Look in main menu for convergence and see if it will adjust--if off either adjustments or a bad chip---picture will look 3d and red or blue outlines around lettering etc.

There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both. That POP you heard was likely a capacitor blowing!
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom (look for discoloration of the circuit board around the base of the capacitor) need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the unit will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and/or inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are SURE it's only doing supply output ripple filtering,
and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors, amplifiers, computer power supplies and motherboards, and other electronic equipment.
The parts are cheap, and skill required is minimal.
A great parts source is Digi-Key, and you can order the parts online at www.digikey.com
They typically cost under a dollar a piece plus a flat shipping rate.
The parts usually arrive one business day later.
If you watch the third video, you will see that even someone with no soldering experience can perform these repairs as demonstrated by the woman in the video.

You need to look with a meter at the resistors around the chips, they are usually gray in color with bands that denote value--a good guess is one or more were taken out by the chips--in these sets they will look fine---typical is 1.8 ohm (brown, gray, black bands).

At least one is open (bad--no reading across--like checking a fuse) and there will be several with identical color bands on them.

Let me know if I can help.

If this told you something you did not know, rate this solution as very helpful as I do this here for free.

This is a very common problem among Toshiba & Mitsubishi RP TV's. It is caused by the circuit boards not communication with each other. The fix is about $600-700 with labor, parts, etc. I would suggest getting an LCD or LED TV.

No.Fix.Tv have dead parts on the tv convergence board.Tv colors lines R,G,B mis alignment,can't move any colors lines.The tv convergence board the 2 STK convergence ICS and some or all it resistors are dead on the tv convergence board.These parts,must be replaced on the tv convergence board to solved the tv picture convergence problems.The shop,will cost u like $300-350 for parts and labors.

this unit has a hyper module in which quite a few electrolytic caps are bad,board is no longer available but if you know someone who is good at electronics it can be repaired.all the caps are surface mount and should not be attempted to be replaced without proper training.

the convergence issue can be usually repaired by replaceing both of the STK392-110 Convergence amps and the six 1.2 ohm 2 watt resistors. You can get replacement parts at the following link with instructions on how to replace the ICs.

As TVs age, the rate at which the CRTs begin to decline in terms of light output increases. If you go into the customer menu and adjust the color setting to zero. ( no color) observe the image. Is it good gray scale? Or, is the image still green tinted? If so, its definitely a problem with the CRTs( picture tubes) You may need to just re-adjust the screen settings for the CRTs or it may be more serious, a CRT may be bad. Replacing the CRT is a job for an expert and will cost $500-700.
