Eh Dave, close the Fridge door before TEXAS freezes over. Thanks for the vid showing the blown FU-1 I would have thought that is was a transistor or diode, in that black package. Neat trick with the solder wick strand of wire for a tiny fuse. One of my FIX-IT projects - a Karaoke speaker/ amp with LED dazzle lights has me perplexed. Most of the system works, but only faint volume. It has an "effects / volume panel " which has no effect and a switch that seem to do nothing. I will break out the FLUKE and do some deeper investigation of the caps and unknown parts. Only issue is that the board is printed in " Ching-lish " I don't know what FU-1 would translate into MANDARIN . Keep it brisk and TOASTY up your way.
I'm glad you fixed it :) You were a bit more unlucky than I was. Your symptoms were slightly different. In my case, the display would function for a few seconds, then start shimmering and go out. Just changing the caps behind the level meters solved my problem, but in your case it popped the fuse as well. A nice satisfying repair. Excellent machines given they were the entry level Betacam recorders.
By entry level it doesn't have flying erase heads. This would have been primarily used as a player or spooler machines. They did make a playback only unit that was a little cheaper
@@12voltvids My 1600 does have flying erase heads, but can only be used in conjunction with a separate edit controller. I'm like yourself, I am primarily concerned with playback for archiving purposes. I think the 1400 was just a simple recorder/player and the 1200 was the player only.
@@richiereyn they all required an edit controller. There were a few different configurations. Player only, recorder, editor and top of the line features dynamic tracking so it will do variable speed playback like the Mitsubishi hsu82. So 10 heads 4 on individual piezo actuators to move the heads. As far as i am concerned though as long as it plays. Other then hauling it out every few months to make sure it work it will sit on a shelf till I need it for a transfer. I haven't had any BSP tape requests in awhile since i dumped my old BSP equipme when i bought the JVC gydv500. About 6 months ago i had a guy enquire about beta so he had over 100 tapes. That 1 transfer would have made me more than the old equipment ended up selling for. Now I can get those transfer orders because as i head towards retirement from the phone company I will ramp up the archive business so having all the formats i can get my hands on the better.
I had the power supply in the VU meter stuff a high voltage into the front panel electronics and blow all that up. So these VU meters should be checked out as a matter of course on these machines. I have another one in just today, with a mechanical fault I think.
Just tried to repair one of my cheap night lights (for kids). Everything I measured and desoldered and tried looked fine (like caps, PTC, diodes, zeners, microcontroller, LDR etc.). I gave up after about half an hour, just a cheapo Chinese night light, but - by accident - noticed that 2 of 3 of my new LED light bulbs (those small 1W stuff) were DOA. No wonder I didn't find anything broken.. *sigh*
You *may* have a problem with that board in the future. It looks like the trace between FU1 and C4 had some capacitor electrolyte seep under the masking and damage it, where it's all black. Looks to be going all the way to C5, probably where the electrolyte originated from. Maybe a bit more between R7 and ZD1. I prefer the twist and break method of removing those bad SMD caps, they usually just fall off, but there's something therapeutic about seeing them being cut to death and ripped off in pieces after all of the carnage they cause. I've replaced thousands of those stupid things, the damage they cause is crazy.
@@12voltvids It is indeed risky if you twist too far. I just do tiny 3-5 degree rotations back and forth until the legs snap, usually just takes a few seconds. I've lifted pads as well, but only on really bad boards where the electrolyte eroded the bond between the pad and the board, and any method was going to cause them to lift. Out of the thousands of caps I've done, probably only a dozen or so lifted pads with them. If the board smells like rotting fish, I know it's not going to be a fun time.
A volt meter measures volts and ohms. Some will measure amps and capacitors. Esr is a different type of measurement. Some high end meters may have it but most don't. That's why i built mine over 30 years ago. Paid for itself the first time i used it and rebuilt a switching power supply. I was a skeptic at first and after hearing that a few if the guys i knew in the business were using them i had to build one. It was only about 75.00 for the kit but to get the owner of the business to actually buy one was like pulling teeth. He wouldn't do it and i finally paid out of pocket for the kit.
Machine ate tape. It was the only one air machine as the backup was in shop. My boss said to do it and when the shit hit the fan he threw me under the bus and covered his own ass. Cleaning was operators job. Removing a jammed tape engineering job. Engineer said either i went or he did. 2 weeks after i was canned he retired.
Sounds like bureaucratic bs. I got in trouble at a former warehouse job because I would clean the rollers on the label printer if labels got stuck or started coming out faded instead of calling maintenance and being down for 20 minutes it would only take me a minute but it was not protocol. Never understood that. The whole idea was to keep production going and the alcohol wipes were right there so why wait for someone to come from the other side of the plant just to wipe a roller😅
Sanyo, Toshiba and NEC made betamax. Betacam was the broadcast format that the entire world used. Even though svhs and hi8 had higher lumanence resolution there is more to an image than lumanence and betacam checked all the boxes. Full color bandwidth and high signal to noise ratio. For analog tape it really looks nice. I have a digital betacam SX as well and for standard definition it looks fantastic.
It looks like that poor bird had a really bad day! Love watching your content! 👍😎
He flew it off
It's nice that you're happy that you have your UVW1400 recorder running again. Unfortunately I forgot to tell you that my fuse was blown too.

Electrolytic capacitors can sometimes short out and blow a fuse.wonderful!👍
Sure can. And blow other parts too.

Untill the twist and break method breaks the board. Has happened to me and that is why i don't do it.

Is it possible that you can use a multimeter instead of your meters that lots of people don’t have??? Thank you

What was wrong with taking the tape out if you needed to clean the heads? Why did they fire you?

@@JoshuaWilkesRthey also blacklisted me from working in broadcast which is what I went to school for.
@@12voltvidswow that is a dick move...
We used to have a Sanyo Betamax VCR. So Sony must have licensed Beta to at least one other company.
Betamax, yes. Betacam, no.

@@Shadepariah In Europe there was BTS and Thomson-branded Betacam SP equipment, of course made by Sony.
What happens if you carnt find the voltage of a bad zenor if there's no schematic. Is there anyway but not leaving it out. Thx
I probably would have guessed a value. Fortunately it wasn't cooked.
Thank you, keep up the good work x
Imagine the number of surface mount caps inside that machine that are dying as well. Those types of capacitor are a cancer for electronics.
Not many in this. Most are through hole
It's funny that the surface mounted caps had R1P printed on them. Looks like they all died and R1P ;)
In new zealand have 26 degrees celsous
