Re: Onkyo TX-NR414 doesn't switch on

My NR414 came with a remote with typenr. RC-834M. My SR803's remote (RC-620M) works on the NR414 as well, so chances are Onkyo remotes are largely interchangable.
You might also try to get hold of a...

Re: Samsung S24D390HL flashing on and off - wrong power supply ?

I doubt the erroneous behavior the monitor is showing is actually caused by firmware corruption. The phenomena the firmware error causes are described in these threads:

Re: Philips HTS9140 3d Bluray , Which caps needed?

So the pcb in the pictures is not your board? If it is, you might want to check connector CN4001 (bottom right), judging by photo 1 it has a bent pin inside the connector. Beside that, the board's...

Re: Does anyone have a ( 18CV8P ) programmer

So, it's not a GAL, but a PEEL PLD. Looks like the P at the end of the chip type designation just stands for 'Plastic' (i.e. the IC casing). As long as you obtain a (NOS?) substitute of the same...

Re: Does anyone have a ( 18CV8P ) programmer

Is this a GAL? If so, an (ancient) HiLo ALL-07a takes AMI and GOULD PEEL18CV8, Hyundai HY18CV8, and ICT PEEL18CV8 and PEEL18CV8Z. A (just as ancient) DataIO Chiplab takes these as well, with...

Re: Onkyo TX-NR414 doesn't switch on

It looks like Onkyo didn't use identical relays in the 609 and 838. You can easily deduct the relay's coil voltage from it's typenr. My 414 has a SDT-S-109LMR2 built in, the '109' designation...

Re: Onkyo TX-NR414 doesn't switch on

I'd check the specs of the relay in your amp to make sure the coil resistance is OK. If it's a 9V type the 330 Ohm you measured sounds right, so the error probably resides elsewhere. My TX-NR414 had...

Re: Onkyo tx-sr606 fluorescent display not working

Depressing the top part of this connector unlocks the wires inside the connector, so you can pull the flatcable out. This type of connector fooled me as well when I had to fix my TX-SR803 a few years...

Re: Help checking correct substitute for KMB2D0N60SA mosfet

Hi All,

I finally got around to order a replacement mosfet. As was kindly suggested, the Vishay item indeed turns out to be a valid drop in equivalent for the defective Korean one. As they were...

Re: Help checking correct substitute for KMB2D0N60SA mosfet

Checking the standby PSU schematic and the datasheets I noticed every manufacturer has a different way of numbering the mosfet's pins. Denon calls the gate pin 3, drain pin 1 and source pin 2. KEC...

Re: Onkyo TX-NR414 doesn't switch on

The old relay has a snap-on lid, quite easy to remove. I opened it up just to see if anything was visually out of order. Nothing by the looks of it, so I presume there must be a short somewhere...

Re: Onkyo TX-NR414 doesn't switch on

It appears the relay was indeed the culprit. I ordered an identical one on AliExpres, cost incl. shipping approx. 4,50. A little more than a week later the replacement was delivered to my door.

Re: Maxxter ACT-WNP-RP-002-W wireless repeater/accespoint fixed

Really? I wasn't aware these are standard, as they are so small. They're about the same size as the 1000uF/10V cap. Good to know, though, that they are not likely to fail. We'll see how it goes.
