Question about Apex Digital HT-150 System

Apex DT250 wont turn from standby (red light) to On (green light)

I have been using the Apex Digital DT250 for about a year without incident...although I left it on for most of that time. Lately I have taken to turning it off (with the remote) so that the green light turns red. This evening I discovered that it wont turn back on. Pressing the power button on the remote makes the red light on the dt250 blink once instead of turning green. Pressing the power button on the unit itself makes the red light flash quickly, at about 5 to 8 Hz.

I opened the unit up. But I don't see anything obvious. The connections all look good...

Has anyone discovered where a bad connection can be located or anything?

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.

I had the same problem and changing the 4 470uf capacitors didn't fix it. I changed C6 which is a 47uf 16v which ended up being the solution.

Converter wont work red light on when i use the remote it wont turn green when i push the red button manualy it still wont turn green


If you're electronics savy, as in replacing capacitors, open it up.. that's your problem.. one or two of the caps on the power board has gone bad.. most likely a 470uf 25v, which can be replaced with a 470uf 35v found at Radio shack for about $1.29. You can tell if it's bad if the top is cracked open & leaking or just domed out instead of being flat.

Apex DT250 converter stuck in standby mode


I just had the same problem and replaced the popped capacitor and it works. I had to use a 470uf 35 because radio shack didnt have any 25's. It only cost $1.59 so i bought 3 just in case it happens again

Need Universal code for RCA remote with Apex DT250 Digital Conver


Use cbl/sat button. Your remote might use more or less than 4 digits. Use 749 or 00749. It'll probably work. It worked for me.
