I was watching t.v. and all of a sudden I heard a very loud ''Pop", and the t.v. shut off. When I turned it back on, I discovered that I no longer had a picture, but the sound was fine. I could change channels, but 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.
SOURCE: No picture, hear sound, television will shut off after a few seconds.
Take out the bulb (back left hatch door) look to see if the element inside the bulb is broken or blackened - (replace bulb) if the bulb looks OK then it's the ballast that fires the bulb (service call).

The blue tube might be leaking coolant in the high voltage area, that is the cause of the POP. This repair might not be a DIY because of the lethal high voltage surrounding the CRTs tubes.
The slow response from the remote could be because the coolant has affected the main board where the IR signal are going to the remote sensor.
Let me know if you require further assistance.

If you have a Sony DLP, then the loud pop you heard is your lamp. The lamps last approx. 4K-6K viewing hours. Read your manual for replacement part number to reorder and very simple to replace yourself.

Following up on my Feb 7 post. My new lamp arrived, and I replaced it and it works great. The old lamp had many shards of glass come out of it. It was tore up. I saved some money buy purchasing just the lamp and not the cartridge. It's a little bit more work to take apart, but saves money. Mitsubishi wanted $289 for the lamp replacement kit. I got a lamp for $114. TV is working just fine now!
