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

Hello there.

If one of Works at home, so must be running and what is not always the case every day about 12 hours.

But your post helps me unfortunately no further to find the solution.

Hello,

I think you need a solution, at least when it comes to TV.

Hello there.

It would be very nice if serious contributions could lead to solving the problem.

Thank you.

Hello there.

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

Hi,

have for several weeks, increasing the same problem with almost the same TV Type:

- On TV, everything ok.

- TV suddenly goes off (red standby), is (occasionally) self again.

- Now is the distorted image (see attachments).

- Usually helps let off 1-6h, then he is (maybe) back to normal for 1-6h.

- Repeatedly off and on again (230 male drag) also helps sometimes.

Is this a secure (?) Sign of a cold solder joint?

PS. in which parts screwed TV I can not touch anything ... or about how long I must wait until the capacitors have discharged?

Best regards ... BrainStorm

That's not my device. But possibly soon? I will only go into standby, not more.

I just hope that someone helps us with serious contributions.

In another forum I found THIS:

Hello,

This is a Chasis Digi100 the series. The last of proprietary 100Hz Grundig chassis.

Ansich good chassis, but suffers in cold solder joints. Generally you view the chassis and resolder if necessary.

Sweden Points: Output line (spec. capacitors), Verikalendstufe, O / W - coil resolder absolutely!

In general, it helps to draw the feature board (caution is very
strict) and the feature module and the chassis itself ALL connections
resolder the plug carefully. Even if the solder joints look okay,
resoldering. If FUNZ again.

and here

Cold solder joint on the pin connector of the drive feature.

Again the question ... how long must I wait for the TV (when pulled the plug) before I can safely draw the internal connector?

enem in TV, there are mainly two capacities that can be recharged over time.

This is the picture tube (anode connection) and the Netzelko. At 95%
of the devices, the tube and if you wanted but discharged at the anode
connection do nothing happens anyway. The Netzelko could already make
more problems, but this is different for each device type. One would
measure only how long the tension still remains, therefore would be an
answer to your question is not easy.

Take a 50 ohm resistor and discharged him, then the problem would be
eliminated. Can measure even after that, even if Spg. exist, only if you have no idea about the matter, let the unit closed better.

No, I'm coming from electrical engineering (MSR), TV's, but the handling is limited mostly to the operation [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

P.S. All solder joints and resolder the error would be eliminated.

Yep, I will take next week in time attack.

50 ohm-R I would still have somewhere.

I wanted to give a short reply:

- Only time anything (connectors, PCB layout, etc.), photographed in the installed state (30 images)

- Dusted off because of all the health

- Removed the motherboard from the plug boards

- Accountable for the necessary cables Lötaktion

- Pulled out the motherboard, and in the vertical position at least
all the components described generously nachgelötet: capacitors, coils,
doubtful Safety Edge Lötpukte

- Put everything back together (no screw left or the board [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

- Switched on and ...

ALL AGAIN OK, no dropouts, no distortion, and (most importantly) stable operation.

Until next hiccups.

Very nice, at least one solved his problem.

But have received no reasonable answer to why TV will be easy to standby.

Can not imagine that it is due to cold solder joints.

Thanks for the help.

Repair: Tp Grundig

Error: Setting the Transmitter - Type: Tp661top

Device Type: CRT TV

Defect: Set channel

Manufacturer: Grundig

Device Type: Tp top 661

Hi there,

So I'll start like this: I have no idea comes to technology. I could not even fill in the fields above sry.

So my problem nr1 programs move where I want to go there hinhaben
it. 've All looked up, p / c i press the button and simultaneously do
not make me come to the menu. If I p / c push comes C. .. White had not
continue. Tuning and stuff I do not know how to do that ..

If I can answer that someone would be suuuper class.

My problem is that some stations for 2nd most eig very poor quality
may have something lying on the cable? If not how do I change this?

I thank you once already!

As I said I would not know anything about the technology but hinbekommen sooo glad I do not want to just buy new ..

Thanks and love greetings Anna

_________________

To 1: this would have to know what TV you have. TP661 is a remote control.

To 2: I can on cable, receiver, to the antenna, on television,
distribution, etc. are on the house. Virtually all sources of
interference between the studio and your own eye. To help you there, you
had to describe the problem accurately and clearly one would have to
know how you receive (Sat Digital / Analog, Cable TV Digital / Analog,
DVB-T).

Hey, thanks for your reply:)

So my tv is a Grundig Atlanta City is online!

Was just in the media market to me explain how I adjust the sender.
He explained to me that I enter for example a program then press the p /
c and then I manually alternate the space program for example one in
Würzburg cable 1 K05 .. 've Done this now but does not work well or can I
move it I think only the programs .. Now would just like to know the
quality will not improve my image as I set the remote control does not
have to search my sales or similar menu and I do not even ..

I would be pleased to answer and many thanks to ever ;-) lg

Oh I'm so all digital cable TV in the house bekom

s programs supernur nothing works for me: ((

Hi

If you have in your house only a digital cable connection, which I
do not think you can use the old machine to receive nothing because it
still guarantees no digital cable tuner (DVB-C) has!

However, it will be as the "all others" received a box of the cable
provider Adicional their digital TV and otherwise "only" the good old
analog TV programs in the TSO's tuner.

Exception: Newer LCD / plasma devices have often installed a DVB-C tuner.

Please try to find a guide on the internet if you can help niemalnd,
then it works too (assuming the TV is OK and you have connected it
properly).

That's what I found on the fast:

P / C = Programme / channel change

M = Save

->. = Search

N = standard settings

Good luck! [ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]

There was a sort or move it not possible for these old devices.

You can only save the channels to the appropriate places.

???

When a TV is analog and digital is not anything equivalent to cable
television. On the contrary, the last analog cable TV reception can be
when the analog Satausstrahlung next year will be terminated.

As for your picture quality, since you would have ever even describe
the problem. And often in complete sentences with punctuation.
