LG video

[Martin]

Hi I own to dead LG videos Af293rw models,they both died a week apart same
problem no clock no power,when I did some testing I found the power supply
is putting out 5v and 20v DC .
I followed the rails and all seems fine ,no burn resistors or blown diodes
,so why cant I get them to fire??I cant seem to find any info on this
model,any help would be great?
Thanks Martin

Hi, take it to repair shop.
Schematics will not help.
If you are in Melbourne, call me (0414 635 468). Repair of this fault is
usually $55.
There are couple of reasons I am not telling you the cure.
1. Mains capacitor usualy stays charged and gives very nasty shock of 300V
2. While cure is similar between models, exact parts locations and values
are different. Without looking at yours, I can not be exact.

Hello Rudolf,
I do not understand your attitude here. I thought this was a group
where technically minded people with an interest in electronics
got together and discussed various topics.

I am sure Martin knows he can get a shock if he is sloppy
and not careful.

Rudolf, if you have a vague idea of what the problem might be,
give us the benefit of your wisdom, but then, maybe you are
touting for work.

The fact that Martin has two identical video machines and both
died a week apart is interesting. Maybe someone else can shed
some light on the problem.

C'mon Rudolf spit it out!

Regards,
John Crighton

Thanks for the reply ,I live in the country around 5 hours from melborne,$55
plus 20 to 30 freight compare to $140 for new one(target),just thought I
would have a play

**** Rudolph might be technically minded but the OP certainly isn't.
Rudolph made a very competitive offer to fix the equipment but the OP is
not the least bit interested,he would like to have a "play
around".Almost certainly,if Rudolph knows what is wrong with the machine
so too does the OPs local TV man.But the OP is too mean to take it there
,he wants elicit free information from this list and have a "play
around".

Technically minded people ,my arse!!!!!!!!

So you think this newsgroup should just be for repair men to find customers?

To all who replied to my original message

1. If I to give directions and someone gets electricuted -- I am
responsible. So, unless I am sure that person is a technician who knows
what
he/she does or I am sure that no risk is present, I will NOT give more
detailed directions.

2. If you read this newsgroup regularly, you may notice that I do help
quite
often.

3. I offered very cheap repair. I am 99.9% sure that no repair shop will
beat this.

4. Fault is electrolitic capacitor. It measures OK, but must be replaced.
As
I said, I have to take a look at the unit to see which one. There are lots
of them there! You do not want to go and replace them all. I beleive
problem
is caused by wrong power up sequency and CPU is not happy about it.

Now, what exactly did I do wrong in my original message?

Rudolf


Actually Rudolph, IMO you did nothing wrong. Contrary to what some have

said, people on this NG *do* help each other, including when newbies ask for
help. But when someone with absolutely *no* knowledge wants to repair their
kit, build a space shuttle, modify their crystal set to be an all-mode
scanner, or some such, a line gets drawn in the sand.

The OP got good advice.

Wrong if you spell out where the risks are.

So, unless I am sure that person is a technician who
knows what he/she does or I am sure that no risk is
present, I will NOT give more detailed directions.

But you are however very ready to ask for
technical details when you need them yourself.

And those who have provided them to you havent
been stupid enough to adopt your mindless approach.

2. If you read this newsgroup regularly,
you may notice that I do help quite often.

And much more often you basically tout for business.

3. I offered very cheap repair.

Pity that makes no sense in this particular situation where
the only thing that makes any sense is to buy a new one
or have a look at whether its practical to fix it himself.

I am 99.9% sure that no repair shop will beat this.

Irrelevant when even your charge makes no sense in his case.

4. Fault is electrolitic capacitor. It measures OK, but must be replaced.
As I said, I have to take a look at the unit to see which one.

Yes, its valid to say that that particular model has had too
much variation in manufacturing for it to be feasible for you
to list the possibilitys in a reasonable time, or that you
cant really remember the detail that well without actually
looking at a particular copy to refresh your memory on that.

There are lots of them there! You do not want to go and
replace them all. I beleive problem is caused by wrong
power up sequency and CPU is not happy about it.

Now, what exactly did I do wrong in my original message?

The waffle about electrocution when in fact the problem is that it
isnt easy for you to spell out which particular electro is the problem.

And in this latest attempt, not being able to grasp that
there will always be some situations where it isnt going
to be economic for the original poster to get you to fix it
and that in that situation it can be useful for him to spell out
roughly where to look if he doesnt care about his time etc.

Plenty of us are quite capable of avoiding
electrocuting ourselves and have been doing
that successfully since before you were even born.

You dont know that. You have absolutely no way of knowing
if he is sufficiently knowledgeable to avoid electrocution or not.

He cant be too stupid if he has managed to work out that it
makes a lot more sense to buy a new VCR than to get Rudy
to repair it for him and all he really needs is to be warned
about the risk of attempting to repair it himself, in case he
isnt aware that electrocution is possible.

Its never gunna make any sense with a technical group like
this to never give any info about situations where there is
some risk of electrocution if you dont know what you are doing.

Just as true of work on your car too.

I think you are taking that reasoning too far.
Lets just say, that you and I are having an argument.
I say, "Rudolf, go and boil your head."
Am I responsible for your injury or death if you do stick
your head in a pot of boiling water?

Yes you do, and very much appreciated.

3. I offered very cheap repair. I am 99.9% sure that no repair shop will

Dropped in on your bench at your work place you are correct but

with freight cost and messing around with packaging at both ends
the cost goes up quite a bit so Martin is prepared to mess about
and attempt a repair given a few clues.

You could have said that straight off.

Now, what exactly did I do wrong in my original message?

Having a "I know what the fault is but I am not telling you" attitude.

Reminds me of when I was a kid at primary school. A little girl
would come up to me in the play ground and tell me she was
not wearing nickers and then run off.

Rudolf


I understand the need for safety Rudolf, but on a technical

group where most of us are adults and like to play around with
electronic and electrical equipment we do so at our own risk.

I discovered the power of 240V when I was eight years old,
by unscrewing the two plastic halves of an in line switch
on a childs bedside lamp. I did not require a screw driver!
Both thumbs across the two wires gave me a chest thump I
have never forgotten. I did not tell my parents because I did
not want to loose the lamp.

I doubt that there are many kids reading what a bunch of old
farts are writing on this group who would then go off and risk
their lives with attempted appliances and TV set repair. They
have more exciting ways of risky living by killing themselves
with motor bikes, cars, alcohol and drugs. What I trying to say
Rudolf, is, lets not get too cautious with our electronic hobby.
Perhaps we can clear our conscience with any repair advice
by saying "Do these checks at your own risk" Just a thought.

I replaced 5 caps in the power supply and its working fine,one on the
primary 4 on the secodary side,I have over the last 20 years repaired all of
my electrical appliances including 80cm teac TV,I have a good scope,cap
meter,fluke meter and lot of test equipment,I did my basic electronic
certificate, and several courses over the past years and have a good basic
understanding,I just need a little help sometimes as I didnt have any
circuit diagram.

Thanks to all that helped

Martin
