If you have some garbage in the main processor you need to leave it unplug for 40 MIN, to reset it back to normal. If that don't work then you need to check for a shorted horizontal transistor, mounted on a metal heat sink near the fly back transformer, that is what turns your high voltage on.. If that is good , then the next common problem would be is a bad convergence module, and you are looking at around 400 on repairs.

seems like a power supply problem inside the tv and when the transformer gets warm it is giving you problems you might have to get a tech seviceman to come out and have a look at it as it is not a job you should do yourself when it comes to replacing the power supply hope all goes well

While it is suspicious happening so soon after lamp replacement, your main power supply may have failed. In earlier sets, these were problems that eventually happened.

WHEN I TURN ON THE POWER THE THE RED LITE COMES ON


We have a TV that does this after we have left it off but plugged in for awhile when we go on a trip. Just unplug the TV, wait a few seconds and plug it back in. If it's like ours, you'll find that resets it.

My Polytron TV is on standby mode. I used the remote but wont turned off


When you turn that TV "off" with the remote it go's into standby mode, that is the way they made it unfortunatly
To actualy make it not have any power going to it you will have to unplug it or plug it into a power strip and use the switch on the power strip.
They use the standby mode to allow the TV to turn on quickly without making you wait.

My emerson tv standby light is on the power light flashes twice


Mine stayed in stanby mode and all I had to do was to switch the plug to a different outlet. The power strip it was on wasn't providing enough power. It worked fine for a month before I had a problem.

Red led stays on after turning off.


Aren't you talking about the standby led? cause that is perfectly normal... when it's on it means you can turn the TV on by remote, usualy it goes away when you turn the TV off manualy by pressing the OFF button on the set, but is this really your problem?
