Hello, We were watching a move and the TV just went black. The power button kept flashing and the picture did not return. Can you help?

It is a good chance you need a new bulb. Is there any cadance to the flashing like 1,3 flashes or 2,3 2 flashes. etc

It is worth getting an estimate. From the symptom you explained, it looks like the horizontal output transistor became defective.

Screen went black

Remove the front grey bottom panel of you TV (don't forget the 2 screws behind the front AV cover located just below the power button) then remove the panel behind the grey panel. You should see 2 heat sinks on the front right of your TV, place a fan near your TV and have it blowing on the heat sinks. Now turn on your TV and see if it stays on longer then it has been. If it does, your DC amps might be overheating. If they are, you might be able to fix your problem by adding in a little more heat sink compound between your DC amps and the heat sink itself. You can find the compound at Radio Shack for about $5. let me know if pointing a fan directly on the heat sinks helps.

Suddenly, the screen shows double images on letters and numbers plus red/greenish like shadows on characters.

Youre convergence Ics need to be replaced. post the model number of your set and I will post the STK number that you need and a link where you can get new replacement ICs

Black screen

Sound like you have problem in two major.

1. Check the if there any short component in the primary and secondery side of the power supply.

2. If the component are ok in the power supply.Check in the deflection area.

Good luck.

No Picture / No Sound

What was happening before can put you close to what when out. If you had color problems or sound, or even picture going small. these are symptoms that causes the set to go out. If color look in the convergence area and look for blown fuses and bad resistors. If just went out the look at horizontal output transistor.

Sounds like you lost the High Voltage. The beating sound is the power supply trying to start up. After a predetermined time it will quit to protect the set. This is a very common problem and typically not that much to repair. If you are not an electronics repair technician you should find a reputable repair shop and enlist their services. I would not think the cost should exceed $150.00 to repair. Good luck.
