Help with FSP212-3F01 low 24V and 12V!
Keith:
Hi,
Power the inverter from an external 24v supply and force it on to see if it is working.

Hi,
this is the schematic.

Sorry to say power supply schematic is for the FSP228 and not the FSP212. Though it may bear more resemblance to the right schematic for it than the one i have for it!
michael first:
Hi,
well maybe this one is right.
cheeky2:
Thanks for the schematic. I have used this together with the one attached to work out that ICS4 is the suspect that is faulty. They use about three different variations of this power supply in this TV.
ICS4 i think based on the cct diagram is a smd TL432 (SOT-23-3 package) which is a three-terminal adjustable shunt regulator
Does anyone know what the voltage should be between the pins? I anticipate trying to adjust the voltages by replacing RS39 1.13k resistor and putting a potentionmeter in its place temporarily (hopefullly this will determine whether the ICS4 is faulty).
I will give it a go tomorrow and will post results
