The Bang and Olufsen 1001

A lovely B&O 1001 turntable from the early 70’s I was working on earlier, the beauty is in it’s simplicity, a motor, a very simple mechanism and a tonearm is all it needs to sound superb. And the brown envelope? It was inside the case and contained a wiring diagram, it had never been opened and it proves that companies like this expect their products to go on for decades, and at some point to be repaired.

This tangle of wires was what I found in someones loft, all I had gone there to do was to get one socket working and add a new socket in a downstairs room, all the other sockets in the house were working fine.This was a converted bungalow with a bedroom in the loftspace and just a crawl space ...

Workshop Day

I had quite a few repairs building up, most of them needing parts fitted, the first two this morning required some really delicate soldering, an AS-15 Gamma Correction chip on a Samsung t-con panel, around 1cm x 1cm with 48 pins, each one smaller than the tip of my soldering iron. This is an IC that can ...

Thursday 11/10/18

First call today was a nice drive up to Wheddon Cross, some channels missing and others breaking up. The main problem was that the tv’s were all tuned to the Welsh, this can cause problems as the tide rises and falls, mainly because the signal is coming in on the side of the aerial. A bit of a retune to Mendip sorted most of the problems out, except for one tv…all the mendip frequencies had good strength and ...

Tuesday 09/10/18

First job today was a problem with too much signal, yes it’s just as bad as not having enough! Obviously something common to the aerial because all three tv’s in the house were breaking up. Measuring the signal I could see plenty of strength but only around 50% quality, that usually tells me there’s something being over amplified, ...

Aiwa Direct Drive Turntable

I was brought this old turntable because it was cutting out on one channel, this was cured by replacing the phono leads, an easy enough job, but another fault was that it wasn’t lifting off at the end of the record. Being direct drive there are no mechanics under the platter to accomplish this so everything is done with electronics. To sense when the tonearm is at the end of the record there is a lamp and optical ...

LG Backlight Horror

A recent arrival at my workshop, the backlights were working but the picture had a lot of shading on the right hand side and bottom of the screen. It seemed there were a few LED’s out…as it happened there were only five of the eighteen LED’s actually working. On inspection one LED had burned up completely and the other twelve had probably died of shock at the same time. They were all short circuit and it was a ...

Bang and Olufsen Beocentre 2422

I bought this some months ago with a view to restoring it. I was relaxing in the south of France and just looking through some old hi-fi on eBay, this one caught my eye as it was not far from where I live in the uk and it was going very cheap. Supposedly fully working except for needing a cartridge. Normally that wouldn’t be much of a problem, but in the case of B&O only the original cartridge ...

Don’t bin it…get it repaired

Of course, I have a personal interest in seeing televisions and other electronic items getting repaired, but consider this:

We are constantly being told to save the planet and recycle, every week I seperate all my recyclable rubbish into paper and card, plastic and glass etc. and feel I’m doing my bit to cut down on the amount of ...

In The Sticks

It’s not everyday I get called on to travel so deep into the countryside, but recently I’ve had a couple of calls that took me up two of the roughest dirt tracks I’ve ever travelled (on four wheels). I’m not sure my poor van enjoyed it as much as I did though, perhaps a Land Rover would be ...

Mendip Retune 2018

It looks like Mendip is due for a major retune on March 31st, all frequencies will be moving on that date. I have no more information at the moment regarding time of day etc. At the moment it looks like the local relays (Porlock, Carhampton etc) are not going to be affected.

Please give me a ring if you’d like my help on or after that date

Thank you.

To repair or not to repair?

A very good question, and unfortunately the most common answer these days is not to repair. I’m not sure if that’s because people think tv’s can’t be repaired any more, or they think it will be too expensive, or they think there are no engineers left to carry out the repair. I understand also that a lot of people use the demise of their tv as an excuse to replace it with the latest all singing, all dancing smart tv.

Well ...

TX-L42B6B, No Start Up

image

I’ve had several of these now, refusing to come out of standby. At switch on it’s possible to see the screen light for a split second, sometimes doing this several times before going back to standby. You may need a darkened room to see this. The reason it does this is failure of some of the backlight LED’s, at switch on the ...

Beware of Yellow Pages!

I’ve said all this before, but I think it’s worth saying again, many people around here, and elsewhere no doubt, are being ripped off by companies claiming to be local, turning up from many miles away, installing the cheapest and nastiest aerial components and charging the earth for something that doesn’t work. I do my best to warn against these companies but by the time I’m called out to put it right the financial damage is done.

Some delicate soldering!

So I had a Panasonic Plasma in for repair, lot’s of short circuits on the Y-Sus panel. A pretty common fault on Plasmas, and not always a viable repair, but after checking the screen for damage, ie blown pixels / tiny cracks in the glass, I decided it was worth a gamble on the repair of the panel.

Not an easy job, the short circuit FET’s ( field effect transistors ) require a lot of heat for ...

Hitachi 42HXT12U

No Picture (LED failure)

Before going any further, this isn’t intended to be a tutorial for a DIY repair! I regularly get contacted by unqualified people asking my advice, usually when they realise they’re in above their head or have damaged the screen or the power supply. This is merely intended to show that this kind of repair is possible by a qualified engineer!

Depending on the make and model of TV, LED failure can present itself in a couple ...

Toshiba 40L1333B

This 40″ LED TV from Toshiba seems to be turning up in ever increasing numbers with no picture, either permanently or intermittently. If you talk to Toshiba they will probably confirm that you have a faulty screen, however, that’s as far as it will go, as far as they are concerned screens are not repairable items and the price of a new one would be far more than the price of a new TV.

The problem with ...

Cheap Aerials

Well I always bang on about these two things…1 – never get someone out of Yellow Pages because they sound cheap and local, and 2 – you get what you pay for, although if you go with option 1 you will definitely pay more than you expect.

I’ve seen the vans in the area, I won’t mention names but the vans advertise aerial installations for £39 + VAT, this raises one important question for me – what ...

Samsung PS42A457

A PS42A457 Plasma TV. Stuck in standby would be a better description and once again, the customer wasn’t really sure if it would be worth repairing. The standby light was on but there was none of the normal clicking from the power supply relays and no response to the remote or front controls.

Due to the lack of relay activity this was probably, but not certainly, a power supply problem. What the relays do is feed the ...

Poor Gecko!

Dead Gecko, Steve hill TV servicesWell you see all sorts in this trade but this was a first for me. I’m in touch with fellow engineers from around the world and this poor Gecko was found in the back of a TV in Albania. The TV was wall mounted and should have had a cover fitted where the stand slots in, ...

Humax PVR-9200t

Problems with Humax PVR'sI was called to this recorder because it was locking up, it would stick on one channel at switch on and not allow any channel change or menu operations until it had been switched off and back on at the mains, even then it would only operate for a few seconds until it locked up again. This is ...

Too much signal?

Is it possible to have too much signal from your aerial? What would the result be if this was the case?

The answer to the first question is yes, and to the second question…the result would be the same as having too little signal, a pixelated picture or even no signal.

Twice in the last week I’ve been called to homes where this was happening, both homes had aerials that had been fitted by me four ...

More Old Hi Fi

Ok, so I’m not sure Hi Fi is quite the word for a Sharp VZ-3510, it’s an all in one unit with an upright turntable, very cutting edge back in the eighties, but perhaps a bit gimmicky!

This one had been purchased from eBay and the radio worked, the cassette deck worked and the turntable door would open and close but it would not play the record. This took me back to a day where I had ...

Music Over Wi Fi

Here I will try and describe my own music system. Several years ago I decided I wanted rid of my sizeable CD collection as it was taking over one of our rooms. The solution I found was to rip every CD to a network attached storage device ( or NAS ). The one I chose was supplied by DBM Servers, viagra 60mg it was 3Tb and contained Vortexbox software and a CD drive. ...
