working with a de-cased TV

[severdhed]

hey guys, i have a 27" sony trinitron TV (component video)that i plan on mounting in an old cut corner dynamo cabinet i am picking up from a friend.  the TV itself is about 31" wide, because there are speakers mounted on either side of the tube.the inside of  the cabinet is 25.75" wide.  I popped the back of the case off of the TV tonight to measure the actual tube, which is about 25" wide.  This is awesome because it means it will fit.  i am just a little intimidated by this project, after looking at the inside of this tv.  I see that there are 4 metal tabs at each corner of of the tube,which is how it is screwed down to the plastic bezel. in the cabinet, there are two metal brackets at the top of the monitor area with bolts sticking out.

 is it safe to assume that i can use those to hold the tube in place?  or should i try to mount the tube to a piece of wood and then mount the wood to the cabinet using those brackets?

also, how do you deal with the PCB?  there are two circuit boards which are mounted on what would be the bottom side of the TV..one seems to be a power board, the other is for everything else i guess.  there are lots of wires running from these boards to the circuit board on the back of the tube.(is that area called the neck?)  do i try to disconnect these cables from the PCB and remove it separately?  can that even be done?  or do i have to have a few people help me by lifting the pcb out while two of us lift out the tube?

is there a detailed guide for dealing with CRT monitors anywhere?  i know that there are some crazy voltages stored up in there somewhere and that they can kill you if you touch them in the wrong spot...what i would like to know is...where is that spot?  i'd like to avoid it.

maybe this is a stupid idea, but the picture quality is pretty good and it is just the right size...and since i already have it, the price is right.  i just could use a few pointers on how to get this in the cabinet without getting hurt or breaking it.

You will be fine.

Take a look at my cab to see how I decased my tv and mounted it.

I've mounted a few 27" Sony Trinitrons (OK, the presentation/broadcast monitors, no TVs as such) into cabs with no problems. Nice.

There are guides around on how to not kill yourself when disconnecting the anode cap, on this forum and elsewhere. Google & the forum search tool are your friend. otherwise you are pretty much right, so long as you leave it off for a day or so to make sure that any large capacitors (e.g. power filter caps) have fully discharged.

i thought about building a wooden frame, but i'm just not sure if there is enough room..the amount of wood on either side of the screen would be very narrow..i will have to take a closer look at it tonight after the kids go to bed. (it is sitting in the corner of my family room right now, so i have to keep the case on it to keep the kids from being killed). I thought about just building a cabinet from scratch to fit that TV in the case, but that sounds like way too much work for me.

My wooden frame was probably overkill and I probably could have simplified it by just making a sturdy frame that's pre attached to the arcade body.

Hi,

Here's how i did it, it's a big / heavy 27" Sony TV and it works like a charm.

The battens that are holding the piece the TV is bolted on to are glued and screwed to the cabinet sides.

Important: Before you decase the TV and throw away the case, Write down the make, model, serial number of the TV. This is impotant information in case you need to find out how to enter the TV's service mode. This is needed if you have to adjust the image size / position.

Yes, that's the way to do it! simple yet strong and effective. Basically a piece of plywood with a hole cut in the middle, and two battens in behind to support it. Carefully mark the tube mount points before cutting anything.

Nice diagrams, Razzer

[severdhed]

that looks great..im just not sure it will work in this situation.  i'll have to measure the actual tube itself again, because when i measured, i measured to the outside points of the four metal corner mounting brackets on the tube...which was 25".  the cabinet is 25.75"wide on the inside, which doesnt leave me alot of room to play with.

[Zebidee]

Sounds like a perfect fit then. Seriously. I've put 27" Sony screens into cabs with nearly identical dimensions, except with even less room to move than you have. You have a whole 3/4 inch to spare.

[severdhed]

thats encouraging.  i was just worried that if i had to make a piece of wood with a hole in it for the tube to go through, and only had about 1/4" of wood on either side, it woudlnt be very strong.  the cabinet is not yet in my possession, but i can hopefully pick it up here in about a week. my wife said i have to wait until after our yard sale this weekend so we can make some room.

so, when lifting the tv out of it's case, how do you do it?  do you disconnect the ciruitboard from the tube?  or have someone else lift them out while you lift the tube out?

[Zebidee]

Once you have those battens in place behind the wooden bracket (ie the piece of wood with a hole in it), the whole structure will be a lot stronger. I've even seen it done with just two pieces of hard plywood, at top and bottom, as the thin bits of wood you have left at the sides become a bit redundant (although this arrangement wasn't quite as stiff when in situ).

For most TVs you will be best off disconnecting the chassis entirely from the tube, so that you can deal with each part separartely. The only scary bit will be disconnecting the anode cap (with ie with the suction cap) - you must make sure that you discharge the anode cap properly. Also, make sure that you don't touch the hole afterwards, as it can build up charge.

a 25 inch decased tv will fit into an arcade frame. its actually a good idea to check and see if your tube is a crossover to your monitor chassis. if the tube has the same pinout as your old monitor tube,

you can actually save yourself a headache and throw the tv chassis away.

Give me the number of both of your tubes, and i could tell you if the one from the tv is a plug in to your chassis.

thanks.

i'm not sure i follow you here.  i dont have another chassis.  the cabinet i plan to put this in is empty, there is no monitor in it.

Just sharing some pics of a project I did that is along these lines.  27" tv, measured the ohms and got a chassis from 8 liners to match.  I used an arcade mount from an older junk 27" arcade monitor.

Back to the OP, here is how I mounted my 27" Sony Trinitron (professional video monitor) into a cab. The space is only about 58cm wide! That  actually makes it a bit less than 25"! But I managed to fit the screen inside anyway. I have managed to get so-called 29" TV screens into identical cabs as well.

[Garebear911]

I have the same cabinet as well. Mine is the "s back", not sure if yours is. Pretty sure they're the same dimensions either way. Anyway, I wanted to do the same thing. I de-cased it and put a 27" arcade chassis on it. The chassis didn't quit fit between the wooden beams previously mentioned so I moved the top one up and made a little notch in the wood for the chassis to sit. It fit perfectly, doesn't look the best but the monitor covered it up. I was super hesitant to do this as well, having zero knowledge about anything and all... I guess the point is, you can make it work!

[mvsfan]

basically what all these replies are confirming is that if you are out for an arcadevga powered display with no hassles is to see if your true 25" tv tube will fit into a good arcade monitor chassis. if the actual tube itself has a larger or smaller (such as the 24.5, Sold as a 25")  dimension, then you are s out of luck.  same thing if that tube doesnt have the same pinout as your chassis.

otherwise, it will work.

[Zebidee]

If you have a good SCART input TV, then you already have a good "arcade monitor" and don't have to bother with using an old arcade monitor chassis. However, if the TV ever develops a problem, you can always get a recond or new arcade monitor chassis to match from Jomac or 8liners.

[Zebidee]

There is more to matching tubes with arcade monitor chassis than just the number of neck pins. Refer the Monitor/video boards for more info.
