installed is a Philips A66EAK220X01 VB9310 312,428th Does the
Rotschwäche (tending to dark red) to age or wear of the picture tube is
still what to save? For blue and green are available on the picture tube
trimmer Vb and Vg - I've changed as yet. Does it make sense to measure
the cathode voltage with a digital multimeter or should I rather use a
high impedance oscilloscope?

Hello.

My receiver Opticum 4050 CX gives me problems.

Top with the logo flickers.

If writing appears host, is also on flicker.

It also remains the progam (FIG) are kurtz.

What could be more?

THANKS in advance!

Such a flicker, I would rather want to blame the TV. Especially with HD equipment fits the zoomed image is not up to the grid.

This is probably more of a poorly aligned satellite system responsible.

Because some call the device names.

At the satellite receiver so you see no picture, but you probably still need a playback device.

Since your "flicker" but certainly also be related to the playback
device can, it would be interesting also tested by the types you know.

I am Metz TV angeschlossen.Wo he perceives new, there was (receiver)

which do not flicker.

Yesterday I had the SONY LOEWE u at u at the GRUNDIG,

tested.

It may well not be, it makes it to the TV, s is?

It brings so nothing, the mistake of describing some detail! If that's too hard to make a video or photo.

The logo alone, or the scripture can not blink, unless it is so
sent. The receiver has only reflect what he receives. What font or logo,
he does not know.

Fibrillation is a rapid change in brightness.

The whole sounds like to me still after a poorly aligned with
corresponding edges in the antenna in areas with a lot of movement or
sharp transitions (writing).

_________________

OK

I'm going to turn on the antenna.

To adjust the brightness, I am also.

Today I can not manage that.

Register again.

THANK YOU

This may lead to success in terrestrial antennas not sure the
satellite reception! To properly align the antenna you need an
appropriate measuring instrument, otherwise nothing.

There is still an easy way regarding Satempfangseinstellung ie be
followed by an analog Reciver and is receiving one as good as possible,
then you swap the analogue to digital Reciver and you have very good
picture and Emfpang. (this needs to buy is not necessarily a meter). MFG

The only thing missing to the time machine. The last program on Hotbird analogue was switched off for over 2 years ago.

Hi,

even if the unit is quite old, I would probably do it again take a
run and try it again to repair. I own this TV for a long time (over 20
years), it's a nice little device and I'm still as good service second
set. 've Thought many times to buy new land, but I am reluctant to throw
away a TV when he is not really broke, he just has a small error.

The problem which he has long, it takes very long to the AV channel
on a television program is displayed. It is powered by a satellite
system. It was not an issue as long as I had an analog Satreveicer. The
channel had broadcast the program on nem normal and I can watch TV via
the normal aerial socket. But now I've been around for some time, a
digital satellite receiver. I can only connect via the scart socket. If I
can now television set and satellite receiver turn on, then you need
the TV for several minutes until I watch the program. I fancy also that
it is somewhat temperature dependent. If it is cold in the room, dannn
he needs more time to run it. I then switched to the satellite receiver
off and on again and eventually it flickers briefly and it appears sound
and image (which speeds up the thing on and off)

As he said this mistake long ago and earlier it did not bother me
much. I have already spoken once many years ago with NEM television
technician who said it was no big deal, because a switch would just hang
and you could make if he was even properly broken .....

But since I only watch TV through the SCART input, but it annoys me
that I always have a good piece vorglühen a few minutes until something
happens [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]
I have looked at the matter even before long, I know that since
arriving on a pin of the Scart socket, a switching voltage, but I'm not
really come at the problem further. It would be nice if someone could
give me there are a few tips, what is wrong and how I could fix it
resolder (maybe even just what one would have to replace or low part
????)

_________________

Look at the scart socket and the ZF / sync block (in

available adjacent the tuner) times for cold solder joints.

As with the other modules too, often has the ZF / sync block

the solder joints on the socket connector cold solder joints.

(More info on. Switching voltage at terminals. Scartanschl of 8.)

To block resolder prefer, by a bolt from the

Solder side of her Chasisplatine be secured.

There may be buried in the form of cold solder joints of the dog in question.

Good luck.

Thank you [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة] But unfortunately not fit the schematics to my device.

Should it be this, then I had folegende YOUR fault causes in appearance.

ElkoC512, then the pulse capacitors CC516, C517 and C522.

The diode bridge EAST WEST D 505 was also a very common source of error.

Were cold solder on the diode or the capacitor?

_________________

'm assuming that this is the correct diagram now?!

When the D 505 was a "cold" solder joint, it has been damaged
according to experience and should be replaced. It could also be
defective R 536 and unfortunately, often the bridge coil winding
short-OW

Error: If after 12 hours off - Type: Elegance82MW82-150/8Dolby

Device Type: CRT TV

Defect: Come out after about 12 hours

Manufacturer: Grundig

Device Type: Elegance82 MW82-150/8Dolby

Measuring instruments: multimeter

Hello there.

After approximately 12 hours operating unit goes into standby just as if I press the remote control at the turn.

What's the problem?

Will no longer continue the internal TV Guide.

Is it because the latter is no longer transmitted with an error of the device software?

Otherwise unit is really top, only the two errors.

Thanks for the help. Unfortunately it did in the search found nothing.

The part has character.

Is there anyone who tortures his TV 12 hours straight?

About 1 hour a day that I could understand.

Whether there would be no help äztliche attached?

Sorry
