I have a 50 inch DLP samsung and it wont power on after making a lot of noise (I replaced the lamp) worked fine for a few days now the red light and the right side green light is blinking. any sugge

The answers above are correct. It's either the lamp or the color wheel. Testing the lamp is pretty straight forward. Use an Ohm meter to see if the it's filament has continuity. It's unlikely that a good color wheel would fail immediately after changing the lamp. Look to see if some wiring is out of place and rubbing the wheel causing the noise you described. A jammed but otherwise good color wheel would cause the TV to shut down and display an error code.

  • Reset component settings. Usually, the problems you encounter with a projection TV may be resolved through the resetting to its factory settings. If you experience inaccuracies in the color, reset the television's PerfectTint/PerfectColor capabilities. Simply press the Menu tab and then highlight "Perfect Color" using your right key arrow. After this, press "Enter" and then "Reset" in order to reset to factory settings. If you have audio / video problems (VCR or DVD player), simply press "Menu" and highlight the "Reset" option.
Reset television controls. In case you cannot fix your TV via its component settings, there are other ways of resetting. Just select "Menu", key in "1, 2, 3", and then press "Enter." In doing this, the TV's manufacturer's specifications will all be restored. If your TV's power system does not function, you should perform a complete system reset. You can do this by clicking on Reset System button located at the TV's control panel. Your television will be turned off and then a green light (LED) will quickly flash for approximately one minute. Once the light has stopped flashing, your TV should immediately turn on.

Green LED always on, power switch has no effect

if using a box or receiver in line with the set unplug those as well. I assume the red light on the set is not coming on or a light is blinking?

The power light is just blinking red on my panasonic 1080i hdtv. cant even switch it off using the power button. picture and sound come on for about a second when the tv is switched on after power cord...

The power light keeps flashing and the tv won't turn on. If you unplug for a minute and hit the power button it sound like it is coming on then it shuts off and the red power light flashes slowly. The TV is a Panisonic 1080i HDTV, about 6-7 years old.

My toshiba TP50H15 color tv comes on then off and the light blink

The flashing power light on those Toshibas is usually caused by capacitors on the power board having failed solder connections. I have fixed them before by removing the power board and resoldering the capacitors. If you have experience with soldering and electronics it is an easy repair. Most shops will recommend replacing the entire board since their labor to repair it would probably cost more. Toshiba put out a service bulletin on this issue which a good technician should be aware of. (If memory serves the capacitors are C109 and C110.  Since your TV still turns on you probably haven't blown fuse F860 which often blows when these capacitors act up.)
If you would like further help with this please post a comment back here.

Here's something that might also be useful. After you turn on the set, and get the regular red blinky lights, hold down the Device and Menu buttons together for about 5 seconds.
The Power light will start to flash in a two digit sequence.
For example, 3 flashes, then 7 flashes = 37.

Here are the error codes, and the corresponding problem:
12 = No error detected, check power supply.
32 = Lamp Cover is open.
33 = Air filter cover is open.
34 = Lamp abnormality
36 = Light Engine (DMD or Lamp Fan stopped)
37 = Exhaust or Lamp Ballast Fan stopped
38 = Lamp Temperature High
39 = DMD Temperature High
41 = Short is detected
44 = DVI cable between FMT and Engine disconnected
