gthompson204@gmail.com: May 28 09:55AM -0700 I was recently given one of these, but it does not record, playback, rewind, or fast forward. I can still look through the viewfinder, zoom and focus, but nothing else. Any ideas on the problem(s)/solution(s)?

For whatever reason(s) the horizontal section is not generating the proper sweep waveform and since this section also provides high-voltage to the CRT (Picture Tube), the combined effect is evident on the screen. The high-pitched sound is coming from the vibrating core of the horizontal output (flyback) transformer. The flyback or horizontal output power transistor feeding the flyback could be bad or something else like a cold solder joint(s) might be the issue. Sincerely,   -- J. B.

Sincerely,   If that is like the trinitron that gave me trouble, YES check the Horizontal Sweep Section. The design there seems marginal, runs HOT, and appears to 'kill' the output transistor, but replace its driver too while you're in there. Why? 1. you're in there, and 2. When the output Transistor went, it takes the driver, or at least greatly weakens it. And, Why not rpelace it? What is saved by being cheap? PS: don't know if related, or cause, but one of the blocking caps was leaky and had to be replaced. I found out because the 'fix' of changing only output transistors lasted a few months before all wonky again.

If there is an electrolytic capacitor connected to the H drive circuit, replace it too.   --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com

A strong scent of ozone in the horizontal section might be an indication. Just another consideration in addition to those who previously provided timely troubleshooting tips. Sincerely,   -- J. B.

Phil   +1 -- Best Regards: Baron.         Many years ago I was working for a PA Hire company. One day we had a real "power surge". All the lights started getting really bright, then normal again, then back to really bright etc. It was quite a weird experience. I seem to recall we hit the emergency Power Off button in the warehouse after measuring the mains outlets being well above 300v.   Most of the office equipment got fried - photocopier, printer etc. but no humans or any of the audio gear were hurt.   We called in the electricity supply company, who (they said) discovered a bad Mains Intake Neutral connection. They paid compensation for all the fried gear, and we all saw the funny side.         Gareth.

"Ron D." <Ron.Dozier@gmail.com>: May 27 02:16PM -0700 I'll point you here: http://www.gryphon-inc.com/White_Papers.html   I've had extreme success with Powervar/ONEAC products. Like 25 years on a very critical computer system. The only failures were mechanical like fans and floppy drives. The hard drive was on 15 years before the system was upgraded. It did cost about $1K USD in the 80's for about 1000 W. Later, two other systems got the same technology.   Usually, the warranty and the sales receipt helps a lot. Less critical systems got the tripp-lite isobar which oneac doesn;t like either. I did see an ISOBAR fry and Trip-lite replaced the connected equipment.   I had an APC surge suppressor (given to me) and it's is supposed to be replaced because it causes fires. I think it's been close to 3 months now and no replacement APC. Furthermore, that APC did not protect itself. Oh maybe it did? It prevent itself from frying by blowing a thermal fuse and passing the surge to the equipment and lighting a LED.

An event that is so incredibly rare that the average person won't see one in several life-times.   The whole 'surge suppressor' industry is a con. It is the only significant profit area left for retailers of domestic electronic equipment. Profit margins run to several hundred percent. That said: A whole house suppressor is a reasonably economical solution to an almost non-existent problem. It must be fitted by a qualified electrical contractor.   FWIW: The only time I have ever heard of a significant surge on a power line, was at my previous home, before I moved in. A 5kV railway bearer fell across the 240VAC mains supply. This was in the early 1970s. It wiped out the electronic and electrical equipment for several blocks. I doubt that anything that can be purchased retail can protect against such a rare event.   -- Trevor Wilson www.rageaudio.com.au   --- This email has been checked for viruses by Avast antivirus software. http://www.avast.com

Some time after installing a whole house suppressor, we had an instance where power was going off and on during a storm. A loud crack downstairs, found suppressor blown. I replaced that one but have not found any other local supressor faulted that I know of. The model has a lower trip point voltage to other models I've seen. When I moved in this house the power company said a surge device was installed and if I wanted to pay monthly charge. I sad no, but never knew of anybody removing it from the meter, which would require power interruption. These things will not help a direct lightning hit.   Greg

I was checking a Sunbeam frying pan to see if it worked plugging it in in the garage when kbang. Tossed across the garage I went to see what was damaged, besides me.   Several outlets in the house had carbon scarring around them, the splitter to the color T.V. was mostly vaporized with just a small piece of circuit board with the ghostly outlines of parts no longer of the Earth.   The color T.V. worked only as black and white for some weeks when the color decided to return. Outside a bruise or three and a short case of the stunned shakes I was unhurt.   Not unusual around these parts to lose equipment due to surges coming in through the line, YMMV

As long as it's confined to the primary side of the power supply it's no big deal. Any fine damaged traces on the secondary means we go no further. My own TV (1991 RCA CTC169) got whacked when I was watching it. Blew everything from the SMPS primary back including circuit traces, and was left with two other issues (odd system control vol/mute function and loss of AV switching).

Since the newest generation now does HDMI switching in the main IC which is BGA, damage through the HDMI ports means a new main board. I recommend my customers to use the component inputs when using cable, sat, or IP TV. I haven't seen any damage yet via bluray player.

Notice that's it's under the CT Systems name, not Wavetek. Which does the front panel of yours say? <http://www.opweb.de/en/model.php?id=9197> I'll take a look this weekend.

Thanks, Lenny.   Jeff I think your 3000's must be the predecessors of the 3100. On my front panel in the upper left corner above the scope is a sticker (which is most likely covering up just the name Wavetek). The sticker reads "CT Systems". Then the original number 3100, that was printed on the front panel (which was not covered)is evident.   It must have been in the time that Wavetek became CT Systems. I guess that they didn't want to change the tooling for the front panel so they opted for the cheap way out. It's hard to believe that anyone would take over a large company with a prestigious name like Wavetek, and then simply mouse a piece of equipment like this. And then that they'd just keep on selling it as though it was a name change on a toaster. But hey, what do I know anyway?   I found this picture. It is of a 5100. According to the book that I have the 5100 was a later slightly improved version of the 3100. The specs may be slightly different however overall it's a very similar piece of equipment. Thanks for looking into this further.
