Re: Dead Vestel 17IPS71 power board

my guess its fith one down on the row you can get too.

Re: Dead Vestel 17IPS71 power board

ok yes I see the pins are on the side ...



do I need to put the black probe on ground?

Re: Dead Vestel 17IPS71 power board

ok great, where is the picture?

[vinceroger69]

Re: Dead Vestel 17IPS71 power board

basically cn4 and cn3 means two different connectors can be fitted to that pcb yours is classed as cn4 if you cant find pin 9 for now just test all the voltages i have added a picture so you maybe able too work out pin 9

Re: Dead Vestel 17IPS71 power board

the black connector (above) has CN4 & CN3 on the right (but no pin 9)

Re: Dead Vestel 17IPS71 power board

plug all leads back in and screw the psu back down turn your tv on put your multi meter on dc volts then put the black probe on one of the psu mounting screws then with the red probe test the voltages on that connector are they numbered? pin 9 is 5v stby there are two rows of pins on that connector so maybe easier to push the red probe down the side of each wire where it goes into the connector it should read voltages ok doing it that way.

Re: Dead Vestel 17IPS71 power board

you're probably much more capable than I am. can you also tell me which leads plug in and which to leave unplugged?

Re: Dead Vestel 17IPS71 power board

would this be safer? "could you measure the dc voltage on CN3-CN4 (black connector) with the mainboard disconnected and see if there is at least a standby voltage"? but not sure where to put the probes.

Sorry yes we all test things differently so i edited my last post im just going too look a schematic and will find test points.

Re: Dead Vestel 17IPS71 power board

put the power supply back into the tv you could then test the voltage on one of the connectors starting with 5v stanby .

Re: Dead Vestel 17IPS71 power board

ok thanks. fuse ok. I'd love to fix the board but my skills are limited. its probably best I replace it but are there some checks I can do to see if there is any output?

[vinceroger69]

Re: Dead Vestel 17IPS71 power board

yes thats the fuse you need to test so yes remove the board turn it over and measure resistance across the fuse it should roughly the reading you get when you short your multi meter leads together.

Re: Dead Vestel 17IPS71 power board

I have this problem and the same board.



Do I need to remove the board the test the fuse?

Re: Dead Vestel 17IPS71 power board

I am trying to fix a dead Vestel 17IPS71 and came across this thread (i`m impressed with the knowledge on here so thought i should register), i think i have the same problem as the op and i`m going to swap the ic.

My question is the only replacement i can source quickly is a FAN6300AMY, is this a suitable replacement?

Well if you need help with that Panny you know where to come. No issue is too hard for us

Re: Dead Vestel 17IPS71 power board

Have got another tv which I was given sat in the bedroom which has now been there since before christmas, may try and get that down next week and start playing with it
Its a 42 Panasonic plasma standby flashing and not powering up

Re: Dead Vestel 17IPS71 power board

I would like to try it in the tv and prove to myself it is working but as you said in one of your vids the lcd has no support at all when the back cover is removed, far too much flexing on the screen for my liking with the backremoved, would hate to damage the screen and waste all the work everyone has put into this to get it working

Re: Dead Vestel 17IPS71 power board

Thats great Will surely help others, and possibly me if I get one of these which will be soon. Not seen many IPS71's yet lol

Re: Dead Vestel 17IPS71 power board

No problem thanks again for the help
