I have a mitsubishi wide screen television. I heard a loud pop noise, and now I have no picture. what is the problem?

If you have a projection TV, you have likely lost a bulb. Don't worry, it happens from time to time and it's really easy to fix. Just Google the model number of your TV and projection bulb. Sometimes they come as just the bulb or the entire assembly. Purchase the whole assembly if you don't feel comfortable taking things apart. In the back of the TV there is likely a small door that opens (Possibly with a screwdriver), the old assembly will slide out and you just have to replace it with a new one. A bulb can run anywhere from $50 to $120 but it's inevitable that they will burn out like any other bulb. At least they are easy to replace.
It's also possible that the sound was a capacitor blowing. This happens more frequently in the summer because there are electrical power fluctuations due to Air Conditioning. You can search Youtube for "Capacitor Explosion" or "Blown Capacitor" to compare the sound. If that's the case it will need a repair.
If you know someone who can operate a soldering iron it should be an easy fix. There will be a very obvious blown capacitor on the main board of the TV and it will just need to be swapped with another one. If you're not paying for labor this is going to cost you less than $5 in parts. Google "Badcaps" for instructions on replacement.

Philips TV making a strange clicking noise

A model number would be helpful to answer this but:

This clicking sounds (no pun) like either a mechanical relay in the set's power supply or possible arcing somewhere in the set.

These sets also have a shutdown feature that if engaged may sound like a tic-tic sound.

Let me know model number which is not indicated on this question here.

My tv has lost its colour, and its green or yellow sometimes.

Okay that means the other GUNS went out when i refer to guns I mean the other blue and red, they need to be replaced pretty costly but if you value that TV I'd do it.

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

Jvc pd35b50bu no brightness

Hitachi 46F510 different channels are different brightness and to get them viewable I have to run the brightness so high that you can not see any text at all. Also all white areas are blasting white bright. Edges of the tv also seem darker. I am connected to a cable system.
