Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. 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 inverter board as card basis. http://electronicshelponline.blogspot.com/ To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.

Fault with 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.

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

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

Power supply light flashing.


Computer power supplys are modular replacement fixes. Better to replace the whole thing then try to repair.

No power


There is no reset on this TV. The SMPS (switch mode power supply) has been a problem on some of these models. There are no components available for this board as it has to be replaced as an entire assembly. If one or more of the fuses on the SMPS board have opened up then you might have a bad scan or sustain board. A qualified technician will be able to diagnose which board is loading the power supply if this is the case. Good luck to you. Joe Weibel customelectronics.org
