Removing the TV casing tutorial?

[sofakng]

Are there any tutorials out there (preferrably with pictures) that explain how to take the case off of a TV?  One of my main concerns is the anode that stores all the voltage....  I don't even know what it looks like...

DO NOT REMOVE THE CASE FROM A TV if you do not know the simple principles around it.

Unlike an arcade monitor, the chasis in a lot of TV's (Especially older ones) are HOT!!!

Well, my TV is a Toshiba 27A33.  This might be my ONLY option other than loosing $200 and buying a new TV.

Is it really THAT difficult and/or dangerous to remove the casing?

The TV is brand new and as far as I know it's a very recent model (it has component [is it composite?] inputs -- it's the one that HDTV uses)

the tv casing is just a large plastic shell covering the back of the tube.  You can generally remove it without coming anywhere near the anode--I just tip them down on their face, remove the screws, pull the plastic straight up (removing any coax/rca/s-video connections) and set aside.  Now you have essentially an arcade monitor with extra parts--TREAT IT WITH RESPECT as its still dangerous--Once its been discharged you can remove the other half of the case as needed.

there was a talk recently about TV's vs arcade monitors.

The gist that I got out of it is that TV's (unlike arcade monitors) do not use isolating transformers, and the frame is HOT!!  So be careful.. never touch anything while the back is off (unlike arcade monitor that does allow you to tune it while the back is off)

Go to this thread on some brief info pertaining to 'hot' and 'grounded' chassis's in TV's.
Great info on isolation and step down transformers.

Thanks for the link... That explains a little bit, but it doesn't really explain what you need to do to remove a TV casing or how to discharge a TV.  I read somewhat using a resistor but I'm not sure how to do that exactly.  I do have a multimeter as well, but I really need some pictures to look at so I know what I'm doing.

Any links for something like that?

Read the FAQ--how to discharge is there, as far as removing the case--undo the screws, remove the case  Really unless your tv is some weird setup its just that easy (and if it is weird we really need more info before advising on a course of action)

The Monitor FAQ at the top of this forum?

It only seems to cover discharging monitors...  would that still cover a television?  (eg. would the process be the same?)

[menace]

yep--there are more parts inside a tv naturally but the principle is the same--and for pity's sake-PAY ATTENTION TO WHAT YOU ARE DOING.  it's not difficult but it can be dangerous--if you have any questions just post back here.

Besides whats listed in the Monitor FAQ... is there anything else I can buy or do to protect myself?

I think Bob Roberts sells something to discharge monitors...?

Actually, (most) arcade monitors DO work on hot chassis, and that's why you MUST connect them through an isolation transformer, which then of course makes them "unhot", with respect to earth ground that is.

I will post more later, as I've cracked numerous TV's and computer monitors.

However in summary, unless you're working on it with it plugged in, don't worry about it being hot or needing an isolation transformer.  Also, unless you're separating the tube from the electronics (chassis) board, don't worry about discharging the monitor.

Your greatest problem decasing a TV is GRAVITY.  The tube is heavy and has a very strange center of balance and wants to tip and tug where you don't want it to. Your second biggest problem is of course the vacuum and related implosion/explosion if you don't handle it well and you could at least break the tube neck and ruin it, or worst, break the bigger side or front and suffer a very bad implosion and flying glass.

Think about those things BEFORE you even worry about voltages and stuff. (not that they're not important, but you have to consider more than just that)

I'll post more later, but you won't need anything more than screwdrivers, perhaps a socket set, a wire or two and gloves, at the most.
