Standby light on, but won't power on

SOURCE: power short/ bad fuse?

I had the very same problem. The dreaded blinking power light. I also dabble in electronics. I found that all that was wrong with mine was one bad cap. There are two 1000uF(microfarrid) 16V(volt) capacitors in the mid section of the power board, right next to each other. One was bulging on the top. They have an "X" on top. I replaced it with a 1000uF 35V capacitor from Radioshack. They did not have a 16 volt. (Never go down to a lower voltage) The capacitor I got was larger than the old one but I gently moved over the parts around it and got in there. After replacing this one capacitor, which I got for $1.72 tax and all, I plugged it up and no more problems! It works great! I hope this helps someone else.

I had the same problem, red blinking light after owning for several years. I decided to replace the capacitor at C914 to see if it would work, and it did. Apparently that capacitor is prone to failure. Since this seems to be a common problem, I created a web page detailing the repair. Hope it is helpful. Repair cost $1.39 + tax.

Change the audio amplifier IC are on short circuit and that´s the cause your device goes to protect mode

Mine was exhibiting similar problems. It was the electrolytic capacitors in the power supply board.

There are 4 or 5 of them, and between 2001-2005 there was a bad batch of capacitors that came out of the far east, some of these capacitors were inferior quality so they dry out and fail. You can read about them on badcaps.net You can usually tell a failed electrolytic because the top cap puffs out slightly. Mine were actually almost pointy on top.

If you have the dexterity, soldering pencil and time, you can fix it yourself for about $5.00. Be warned that as soon as you open the case, you void the warranty, so if you don't feel comfortable, take it to a professional. Also, My remote is dying, so if someone wants to sell me their remote, let me know.

The DT250 has one or more bad 470uf 25v capacitors. You should replace all four. Look at some of these youtube videos for how do do the replacement.
