Re: tv wont come on
You may have some type of short INSIDE of your TV .Your TV is trying to turn on and RESETS itself to try again. If you have an EXTERNAL [black box],(usually means power supply, power adapter,etc.) power supply, that!! could be at fault. not giving the proper voltage, current, causing the machine to fault. If you can exchange a known working power supply to see if that is the problem. If you don't know what you are doing, don't go inside of the TV. There are circuits that can hold a charge of electricity that can & will hurt you.

I have the same exact problem...for a few weeks the TV would turn off and the red power light would blink. Then the other day I started having exactly the problem you describe...green screen for a few seconds and then total shutdown.
It is rear projection TV that use 3 picture tubes of red-green-blue to show color picture on tv front screen. Do you see standby red light blinking when TV shuts off after showing blue image for a while? If red standby light is blinking, please count it how many times it blinks, there would be 3 seconds pause between blinks so count pause to pause and post it here to find out possible solution. Thanks.
Sounds like you have a problem with the green crt. That is the one I've most commonly seen fail first. Your tv has three picture tubes in it that can be accessed from the front of the set. The picture tubes(crts) have a filament inside the neck like a light bulb has a filament. Over a period of time tiny particles burn off and the debris can cause a short circuit from one piece of the filament to the other. The tubes are no longer avail. as a new replacement part but the tubes in your set can possibly be saved. One trick is to lightly tap on the neck of the tube with an insulated post or screwdriver handle. Right when you turn the set on and it goes green sometimes you can lightly tap on it, (the middle tube) and knock the debris free removing the short. If that doesn't work the tubes can be rejuvinated/cleaned using a machine found in most repair shops known as a picture tube rejuvinator. My experience is that this procedure should cost 100.-200. plus service call. Most service people will tell you that this is not a guaranteed fix, but 90% of the time it works and you can get years of more use from the tv. Good luck, Russmann.
after holding down the menu and device the led will blink a two digit error code such as 3 blinks pause then 4 blinks then repeat that sequence a couple of times. Need that blink code to help let you know whats going on. The 34 code means lamp abnormality which translates to the power Pwb capacitors have most likely failed.
your set has indications of several problems. red green and blue. indcate convegence issue. the fact that the picture is concave is a indication of totall loss of covergence power supply. the convegence menu missing idicate loss of some voltages from what know as the flyback.AND SHUTDOWN. indicate further problems. generally when convergence fails ..not always the set wont shut down. it could be a simple issue but further trobleshooting would have to occur to narrow it down.
