial:


And if you really have to disconnect the board, take pictures and/or put labels so you can easily reconnect everything later.

I made a little slideshow of the process as I did it: http://imgur.com/a/ps64D#26

I have to say that Sony TVs seem to have many more PCB boards and general complexity than the Toshiba I have pictured.

Advice not in the pictures:

* take a TON of pictures of the TV internals before you start taking off parts
* mark cables you remove with a sharpie or something to make it clear where each wire goes.  Labels or color coding might be good too.
* Don't scratch the tube glass then you have it face down, I used some old beach towels
* use the plastic from the TV that holds the PCBs (this is in the pics)
* try to make the dismantling and reassmble steps as close together.  I once took a TV apart then tried to reassemble it a month later and it was way harder than taking it apart then putting it in the cab the next day.
After you do your first discharge, it get easier/ less scarry.  I did my first one with a long ass chicken stick = the screwdriver in my pictures with a 6' piece of PVC on the end.

I don't really recommend this but you can cheat on the deceasing like this:

I ended up doing this and pulling the rest of the case a few weeks later.

I think I have the exact same TV as you, and if so here was my solution.  -> http://forum.arcadecontrols.com/index.php?topic=130287.0



This method may or may not work for you, but it worked very well for me since I need the tv to be facing upwards and was able to attach all of the electronics to the frame without disconnecting anything.  I think the most difficult part of dealing with this TV was the sheer weight of it, as it was incredibly difficult to maneuver without the case on and it would be very easy to damage something... that's where the wooden frame becomes invaluable.  Again, not sure this would work for you but this was my solution with this TV.

thanks guys.  I removed the back cover from the TV last night to take a look at the insides.  This is going to be quite the project.  I measured the tube which is roughly 18" by 22"...the opening in my cabinet is 19" by 23" so it will fit, but just barely.  This means that i will not be able to mount the tube to a wooden frame and then sit it in.  Due to the way the cabinet is designed, i can mount a piece of wood above and below the tube in the cabinet to mount it to..hopefully that will be sufficient.  This thing is just so difficult to work with.  The main issue is that i don't have a garage or shop area to work on it...the cabinet sits in my family room, and since i have 3 small children, i can't really do anything until they go to bed at night. That makes it late to have someone here to help me, so i have to do most of it by myself.  The old 26" tv i had was heavy (120lbs) but i could stick pick it up and take it in and out of the cabinet by myself...but this one weighs in at 170lbs...so between the extra 50lbs and the added size, there is no way i can pick this up and position it in the cabinet on my own.  my plan right now is:


first i need to get a few boards mounted to the inside of the cabinet above and below where the tube will sit, leaving just enough room for the tube to fit through and so that i can screw/bolt the tube to it.

Then some night after my kids are in bed, i will open the TV back up, attempt to discharge it and then remove the circuit boards so only the tube is inside the TV, then put the shell back on before i go to bed so it will not be a danger to my children.

then once i'm sure the cabinet is ready to mount the tube, i'll have to have a friend come over in the afternoon when my daughter is napping and help me lift it into the cabinet and fasten it.  My boys (4 and 6) are old enough for me to tell them to stay back while we are doing this, but my daughter is only 18 months old, she has proven to me on a daily basis, that if there is something stupid to be done, she will do it.  I cannot open this TV up if she is awake in the house.

I'm not sure how to lift the tube out of the TV housing though..it is hard to grab onto and is very heavy.  i'm assuming the best way would be to place the TV face down on a sturdy box of some kind so that the box supports the tube, but once it is unscrewed, the plastic housing will drop down to the floor, at which point we should be able to grab the tube and pick it up..i'm just worried about trying to position it in the cabinet without breaking the neck off, and holding it still while trying to screw it in.

I'll try to take lots of pics and will probably be back with more questions
