Looking for schematic for power supply Samsung PD46A1_CSM

Question edited for clarity to Add Samsung Television.
Question moved from computers and Internet.

Shop Jimmy will sell you a new one. There are some testing videos and if you click the images tab and replace the word 'testing' for 'schematic', there are BN44 schematics. The 932 seems rare.

tis a process so here goes..... Central Security Module (CSM) enable/disable mode allows autolock feature to be turned on or off. To enter enable/disable mode, close all doors. Ensure ignition switch is in LOCK position. Perform the following steps within 30 seconds:

Turn ignition switch from LOCK to RUN position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from RUN to OFF position.
Press power door lock switch UNLOCK button 3 times.
Turn ignition switch from LOCK to RUN position.

CSM module should chirp horn indicating CSM module is in enable/disable mode and ready to accept program changes.

Press power door lock switch UNLOCK button once to command CSM module to toggle autolock feature on or off. Press power door lock switch LOCK button once to enable/disable autolock feature. CSM module will chirp one time to indicate autolock has been disabled.

CSM module will chirp once, followed by a longer chirp to indicate autolock feature has been enabled. Press power door lock switch UNLOCK button once, then turn ignition switch to OFF position to exit enable/disable mode. CSM module should chirp once to verify a feature change. Best to you.

Fault in the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.
There are circuit diagrams [schematics] to some model power supply boards to Samsung. BN***** Series SMPS. Check it, and try to repair if you're sound in electronics, and has previous work experience in repairing the SMPS power supplies.

I just replaced my GX280 power supply (mini-tower) with the following 400W for $30.

The only place I can think you will find an actual schematic for the PSU is from the manufacturer.

Hello,

The schematic diagram is going to be very hard to get. We do repairs on this model. What information do you need? The most common problem is the capacitors on the power board.

CHECK ALL JUMPER ON THE BOARD AND MAKE SURE THE BOIS RESET JUMPER IS ON JUMPER 1-2, SOUND LIKE A POWER SUPPLY PROBLEM NOT ENOUGH WATT TO RUN THE SYSTEM

2ND OPTION, REMOVE ALL WIRE AND ADDTIONAL CARDS, MIN. MEMORY, LEAVING 1 STICK OF RAM, VEDOI CONNECTION , AND THE POWER TO THE BOARD, CONNECT ONE WIRE AT A TIME AND RESTARTING THE MACHINE EVERY TIME UNTIL YOU FIND THE PROBLEM.

I have the same issue.
I'm looking for the power supply schematic.
Some components are dead (like U501 and ZD501).
I'm looking for the reference of the zener. Does any body have the schematic or the part list of the board (ref PSPF501B01A) ?

you can get the power supply and/or the service manual (with schematics included) here.
