This is an OnkiotX NR5007 which is a giant home theatre receiver with more channels and you can change the more kilograms to get along. It also can work and apparently it's got this all to common Onkiot issue where you just don't get any sound anywhere, even very, you seem to be operating normally. So usual of this means that there's a bad BGA on one of the boards in the unit but sometimes you can get away with just doing a factory reset so let's just start with that. And that does not seem to face the issue so now we've got to have to have it take this finger part and have a dig around and off comes the cover. And if we just have a quick look at the unit before we're getting to any repairs it certainly does look like a quite competent amplifier. We've got no less than one, two, three, four, five, six, seven, eight, nine amplifier boards with a quite proper heating and big toroid or transform it to gear with it. So this thing is this transformer so almost on par with a one you get in the Yamaha P2200 series that's my thing impressive. The power rating for this thing must be up towards a kilowatt under full load. There's a little ton of transformer so it's probably for a preamp stages. I don't think we should be anywhere in here because this guy is usually the one who causes all of these issues on every on here this kind of generation ever. I've never seen a page apply problem. I've never seen a power amplifier problem. I've never seen a logic problem or anything except for people having ripped off the HDMI connected software board and this guy having bad solder joints and perhaps one actually having a bad chip. So I'm just going to be crude about it. We go from experience and resolve this thing first thing I do. And if you're curious what chips labeled Q3 thanks and one and it's a Texas instrument TMSD830K01AZKB. YFA9983ZLW and it's clearly some kind of decoding chip since it's got the DTS and Dolby logo on it. The chip's cooled down so let's give everything you're going to see. If we'll don't the on-key magic trick again. And Tyler has expected. So now all we've got to do is make the heat see convatic guys so that it doesn't happen again and send this guy on his way. Sweet. And while we have the opportunity here's a bit of a close look at the power amplifier sections. Very tidy, very high quality. Probo advise pots on the top there. And we may now put the voices on label the TTA. Fripple 0, 2 and TTA Fripple 0, 3. Made by Toshubba, 1 per rail, per channel. And all brand name caps of course. We may seem to be. Chemical branded 75 volts, 22 fans in microfarads. So this is going to run with something like a plus minus 60 volt supply. It probably has some kind of supply switching integrator given the number of relays down and how you can select the speaker impedance of a menu. And there you have it. A cheap, fake, fun, expensive piece of kit. And no market worker can enjoy his probably multi-faxing dollar stereo for a couple more years. Thank you for watching.
