I think PWM is better because noise does not affect at all, what is important is the pulse width in the PWM PS type. Nevertheless if peak noise exceeds or increase signifincantly it is possible the switching transistor duplicate it and originate a damage, anyway if peak suppresor is used in...
Seems to be a defective circuit, if all voltages related to circuitry in Tcon board are ok, I think and insist that the problem is with the memories, Have you resold them with hot air pitol??...Possibly a defective solder could be ther reason, and other thing to check is the clok signal, I dont...
Hello there, have you tried to clean the connector from the Main board circuit to the LCD module (Slim type). Sometimes the dust can get into the contact and cause arcing or interference. Also you have to verify the memories voltage they are near to the processor. Regards...
Hello there!!..Can somebody helpe me, I am looking for a schematic for a DELL power supply ADP-150BB B 12V 12.5A, I am not able to see in the board the IC circuit number, it is scratched, I think it is not providing the swithcing signal to drivers. Thank you guys...
