Redlight of Death Repair

**MarsArtis** · 22-01-16, 18:20

Hi guys,
need and help.

Yesterday my second DUO appeared affected by RED light death.
Today I replaced the capacitor (as by first post in this guide) but the RED light was still there. Tried a second capacitor just in case the first one was not ok. But had no luck.
What should I investigate further?
Receiver keeps the red light up, the internal HD spins but the display stay off and the DUO won't start.

The regulators may be faulty

i wonder is it worth it if you cant do it yourself on an old slow receiver?

H4R7/I in my box, gives only 0,68 volts, but how to determine where the error is..? Is it one of the regulators, and if so, how to determine which one..? Any ideas..? What is correct output from the regulators?

well it lasted a whil, but now got the RLOD again,
I noticed caps C14 & C15 on the psu board have slightly domed at the top - any body know how to test the psu while unplugged from the m/board?

**omega99** · 21-10-17, 11:35

pulled both c15 supposed to be 1500uF measure around 1950uF & c14 was about 2189uF
