Without investigation it is impossible to know what failed. There are a number of boards in that set where there is fairly high current used. It is possible that some components have failed.

The Panasonic service rep would service the set by swapping out the failed modules. If the set is an older model the modules may no longer be available. You can take the set in for an estimate to see if the parts are available, and to see if the set is worth to service.

You may have either failing 24vdc power supply due to bad DC filter caps, loose solder joints, or failing backlight inverter board. Those are the two areas you need to check out.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

There is a problem with your t-con board it is the one that transfer image and get the signal from the logic board if this is faulty or not receiving signal to logic board it will produce gray and white screen try to check the 5volts dc supply and the 12volts supply if you are familiar with the electronic components and have proper equipment you can do it by your self but if not you can contact a technician to do it for you and save you from stress because this problem must be done in actual testing of the unit to check the real source of the trouble. Good day and best regards.

It pops and shuts off when I first turn it on. It finally stays on with sound and grey screen which changes colors. then the picture finally comes in about 20 minutes later

NEVER operate a set after it makes a loud pop. Only high voltage discharges can make such a sound. It is DANGEROUS to operate a set under those conditions. The chassis could be electrified or it could start a fire. Contact a qualified service technician.

Soyo DYLT032D - grey box in corner, no main picture or sound

Tv is on, after a few minutes it goes black and there is no sound. The indicator lamp is still green and stays solid the entire time. Without turning the TV off, in about a minute, you hear a small buzzing...

Someone else gave me the tip as I had the EXACT problem, but no buzzing. Unscrew the panel on the front bottom of the tv. Once that is off, there is another screw that opens a little panel. Unscrew the single screw with an allen wrench and pop out the bulb and casing. Mine was full of dust etc. Used an LCD cloth, but compressed air would do the same thing, put it back together and it works great!

TV with grey screen turns self off

This is an issue with the power supply. The capacitors used are faulty and you likely have to get a new board(about $400.00) or fix it yourself. LG's are quite east to disassemble.

You will be able to tell it is the power supply board due to the cable running from the plug to the board. It will look similar to this38376af.jpg

Next locate the bad capacitor, likely green and about the size of a quarter. You will be able to tell the bad capacitor by the bulge on the top.

At this point you can buy the new capacitor at a local t.v. repair shop for just a couple bucks or likely take the board to them and they should be able to fix it for 10-20 bucks. Unless you are decent with soldering I suggest taking the board in and having them replace the bad capacitor.
You will need a 2200µF 10V capacitor. I may suggest bumping to 2200µF 13-16V capacitor just so you don't have the same problem again.

Once the bad capacitor is replaced, replace the board and turn on the t.v. You should be good to go.

Red Light Flashing 6 times

When the lamp fails in this unit, often the thermal fuse opens. The error code is 6 blinks. To replace this part requires a great deal of deal of disassembly.
