I am thinking more along the lines of the pop you hear being a high voltage discharge (that should not be happening). The source could be one of the several thick red wires which you should NEVER touch. The focus divider block located at the front lower right side under the speaker cover. You can unplug the set and inspect that for a crack. If cracked, you must replace it. Although this one is Toshiba, RCAs are really bad about that. You must be very careful, TVs have many dangerous voltage sources that can injure and potentially kill. If you are unfamiliar with TV servicing I would take it to a shop.

Why does the red indicator light flash but the tv does not come on? What do you think could be the problem?
These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. Viewing it in "Mosaic" or "Magazine" will make surf easy.

Heard a pop, tv went off, then doesnt come back on
Your unit has some sort of PSU fault, or a problem that is shutting down the Power Supply Unit, PSU. This happens so that no further damage, and possible fire will occur. The sound is it starting up, shutting down, over and over.

You need to take the unit to a reputable service centre/man and ask for a firm "Quote" for the work to be done.

Picture & sound go on & off every sec, red light blinks 5 times
helloFive blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Your color wheel needs to be changed. Mine just did the same thing. I changed mine, and the buzzing sound went away, however now my picture washes out with light or yellow colors. The darks look green and purple also.

In our area this is commonly the cable boxes. Does it occur on DVD or other sources? If not:

Popping noise
Our Sony (almost new) is experiencing sound problems. The sound go off and on about every 10 seconds. Cords appear correctly connected. It sounds as if its coming from the television.
Can you help with this problem?
Thanks,

Toshiba TP50H15 Rear projection TV - Sound drops in and out The sound will come on very low and then after a period of time it will "pop" back to normal. Some times it will go very low and again, after a period of time, will pop back to normal. It's not distorted, just very low volume. Is there a PC board with the amp on it that needs to be replaced? Thanks
