Wont power on

Sounds like you need a new bulb, or possibly new lamp. The red/green flashing is the warm up to get the bulb ready. If it's shutting down after that, instead of turning on, it means the bulb isn't working - that's a common thing, for the bulb to burn out. Possibly the lamp's bad, but that's much less likely.

No picture, can hear audio, timer light blinking then the television turns off

I'm assuming that this isn't a bulb problem - it was replaced when the warning appeared on the screen. In that case i'm afraid that this is the "Green Light of Death" problem, ie capacitors on the DM board have gone bad. To confirm that press Menu and Input buttons on the tv and the timer light will blink a set of 2 numbers - it should give you the 41 code. You will have to open the tv and check and replace them. Some electronics repair experience is required, if you don't have it then it's time to call someone who has it. If you are willing to try it yourself, wait 2 hours with the tv unplugged from the mains then follow this.

Red light flashing screen is green turn off itself

your color wheel/ color main bored has gone bad (red flashing indictating one of 3 things depending on flashing. no power to main board. or to much power/bad board on one of the color boards) or you just need to replace the bulb in it. i doubt its a bulb issue bc you do see a greenness to it at first. but *** will auto shut down till the board is fixed. sorry for the bad news but this is your solution. . if you can tell me what model the tv is i cna find out exactly what it is and how many flashes.

I have a 1994 zenith big screen the picture is showing really dar

It could be that the picture tubes have gone down on emission, there is a prcedure that can be tried to bring up the overall brightness but it is just possible that you will loose some picture quality. If it's a 1994 projo tv i am thinking of the three crt system, a gray scale alignment would probably correct the dark condition in your picture, again depending on how far gone is the emission in your picture tubes, if your projo tv is the dlp system, the bad news is that you could be needing some light engine repair. The color adjustment is possible with the availability of a service manual or in the case of the dlp system, light engine repairs or replacement are available from some on line stores.

Tv not working

Bulb may be bad or the lamp housing is damaged from heat. The plastic housing warps causing the micro switch that tells the tv the bulb is in goes out of alignment and the tv thinks the bulb has been removed

Samsung DLP model hln617w won't turn on (not bad bulb)

Samsung is notorious for having bad color wheels in their DLPs. Well lets just say they are like toasters, they only last a certain amount of time. If the color wheel isn't spinning or is broken, the set will power down almost immediately after you hit the button, you may not even hear the entire fire up jingle. Check the wheel, if you can see the bulb light up for that split second. Actually, check it whether the bulb lights up or not.

Lamp will not light

At first i was thinking the ballast had gone bad but after reading a few other post i think it would be best to call pannasonic..
others forums read:
ballast had gone bad. Panasonic no longer makes these ballasts so mine needed to be rebuilt at the tune of $400.00.

With the ballast in place still nothing so now they claim that they need to order a "kit" from Panasonic which basically is all the components of my tv.
