Philips 28" telly repair
 
My Dad's TV, a Philips 6315 (IIRC, 28" Widescreen), has packed up. I think
it's something to do with the degaussing circuit as the screen has
occasionally flashed up red when turning on, and the colours have drifted
whilst watching as if the deguasser isn't working properly. Turning the TV
on and off has sorted the problem, but now the TV won't turn on. The problem
is, we can't find anyone who'll repair a telly. Does anyone know one round
North Derbys / South Yorks / North Notts? Any ideas on whether it'll be
cheap or dear would be handy, as it could be new telly time if shops charge
a ridiculous amount to look the tv over.

When you say it won't turn on, do you mean video, or no sign of life at all?

When you say turning it on and off has cured the problem, you mean the
colour drift?

its nothing to do with degauss. You should find a repair shop that will
do a no fix no fee job. IME the smaller and more backstreet a repair
shop, the more chance of them getting it done within budget. Dont waste
time with the fancier premises.

How old is the set .I presume it is out of warranty but if it is ONLY just out
that might be very relevant

I'd also get a free or low charge estimate quote while you are at it.
This model, it's full number 28PW6315/05 (or similar) features the A10E
chassis with an expensive 'painter' £50 chip with hot air soldering
equipment required to replace it. An experienced TV Tech should be able
to tell you (due to the amount of sets he has worked through) if the
convergence faults and colour flashing is likely a phenomenon of this
chip failing - if so the repair could get costly :-(. But then again it
could be something pretty trivial like a toasted capacitor.

Unless things have changed, it's nearly always the power supply with
Philips TVs when they die completely. And they're so damn complicated you
often have to buy a repair kit containing all the ICs. This was the case
with my 28" 4:3 Matchline at only 5 years old. It would go to standby, but
no further. I checked all the caps in the PS with an ESR meter and they
were fine. The kit did the trick but cost 80 quid. Paying a pro to have it
sorted wouldn't have been worth it.

Doki has brought this to us :

The de-gauss circuit only works once, when you first power the set up.
It should not normally need to be used, except when the sets position
is changed.

Turning the TV on
and off has sorted the problem, but now the TV won't turn on. The problem is,
we can't find anyone who'll repair a telly. Does anyone know one round North

Probably because TV's are so cheap to purchase new, are so very
reliable these days and capable engineers plus parts are relatively
expensive. 'Won't turn on...' usually means a fault on the power
supply.

Consider buying a new one versus the likely cost of repair.

The trouble with modern smpsus is they check various things and wont
start if they dont get the right answers back. So smpsu faults are
somtimes down to the LOP stage. It stops fires but makes trouble
shooting more complex.

I know nothing of the details of your particular psu, but years ago I
tried replacing an smpsu with a light bulb... and yes, it worked ok. No
regulation of course, so the picture settings would vary a bit
according to picture brightness, but it was quite acceptable for a used
set. I doubt that kind of thing would be well received in the current
era of pixel perfect settings, but it is sometimes a way to make a
passable set out of a dead one. Parts cost about 20p.

In case youre wondering, I did it as much as a challenge as anything.

That's the model. It seems to have a very good picture and geometry compared
to more modern "better" flatscreen units, but if the bit's that much and is
that much of a pain to install, it might not be worth it.

They check the loading on each monitored rail is within specified
limits as they start up and if not shut straight down again. A
perfectly ordinary 100w mains lamp used to be adequate loading to load
test a TV SMPSU.

Slap it HARD with your hand, if this fails, trash it. Unless its worth
over 400 quid repairs are likely to be cost ineffective.

The message
from The Natural Philosopher contains these words:

Ah, the good old days of Percussive Maintenance are making a comeback.

They went away for a while, but not things are so cheap and densely made
that a good slapping is often the best approach.

Been there done that. The casing's too flimsy to make hitting it shake the

Doki,

There's a TV repair place in Thurcroft, run by my Uncles brother who
successfully repaired my parents dead Toshiba which I've been using for
the past few months.

Not sure of the name or address, apparently it's behind an estate
agents on the main road in Thurcroft. Send me an email to: ng at
joelwr dot plus dot com and I'll get the phone number and address for
you.
