One day we were watching tv and the tv went blank. a few minutes later it cut back on manually, but then cut back off and has not turned on since. i tried resetting it by unplugging for 15 seconds and then plugging it back up, but nothing. all its doing now is the power button is flashing green. i was told this is an error code, but for what??

make sure put the lamp door back before trying to turn it on because they have switches on them that allow the tv to turn on. If that is ok you probably have a bad ballast. Call a local tv repair shop to further diagnose the problem.
1) When the picture "stops", does the standby light blink at all?
2) Can you post the model number please?
Some of these sets are known to have problems with the picture tube as it starts to age. There are some workarounds for this that can extend the life of the set for a short time. Without the model number though, I can't confirm that this set is in that catagory. Please supply responses to the issues above and we'll continue from there.
I believe there may have been some parts that were burned out due to high voltage. There are cases where insects such as lizards penetrated and got stuck then got stuck then got electrecuted inside. You can open the back cover of your unit or better, refer to the repairman.
For the first one, please list the model number and count the blinks. Also, can you please post each problem separately. It will get too confusing trying to address 3 sets with different but similar problems.
I have a 42" LG LCD TV and just experienced this today. Watching cable,
then the screen went to black, but audio continued. I pressed the guide
button on my remote and pic came on with my guide menu. But then went
to black again 10sec later and has remained that way for nearly an
hour. Tried switching off both cable box and TV, disconnecting and
reconnecting cables, but no luck. Finally unplugged mains, waited a
minute, then turned back on. Everything seems normal now after the
Jar-Head, bad news, the picture tube has a mild short in the green cathode, tech can come out and try to restore it but it`s usually a futile attempt on sony tubes, sorry to be the bearer of bad news, BMW Rider
The problem might have started because of loose conections in the vertical circuit,if the vertical circuit fails completly the screen blanks out to prevent a line being burnt in the picture tube so that part is normal but the problem is still in the vertical circuit.Maybe the IC just went bad all the way and it might have taken a fusible resistor.
If you are familiar with tv service you have a place to check but if you are not too familiar be safe and call for assistance from a servicer,is a straight forward problem and it should not be expensive.Let US know how it goes or if you need more information.
