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 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 ...

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 ...

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 ...

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 ...

Google Experts

Yes, I know Google can be very helpful for all sorts of things, I use it all the time for finding useless information, and believe me, when it comes to TV repairs most of the advice on there is just that…useless, written by people with no formal training or skills, or even regard for their own…and others, safety!

Most trades are regulated in some way, you can’t, or shouldn’t, even install a 13 amp socket or an ...

An old Philips

Well I say ‘old’ but these days anything over five years old seems to be considered ‘past it’. Well this seven or eight year old TV was brought into me completely dead, no standby light, nothing. This was expected to be terminal by its owner but was infact just a very small capacitor in the power supply. No, it wasn’t bulging as most of the youview and Google ‘experts’ would have you believe, actually in the last few ...

Paris

Well the first three days of this week were spent in Paris, leaving me just a couple of days to catch up on all the work. There were multiple messages left on the answerphone, as we expected, so Yvonne got cracking on those straight away. I find it unbelievable that people knew from the message that we would be back at work on Thursday but couldn’t actually wait that long, aerial work had gone elsewhere and a possible ...

Panasonic Recording Problems Solved?

Anyone that’s read my earlier posts may be aware of the problems with Panasonic DVD Recorders recording a favourites list rather than the selected timer program. This only happens with BBC channels and the theory is that it was an update the BBC had done to their red button / digital text service. Up to now nothing seemed to provide a cure for this but Panasonic have just made us aware that an over the air software update ...

More Hi Fi Repairs

I seem to be getting a lot of Hi Fi in for repair at the moment, I have a customer near Stogumber with a very nice Teac system and some time ago I was called to service the amplifier, this time it was the CD player that needed attention. Sometimes it would play and sometimes not, I thought it may be simply a case of cleaning the lens on the laser, this is very common, but in this ...

The Vintage Mitsubishi

I seem to have been looking at some really old gear recently, just shows how well built it was back then…the eighties in this case. But first, I had a mixed bag of jobs this morning…an aerial extension into two bedrooms, thankfully working indoors as outside it was blowing a gale and hailing. Then it was a simple job of connecting up a YouView box, then disabling a child lock at my next call, and then an even ...

The Vintage Pioneer

I had this morning free and really needed to get into the workshop to complete a few repairs, there was also a 37″ Samsung that had been dropped off at our house to look at, and a customer just around the corner with a 26″ Sony that was freezing on channel change, then rebooting itself. I had a nasty feeling this was another software problem associated with the BBC red button, the clue…it only happens on BBC channels! ...

The Samsung Saga

Well today was always going to be about the 50″ Samsung Plasma I’ve been working on for the last couple of weeks. Sound but no picture, doesn’t sound too bad does it, but on these it can get very complicated indeed. At the customers house I noticed that the top buffer IC had destroyed itself, this means the one below it is probably gone as well, also a whole host of parts on the Y-Sus panel. It’s a ...

More Red Button Problems!

Today started with a couple of aerial jobs, one inside and one outside in the terrible wind. The one in the loft was easy enough, just replace a two way masthead with a four way and run a lead into a bedroom, I was even able to use some existing trunking to hide the cable down the wall…an easy job.

Next it was out with the ladders and up on to a roof in Washford where the ...

A blast from the past!

Today started with something I haven’t done in a long time…putting a hairdryer into a video recorder! Why, you might ask…well I was called to install this machine not knowing that it had just been brought in from a cold car. Videos suffer badly from condensation and being brought into a warm room had caused a lot of it to form on the rotating heads. In this condition putting a cassette in results in the tape sticking to…and ...
