Well don't buy Yamaha as a replacement, they have similar issues with the processor board. I've seen 2 models with intermittent dead problems, and Yamaha won't even acknowledge that it's a problem, go figure.

I created a reply simply to praise macgyver655 on fixing my Pioneer Receiver. I found this thread while searching for an alternative to spending $250+ and driving 3 hours to my nearest repair center to get the beast fixed. After a few quick emails back and forth, we worked out the issues, I sent him payment and mailed my board. As promised, he fixed and returned the now working board back to me (very quickly I might add; maybe 4 days) and I am enjoying a renewed system. Thank you Macgyver for your excellent communication, help, patience, fair pricing and timeliness. I sincerely appreciate your help.

Hey Macgyver, are you still fixing these? I decided I would like to get this fixed. I have a VSX-92TXH. I spoke with you two years ago but I never had the chance to pursue it. I'll PM you.

I was looking over some of my parts orders today and it looks like I've done over a hundred repairs now. Repairs have slowed down since the beginning but still coming in on occasion.

Has surely been an interesting adventure....... Thumbs Up

I might have another one for you, Mac. I've got a minty VSX-56TXi that a guy gave me a year ago to dick around with because it had an issue, and it's just sitting here. Obviously, I'm in no rush... It's a little older (no HDMI), but it's really a nice piece. I know it's getting nice out and you'll be doing less indoors, but if you're interested, I'll try to fire it up this weekend and see what the issue was with it - I can't even remember, it's been so long.

Yeah, it would depend on how much of a hurry your in. Weather is getting nicer so I'm doing much less repairs. Let me know what it's doing and we can go from there.

Macgyver,

I have a VSX-92 with no audio output. Unit does not recognize any digital audio inputs. Video is fine. Generates audio for calibration. I have the service manual, this appears to be an issue with the digital mother assy. Is this a problem you are familiar with? I ask as I cannot locate a replacement digital mother.

Hello, I have the 94txh and the dreaded freezeup just hit. Do you still fix the boards? do you supply the knowledge to help pull the board, how to ship it properly and how to put the little monkey back in. I am so excited to have found this thread, you will or could save me from the local service center with the 2 month back up... thank you in advance.

Mac, seeing how this thread took on a life of its own, you should start your own sub forum here with every obscure thing you've ever repaired. you'd be rich! Smile

Wow. Things that I've repaired. I wouldn't know where to begin. I dont think there is a household appliance, lawn and garden, automotive, street bikes and motocross bikes, heating and A/C, pools and hot tubs(including control units, 3 in the last 4 weeks), house wiring, new entrance service, construction equipment and generators, jukeboxes, boats, and whatever else I can't think of right now that I haven't repaired. But I do enjoy it..

Mac,
Answer me this: what is the temp hi & lo sides in an oven from when the heating element should come on or shut off?

In an oven is set at 350 degrees, and the temp starts to drop, when should the heating element come back on to bring the oven back up to 350, and how high does the temp go before the heating element shuts off?

I cannot get a decent answer on the Internet.

Thanks.

wallace

Yeah, I'd guess you'd get many different answers on this.

First it would depend if it's digital control or not. A digital oven will monitor oven temps to tenths of a degree so a +/- 1 degree would be easily achieved.

A non digital is a different story. The thermostat has a metal flap with points and bends on/off with temp change. Age and quality of parts will also affect but a good rule of thumb is 1% of set temp. So 400 degrees can have a 8 degree swing. This would be a good operating stove. Of course this can also vary from stove to stove.

A bigger problem with ovens is temp drift. Set it at say 400 degrees and it only heats to 375 or 350, or vise versa 425 or 450. This can happen in both digital and non. Fortunately there is an adjustment for this in both styles but in digitals you need the key sequence to adjust it.

Is this what you were asking? Very Happy

wallace -

few things to remember: controllers often have a deadband area around the setpoint (desired value) so they don't turn on/off all the time. You wouldn't want to controller the temp in a wellhouse with a lightbulb in which the switch gets flipped a lot.

Also, the on/off behavior in time and/or wrt to temperature might not be the same. That is, systems (heating systems especially) are not symmetric in their response around a setpoint. that is, an oven might heat faster than it cools as temps near the desired temp.

Also, controllers for ovens can be "tuned" to behave in very, very different ways depending on the application and system requirements. Overshooting the desired temp as you heat might not be tolerable, in which case one has to approach the desired value much more cautiously and therefore more slowly. If overshoot isn't a big deal, one can really race to the setpoint and slam on the breaks, so to speak.

All of that said, if you have access to the controller/electric lines, we can watch the controller with some tools I have when I come for the NEC stuff in a few weeks! Smile

oh, mac's estimates all seem true to me -- and the 1% rule is a a heuristic I hadn't known but it rings true. I might modify it to be 4deg F or 1%, whichever is larger.

Mac and Matt,
Late on the reply, but, here goes.

When I set the temp for 350, the guage will climb to somewhere around 360. It will then settle in and lower back down to maybe 290 before the heating elemnet come back on to bring it back up to temp.

I guess I am looking for, What is the "standard" (if there is such a thing) for the upper limit of the climbing temp, and then the lower temp of when the heating element comes back on?

Is there a percentage that is the industry standard, or a certain degree anount?

Geez, I hope I made sense. (Porbably not...................................)

That is a pretty large swing in temp. You may have a defective oven temp probe. Is it a digital oven?
