He might also think you're smoking pot. lol This all makes me appreciate my crapola Gateway. It's a P series and I bought them in large part because of the bogger screen. I can almost see it YIPPEE ! It has alot going for it really, it has two HD bays which I never seen in a laptop before or since, the RAM is easy to get to, the batteries seem pretty good considering now they are over five years old. But the OS is Vista Hoe Premium and I cosinder that it runs like shit even though it is pretty clean. I mean I don't load alot on it lke some people. The AV is AVG. And the sound sucks. I don't mean the speakers, I mean even the audio output is highly upcompressed, like radio. In fact so compressed - AM radio. Has decent frequency response but I have to turn the input level amost all the way down on VLC to get rid of (most of) the compression. Actually I like it for movies that way, but music ? I might have to get an external DAC. (don't start that audiophool shit now) I dunno what to do, I don't want 7, 8 or 10 and I'll never find drivers fro XP, the running of which has its own set of problems. Not quite ready to jump to Linux but im not completely in the dark on it. Anyway, all this kinda makes me wonder how they manage the heat in those tablets. The Microsoft one is supposed to be a veritable PC. With the USB you could concievably plug in a mouse and (real) keyboard and do just about anything. Even print. One thing I haven't seen them tout is a video output. I am pretty sure it would have to be HDMI because of the thickness. (or would that be thinness ? Like what is the speed of dark ?) Would an external touchscreen monitor work on one ? Ifit had HDMI and USB, probably I would think. |

avagadro7@gmail.com: Aug 11 04:29AM -0700 AE6KS those grippers are cuttable nicely anchoring an Amazon Otter Samsung5 ...... the 1705E's fan left fan went out. An English site gave the screw by screw takeapart. I was surprised finding no access plate....intro laptop. I was involved in a new mixing room project at a major yum yum pie factory. One day several gnomish bakers came in milling around the entry double doors where dough carts would come and go...soon a burly suited man dragged a tall thin man in bounced him off the floor several times shouting waving his arms pointing at the door, grabbing the thin man's lapels ect then throwing him out you got it....the new door was in a major wrong place in a new finished wall. |

One day in a cardboard box factory the boss grabbed me and told me to make a drawing of the die room where the new rotating storage rack system was to go. (kind of like that conveyor your dry cleaning goes on only industrial sized) He was VERY clear. He did NOT want it to scale. He wanted it in an hour so he could generate a contract. Do NOT waste time drawing it to scale. Probably told me 3 times. But if you know the dimensions, it's just as fast to draw it to scale, so I did. Turned out the rack system couldn't fit in the room! We had to redesign, but catching that mistake saved the company a lot of time and money. (not that I saw any of it) |

Phil It's inside a piece of heatshrink sleeve bigger than I've got to replace it with, but on the blown out one, you can still read "4R7" so I guess 4.7 ohms which would be about right. Assuming that they have it done, I suppose I will have to get a length of suitable heatshrink in so that it's restored to the insulation levels that it came out of the factory with. I was able to just about get my meter across the bridges after the tranny wires had been pulled, just to make sure that there were no issues with them or anything south of them, but all looks ok, so I think that it is just the tranny primary short circuit for no good reason other than it felt like it ...

Be far better to slip a piece of silicone tube over the thing, as is often done with NTCs. > pulled, just to make sure that there were no issues with them or anything > south of them, but all looks ok, so I think that it is just the tranny > primary short circuit for no good reason other than it felt like it ... ** You gotta hope the new one does not get that same feeling, or the other one in the amp. For my XLS602, I used a "pre-loved" toroidal tranny that was on hand, with a similar main secondary winding and added a small 18-0-18 E-core for the low voltages. Might be smart to get a quote for a replacement tranny made to suit that Crown. ... Phil |

Other than the 4 amp fuses on the rear of the unit, his chances of fixing it himself are low. Having said the obvious, if there is sound at that channel of the volume control, the fault is most likely an output IC (STK0050II) or driver IC (STK3062). New old stock replacements are rare and Chinese counterfeits are likely to perform poorly if at all. Mark Z. If it has Output ICs instead of discrete components; just throw it out, they are not worth fixing any way. I would have thought that on older model Onkyo would be discrete. Shaun |

And unless such are readily available and/or there are valid substitutions, it is emphatically NOT worth fixing if they are blown and you would have to pay someone else to diagnose, order parts, install the parts, test and give back. On the other hand, fuses do get weaker with age and strain. It may well be that one or another of them is blown. DO NOT rely on visual inspection to determine if a fuse is good or not. A fuse that fails from age typically does so at the solder point, and that would be invisible. Check with a VOM, or simply install new fuses. If one is visibly blown, however, try to look for a cause before plugging in a new fuse. Also, DO check solder joints both on the input and output side. Also at any speaker switches. One simple cold-solder or broken solder joint can condemn an otherwise good component to landfill for no good reason. http://olx.pl/oferta/tuner-onkyo-tx-3000-CID99-ID9nSKW.html This is a picture of the guts, clearly showing the driver and output ICs. From my seat and with my eyes, it looks like a STK0050-II which is an off-the-shelf item usually selling in the US$8 - 12 range, or so. Maybe even less. Search for eBay item: 121715396881 as one readily available example. So, check for mechanical issues. Check for obvious problems such as a loose wire, poor contact at an RCA jack or output connection, the usual suspects. Check _all_ fuses. Then, if all else fails and you feel that replacing the modules would not be beyond your skills, purchase two (2) and have-at. The second one is if the 'other' one goes bad in the future. Maybe even keep a spare driver IC if you really like this beast. I would offer to fix it, but between shipping and the 90+ days it would take me even to get around to it, you are far better off staying local. Trevor, my heaviest tuner is 11.7 kg. My heaviest amp is just a hair under 26 kg. It's funny - my 200 WPC SS amp weighs only one kg. less than my 75-WPC tube amp at 24.9 kg. Peter Wieck Melrose Park, PA |
jurb6006@gmail.com: Aug 10 03:43PM -0700 I got bad news and good news, though you already heards, it has ICs. The good news is that if it didn't make any nasty noises, it is probably just the speaker fuse. More good news is that if it cannot be fixed, a preamp level output can be had because the tone controls are separate from the power amp. What's more, the bad STK could be faked out to get a ittle bit more gain out of the STK3062. Not my favorite approach but would work. The 3062 is probably good, and if not there were enough of those around and not failing that it would be easier to find NOS. I can rework it to take more modern chips. The FM is decent, has four gang tuning which is better than most. The chipset and design overall are good. All you need is a power only amp. But change those speaker fuses first. They are usuallly under a rectangular cover on the back wiht one #1 phillips screw in the middle. They go simply from fatigue sometimes. Or if someome connecteed too many speakers to it. Tell you this much, if you are lucky and it is just the fuse, change them both and then make sure to only use one pair of eight ohm speakers on it and make sure not to cover the vents. Keep it cool. If those STK power ICs have lasted this long they will probably last alot longer. If they are bad I can retrofit new ICs in there. It would technically no longer be an Ohky amp but you still would have the Onkyo tuner and preamp. It would be easy to get pre level outputs but putting the amp in there would mean you can still use its internal speaker switching. I cna do it but shipping from there to Ohio and back would not be cheap and you have to pack it as though it is going to be handled like a basketball, because it is. I retrofitted a Mitsubishi Interplay system for a guy in Pittsburgh and the round trip was $300, AND THEY UCKED IT UP ! It was insidious damag3 so a claim would be just too much trouble, plus what wuld they pay ? So we met at the state line and I fixed it and met again and everyone is happy. Shipping was rally high because that is a heavy unit with a (half decent) vertical linear tracking turntable. Your unit would not be as much, but you are really too far to meet. The other thing is that on eBay they go from about $100 down to $32. But there is only one for sale now and it is for repair or parts. The $32 one, some people are not too bright and have a really short auction and don't put a reserve on it. Boss just did that with a vintage echoplex machine, I'll have to have a talk with him about that... If you need and want this done, probably around a hundred bucks plus parts (probably fifty), and shipping both ways should be about a hundred. That is more than the thing will bring. If you like it allt then it is worth it. If not, don't throw it out, sell it to someone. Even for parts. Sometimes a knob can fetch $25. To get really good money you have to part it out and list all the goodies separately on eBay, or let someone do it. You can probably get decent money out of the good STK, if one is bad. So don't just throw it in the trash. |

I was pretty sure this was the amp that didn't have a balance control. I remember how much grief that caused me when I really needed one. So, that's the one thing I didn't check. What if I'd remembered wrong? What if one of the kids moved the PC and bumped the balance knob? CRAPCRAPCRAPCRAPCRAP!!!!!!!! The balance knob was all the way to one side and when moved back to center, the Onkyo is fixed. When I had the Onkyo off the table, I'd replaced it with a Pioneer home theater unit. I am so glad to get rid of that one, it really sucked compared to the Onkyo. I am not really an audiophile - I can tell the difference between good and bad styluses, good and bad speakers, but never was able to tell much about the amplifier. But the Onkyo is head and shoulders above the Pioneer. |
