SOURCE: PC smps power supply problem

ok you open the pcb check the fuse first then replace it if faulty if it burns again then check 4 diodes then see if 200v big capacitor is expanded or not if so then replace it if not then check diodes after transformer if short then replace it

SOURCE: Infocus projector power supply dead

the caps dry out. look for bulging caps. you won't find a schematic for the ps boards. infocus had someone else make them. the problem seems more like a overheating issue. as for the other one with the "just the fans", check the colorwheel.

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main 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. 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.

Player will not eject, play or stop, standby light will not come on


hi,
If there is no standby light then you have to check the power supply of your blue ray player. Its will be an smps power supply. Very carefull while dealing with such power supply beacuse there will be Live areas in the board. You have to check the fuse in the smps. If the fuse is faulty The its sure that the smps driver MOSFET is short. Before replacing the fuse you have to check the MOSFET. If not it will lead to further dameges to your system.
If the fuse is ok and the power supply is perfect then the mother board of your player is faulty. If so then you have to contact the nearest Authorise servicing center to get it repaired.
ok

I turned on the TV and it popped and went off and will not come back on


Hi.

When that happens you have usually blown the PSU. The power supply is the board connected to the power cord. If there had been a pop sound, power went off, and now TV is completely off, then the PSU has blown.

There is a 6 Amp 125 VAC fuse in the AC section of the PSU, that is the first part to check.After that test the PSU. Sometimes it is even possible to spot a blown capacitor in the PSU board. They look bulged, sometimes burnt and in some case you can even see a leak. Sometimes is instead possible to see a burnt area that is revealing a short, often in the AC section of the PSU. The PSU is located at the back of the TV. Power must be disconnected before removing back panel. Do not touch PSU. Capacitors can store and release heavy discharge even with power cord not connected. There are also 3 small brown fuses located next to the flyback. Those can be tested using a multimeter. Testing must be done by a trained person.

The PSU cannot be easily replaced with a new one. The part is not in stock anymore (part number was 264102), and it is not even easy to find on Ebay. The PSU must be repaired.

Regards.

Ive had this bluray player for 2 years and it was working fine, then one day i tried to turn it on and nothing happened. i checked if the fuse was blown but i appears to be fine. so there is no power...


hi,
there is possibility of two complaints.
1, The SMPS power supply fault
2. the mother board fault.
if the SMPS is faulty the you can rectify the problem. If it is with the mother board the you have to contact the manufacturer .
First of all you have to check the SMPS ( switch mode power supply). you have to check the voltages at it secondary stage. 5v, 12v, etc
switched-mode power supply (switching-mode power supply, SMPS, or simply switcher) is an electronic power supply that incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. Like other types of power supplies, an SMPS transfers power from a source like the electrical power grid to a load (e.g., a personal computer) while converting voltage and current characteristics. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage
for checkin the SMPS voltaes you need a multimeter. And check the voltages at it secondary stage
Added the inside view of BD 1600

if there is no outputs from the smps then you have to replace the SMPS drive STR ic near the big capacitor. Also ty to replace the OPTO coupler ic. y have to check the all resistors near the ic.

Remember one important thing that the capacitor can hold charge for some time even if you disconnect the power. so after removing the power. remove the SMPS very carefully. discharged the capacitor using a bulb.
i have also added a video for SMPS working for you reference will hep you for repairing your one

ok

Make sure the voltage settings are correctly chosen, or you have the correct power adapter.
