Suddenly my CLP600 power down and never power up. I pulled out SMPS and Check the voltage at each connector but no power read by multimeter.
I checked all components if there were burning mark by vidual but no burning mark. Is there any one who has same experience and please let me know where can I buy that SMPS?
I had the same issue. Samsung replaced two boards and the printer works again. The board that has the fuse is on page 2, box 11 (I think fuse is #10 in that box). I can't figure out where the 2nd replaced board is on this chart. I did not test the fuse, so I can't say if it was the problem or not. Hope this helps.

Circuit diagrams of SMPS section of many popular brand devices are given. Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
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.

switch off the tv & try to turn on after 10 min. if it happens again there may be loose connectors inside tv. if you can do: unplug the tv remove the back cover & have a close look for loose connectors.
As u mentioned about the click sound, the 5v standby supply is ok. The click sound you hear is from the standby relay. you have to check the other power supplies in the SMPS (switch mode power supply board) board. first of all check the standby supply 5v on tne pin of connector P800. check the voltage at this point in standby condition and at the time of power on. it should stay at 5v. if it reduces the you have to check the components related with standby SMPS transformer T501.
If the 5v volt is ok the u have to check the 3.4 v at the pin 1 and 2 of connector P802, at the time of power on. if it is missing then check the components related to T112 ,also check the following voltages at the same power on condition.
19v at Pin 1and 2 of P803 6v at the pin 5 and 6 of P802 12v at the pin 9and 10 of P802
check these to verify your tv's power supply proper care should be taken while working with power supply, because there is risk of getting electric shock. if you need any more assistance fell free to contact me through fixya. I have with me its field service manual ( does not have any schematics) if u need that i will sent it to you, if u give me your email id through fixya. ok
This is typical as the SMPS power supply is shorted when the connector is on to the board. when you remove the connector, the short releases and the power resumes as the SMPS has a high current cut off for protection.
So the easy way out is to have a multimeter and check the power line to the circuit disconnected to check out the shorted driver. Once you have zeroed in to the component release and connect power supply to confirm. Now replace the shorted component.
make sure that any high voltage in circuits are discharged when you use the ohmmeter in the circuit.
Make off power. Remove the RAM. Check the beepcode occurs or not. If beepcode is long then RAM DEFECTIVE. ===> Erase to polish contacts of RAM with soft white presto eraser. If beepcode not sound, open Processor and recheck. same. If again negative, just short green and black wire of SMPS after opening from motherboard. SMPS must start and check all voltages. If not start SMPS Defective.
Please give your feedback so that further repaire can be made.
In this case when it is always beeping during the computer is on. You need to check the memory stick if it is not faulty. Remove the memory stick and clean it from dust. Clean also the memory slot and reinsert the memory stick. If the problem still occur try to use the other memory slot.
did it quit making the noise when you lightly push down on the trunk? most people slam these trunks and your not suppose to you are only to put light pressure on them and they pull it closed theirself.. you might check your relays under the hood and look in the box lid to see which one it is.. if this is not the problem you might have to replace the motor to the latch .. you might check with a test light to see if there is power to the motor first though .. thanks and holler if you have more Jerry .
