help needed

[Purity]

Hi again when the red bulb is not lit there is no power going to the board and now I've put a new fuse in not even the red bulb lights up only the yellow.one stays on thanks for being.so.patient with me i am really new to this thanks again for all your help i really appreciate it

Ok so that kind of confirms that you have a power issue?

Is the fuse exactly the same rating as the one you removed that was blown?

 

[kielmj20]

Yes sorry i matched the fuses. And now I've changed the fuse and nothing happened im scared that what ever was causing the problem has totally gone but i don't no how to trace the problem thanks for this again

Most things are fixable. Are you still getting power to the monitor?

 

[kielmj20]

Hi yes still getting.power to the monitor if there is any pic or anything else ya need. let me.no and ill get them asap thanks again

You need clearer pictures, the ones you've posted are too dark or blurry. Pictures around the power area, especially of that possible power board

Can you trace where the wires go from the transformer?

Obviously think safety. Don't do this with the power switched on

Do you know about monitor safety?

I think you still need to meter the power going into the board. The fact that the new fuse hasn't blown in no way proves that the power is ok.

For example, your power supply unit may be outputting 7 volts into the board. This wouldn't blow a fuse, but would knacker the board - hence coming on for a bit then going off...

Hi thanks for that ill take some.better pictures later and yes i do no about monitor safety ill make.sure.of.the power to the board and get back to you ill trace the wires to what i can and check what power is going to were and get back to everyone trying.to.help thanks guys really appreciate this

Just a quick one I've taken the little board out with the fuses on it and it says vg 001 on it and the fuse leads to a purple wire witch then goes to the multi plug and turned to two black wires if.it helps MORE TO.COME

 

[Purity]

Can you take a good picture of the board?

 

[kielmj20]

hope that helps

 

[Purity]

OK, so trace where all the wires go off that board, and let us know, where they all go

 

[kielmj20]

Right heare i go starting from the bottom ...... White and purple wire goes to transistor case ... Two Black wires .. One goes to a little black box ...one goes to a big blue like resistor ...... Grey wire goes to the power brick ......orange and white wire goes to power brick ......purple wire goes to power brick .......purple wire goes to the little black box ......red wire goes to the multi plug ........ Top six wires .......orange wire goes to multi plug ..... Red wire goes to transistor emitor ......red wire goes to multi plug ....... Purple wire goes to multi plug ......black wire goes to multi plug ..... Black wire goes to multi plug

 

[kielmj20]

Picturs are of: the board itself : the big blue resistor : the transistor and the little black box underneath : and the power brick .......... sorry i don't no all of the proper names of the parts im still learning. let me no if anyone needs any more pictures hope it all helps fingers crossed

What's that those wires are connected to on the bottom pic? Is that rust on the connectors?

 

[kielmj20]

The machine has been in storage and i guess the last person has soldered the wires straight to the connections i couldn't even tell you what those wires are there ain't no stickers or indication of what they do.. the top line has a purple . white . grey . orange and white ..... the bottom line has . green . brown and black

 

[phillv85]

Are the connectors from the wires to the unit on that last picture rusty? If so that could explain a power issue. I can't tell from the picture.
