My image wavers when it's hot, doesn't stay cool very long
So my dad used to have this TV and it never had this problem till right before he gave it to me. Unless the room is freezing, the tv will get hot very fast and then the image will start to freak out. It happens with any input. It just has to be on for more than a couple minutes. And it has tons of space behind it. What's wrong with it?
ANSWERS:
"Hi,
One quick and dirty way to narrow down the problem area is to purchase a can of electronic freezer spray. If you use this with the narrow straw like applicator that usually comes with spray cans you can ""freeze"" individual components to see if the TV restores to normal picture. Do not flood the area, be sparing in how you apply it. You are trying to isolate the problem component.
Initially try to determine whether a component is ""hot"" or just warm to save spraying too many components. Place the back of your hand close (definitely NOT TOUCHING ANYTHING) to get an idea of the radiant heat being given off.
BE SAFETY AWARE! THE TV IS ""LIVE"" DO IT WITH ONE HAND BEHIND YOUR BACK (only half joking - that way you will not have one hand accidentally touching something live - which is bad enough - and the other touching something else that you shouldn't)
The ones covered in metal do run warm/hot, that is why they have heat sinks to disperse the heat. Remember electronics can run warm and even hot.
It may be trial and error but then again you may get lucky.
After freezing the correct component, the TV should behave normally. When the effects wear off it will return to being faulty so you can determine by freezing it again whether you have the correct one or not.
It might be prudent to have a mirror in front of the TV facing to the back where you are working. That way you only have to look up and over (or around) the TV to see if anything has happened when you spray.
Here is a link to what I mean. You may have to source something similar from your local electronics shop.
Do one or two components at a time, give it time to have an effect before moving on that way you will not be confused as to which one may be the problem

SAFETY FIRST! Remember to disconnect the power before touching anything in the back of the TV"
"jeffjeffjeff145 the first board is your power board PSPF561A01A I'd expect that to be the warmest since it does most of the work. 2nd board is your Y-main board LJ92-01399A 3rd board is the LJ92-01398A X-Main Board. From what I can see the caps etc. look good. I am missing your main board, Ysus board as well as the buffer boards. Most importantly the filter board B10N2010A. take some power reading on the main board. Follow the block diagram for that. The waiving and sound distortion sound like a bad cap/IC problem will be to hunt down the proper board. You'll need a multimeter to check on some of the connectors. Let us know how far do you want to go with this. The heat coming of the panel is somewhat odd and would require more of an investigation as well.
This image should show you most of the boards"
