Re: No Power On Lexsor 32in (LC-32w18sd)
I've found a similar PSU board on line but it is slightly different from mine. Mine is KAS200-5S241812X VER A2.1 whereas the one I've found is KAS200-5S242212X VER A2.31. I was wondering would this new PSU work and is it worth buying?

Re: No Power On Lexsor 32in (LC-32w18sd)
Thank you both
I've checked the mains voltage on board and it seems fine and this also proves that rocker switch is functioning properly. I am thinking of removing the buck converter chip (5v 3A) and put external supply and see if it works, if it does then i will buy the chips and replace them both.Leave a comment:

Re: No Power On Lexsor 32in (LC-32w18sd)
no stand by light. Is that the 5v buck converter chip (on another board)? i measured the volts on that chip and there is nothing there but i thought that may be because there is no power going in from main PSU board.Leave a comment:

No Power On Lexsor 32in (LC-32w18sd)
Hi all,
I have a lexsor 32 lcd. It does not power up. I checked the input AC (240v) and also checked caps etc and they all seem fine. Measured the output on the PSU and it is all zero. Checked the buck converter IC's on the second board and they not giving any output either. Any ideas/suggestions please?
ThanksLast edited by ashok; 11-10-2013, 10:47 AM. -
Re: help with 32" LCD TV
just found them two IC's, i'll get the datasheet and check the output tomorrow. Should the output be 5V constant or doest it change? i.e. pwm, clock pulse etc?Leave a comment:

Hi Tom,
Do you know where the buck converter IC is located please and also do you know the chip number or the component number on the board please?
ThanksLeave a comment:
