Re: Andersson TV + 17PW26-4 psu won't turn on?!
Thanks Guys,
Fuses on inverter ok.
I'll fix pictures in a couple of minutes and check things. What pin is ps_on?
And I did find a exactly similar problem which I'm having on YouTube, also with same PSU. Please give it a look. It is exactly similar situation for me.

I haven't replaced any of these caps because they all look ok, maybe I'll have to have a closer look.Re: Andersson TV + 17PW26-4 psu won'...

Re: Andersson TV + 17PW26-4 psu won't turn on?!
Thanks for quick answer selleoor,
No picture at all, no backlighting what so ever,
I'll try to fix a picture of the inverter board. However,
When I have inverter board and Tcon board both removed, I've still got the same problem, that said, the only components connected is PSU, motherboard, standby led, speakers and side control panel (touch)....

Re: Andersson TV + 17PW26-4 psu won't turn on?!
As written before, when trying to start the TV, I have 3.3v, 5v, 12v and 24v. When the TV goes automatically back to standby mode, that is, after about 10 seconds, all voltage disappears.
Or did I misunderstand what you meant reeceyburger123?

Re: Andersson TV + 17PW26-4 psu won't turn on?!
Tried disconnecting backlighting today - still got the same problem. Is it possible that the control panel on the tv could be the problem?
When I disconnect the control panel, the led lamp just keep blinking slowly and in the same slow speed. Is it possible to "jump" the control panel? Doesn't care If it works or not. Still got the remote and I just want the tv to work....Last edited by Eriksson; 11-05-2014, 03:53 PM.

T-con board.
Sorry about reposting, didn't manage to upload multiple pictures in one reply for some reason..
Did test the fuse on the T-con board, it was ok. Not sure how to test the "PFC voltage" though.
However, why I do suspect the PSU is because when I try to turn the tv on, it goes automatically back to standby mode after about 10 seconds. I do not hear any audio at all besides from the clicks when I'm pressing the control panel. Don't think any backlights work either.
I also discovered...Last edited by Eriksson; 11-02-2014, 01:31 PM.

Andersson TV + 17PW26-4 psu won't turn on?!
Hi guys..
Got an Andersson Tv 40" model A401FD.
So my problem is,
The TV won't turn on from standby and goes automatically back to standby after trying to turn it on. NOTICE that I got no picture what so ever. Only that the standby led disappears when I'm trying to turn it on.
The sound from the control panel on the tv works fine when I'm trying power/channel/volume buttons.
So I started doing some checks on the PSU
Can't find any caps damages.
The transistor/diod at the back side D879 is missing the middle pin?(3pins in total)...Last edited by Eriksson; 10-31-2014, 04:33 AM.
