[Xcat2008]

Hello guys.

I have purchased this TV not working... The owner of the Tv told me the TV had PSU inssue.. So, when i turn on the power cable, only show's the Blue Light from the Power.. When i press the P+ to turn on, that same light looks like week... So i supose it's the PSU..

Inside the TV the PSU have this reference: Beko Z1J194-11

I cant find to mutch PSU like this... The real question, this PSU it's the same?Looks like the same, look to one and another.

Thank you for the answer But i do not understand anything about this lol..

Just want to know if i replace the PSU with the Reference 06, will be the same as the 11.

Since this is only Power Supply, since the out put are the same, will work?


Regards.

Can you test the original power supply. Short pin1 & 2 of S901 and check you have the 24V & 12V outputs.

the blue light stays as it is when the remote is pressed?,sounds like you have 5vSTB but no PS-ON signal which is generated at the main board

I have no remote mate.. Purchased this TV whithoud remote... But i got the Buttons from the own TV..

Swtich the Power Supply and is the same as before with the OLD psu...

The Blue Light is always ON, the only thing i notice is, when i press the P+ Buttons or the V buttons the Blue light look like to Blink...

But no Image or light from the Tv

What can be now?

That's why it's always worth checking out the power supply before changing it. Can you check what voltage (DC) is on S901, pin1 when you switch on the set.

Re: Grundig 32 lxw 82-8600 - PSU Problem

There are a lot of voltage regulators on the main circuit board that need to be checked out. They supply,+5V, +3.3V, +2.5V, +1.8V and several other voltages.

Yeah that's true..

I will test the S901 in few minutes i cant right now. Thanks

But when i was testing few things, i notice this one got in the top pin 3.40V and in the down pin no energy... This is normal? Both pin's not should always have energy?



EDIT: That's only ilustrative image, the main Board is Z1J1 90R- 8

I am sorry Xcat2008 but I do not understand what you are trying to say?

Re: Grundig 32 lxw 82-8600 - PSU Problem

Ok.

So, when i power up the cable the S901 Got 0V, when i press the P+ Button to turn on then i got around 3.5v ~ 4V...

I supose the S901 Pin one, is the same as the S902 Pin 7. But i have test on Both, it's the same.

And for some reason.. when i was testing this ( Moving the PSU ), the white Lights from the TV start Blink and for few time got White but not totally white some part's red... Not stable... Now it's black again, no light's from the screen -.- Something is wrong..

EDIT: The 12V pin is the S902 Pin 6.

Re: Grundig 32 lxw 82-8600 - PSU Problem

Do you got a cable running from connector S304 (or S306) that goes to an invertor board. If you have what is the part number of the board and do you have a photo of it.

Re: Grundig 32 lxw 82-8600 - PSU Problem

I will check and take a photo for you. Need to take out few screws to get the Inverter Board. Give me few minutes.

Re: Grundig 32 lxw 82-8600 - PSU Problem

Can you check if there are any fuses on the board and check that they are not blown. Also can you check the voltages on S304. The picture shows where Pin1 is.

Re: Grundig 32 lxw 82-8600 - PSU Problem

Ok, no photo nothing now... When i took out the Invertor Board, one of the Light Bulbs came grabbed ..

Thanks for the help, now nothing to do. Tv for the trash.
