Re: usp440m-42lp psu
OK--Thats one of the 5V lines--there's usually a few. Some will be powered, some not when in standby.
Check 'em all, post results and the names/references of 'em pref with a pic of the plug you measured them at...

Re: usp440m-42lp psu
Thing is--The V7 is pretty long in the tooth now, and only a 480p res, so not worth spending any real dosh on--certainly not investing say 50 quid in a PSU!
A few tests will determine whats what...
Firstly, with set unplugged, use your meter to check the fuses on Y-SUS and Z-SUS. Any blown and there's a short somewhere....
Then check the resistance from each fuse--to chassis metalwork. This should initially 'kick' or read for say half a second as the caps charge, then read a pretty high resistance.Last edited by Alastair E; 03-09-2014, 03:33 PM.Leave a comment:

Re: usp440m-42lp psu
Ha! A V7!
First plasma I ever potched with was a V7. Still got an alleged brand-new IPM for one kicking round somewhere....
10-1 that PSU is OK. You'll need to check for 5V stdby supply first before going any further.Leave a comment:

Re: usp440m-42lp psu
Fuse is good?
Early Bush plasma - probably early LG panel - 42V5/V6/V7? If so watch out for sparklies/maldischarge fault.
I'd check input fuse and bridge rectifier for DC.Leave a comment:

Re: usp440m-42lp psu
i have checked the voltage on the points marked in yellow, nothing at all no standby light nothing. i have done a minimal amount of checks as i was just going to replace psu. there is a big blue block (relay i think ) found a post somewhere saying it might be that, its a bush 42" PLASMA, i do not have model number as of yetAttached FilesLast edited by joehezzer; 03-09-2014, 05:46 AM.Leave a comment:

Re: usp440m-42lp psu
What tests have you done on it?
Stby 5v present?
Have you tried turning the PSU on by sending the PS-On, Vs-On, etc to it?
What set? PSU may well be fine--could be a Set fault and nothing to do with the PSU at all!Leave a comment:

Hi guys
I need one of these MP2329CGG for a repair job. It's a 24V 6.5A buck converter. But I have not been able to find a supplier who has that component.
Actually I would buy a few as I always think if I found one faulty already I will probably find more in the future
I had one supplier on Aliexpress who gave me a price $2 each, but I have been waiting some days since I asked for shipping price and they don't reply
Does anyone know where I can buy that part in small quantity (let's say 5 of them), or any equivalent I could use? it supplies the Standby... -

I've got a supposed blown transistor on my fuel pump on my car and I'm trying to replace it. It's a gel encased circuit booard with very fine connections. Please see photo uploaded.
I've cleaned up the area that I'm working on with alcohol scraped off the wires, etc..
I cannot get any solder to now stick any of the connections, I've used various grades of solder and flux combination, nothing... -
I have an ASUS ROG motherboard and it has a shorted/burnt component which I'm struggling to find or identify.
Any information would be greatly appreciated.
If anyone has the schematics/boardview that would really help.... -
Hello,
About a year ago, I was struggling to find schematics whenever I needed them. As a programmer, I saw an opportunity and wrote a few scripts to automatically gather a large database of them. Today, I've decided to share it with everyone, because good things should be accessible to all.
What's included? Over 14,000 laptop schematics, as well as some BIOS files, and about 1,000 phone schematics.
Everything is compressed in a RAR format and is over 140 GB. (Since it's such a large file, your browser might show a warning.)

Hi All,
Currently struggling with this bios and EC Problem and hope someone with more knowledge might be able to help, so my laptop PC Specialist Ionico 17 ( Tongfang GM7TGxP / 11800h rtx 3070 ) had lower than normal resistance on the PCH, so before i changed the pch i attempted to flash a bios/ec from same type of laptop board ( i am not the original owner and PC Specialist would not help ) which did flash ok but no change, after that i changed the chip and all resistance readings from all rails were normal, so i turned the laptop on with the new PCH and it turned on as soon as i...
