Hi,

Found up a piccy - seems to be a relay near mains input, not sure about any PFC - Chris

...Not familliar with this pcb at all ..
but the presence of a relay might suggest a seperate standby supply to drive the relay ..
Don't suppose that the small wound component is a mini mains transformer to provide the standby supply ?
A bit simplistic ...but might be a possible ...
If not then trace backwards from the relay coil ..and look how the supply to its drive transistor is generated ..

Hi,

On second look think I see a S/by TX and drive chip mid RHS - any secondary S/by 5V and red led ? - Chris.

not sure which chip you are refering to.

funnily I havent had one of these for a while but they were going down right left and centre at one point. Save yourself a lot of grief and get a new replacement from flee-bay for 30 odd quid. As much as I'm all for repairing panels sometimes financially its just not worth it.

Hi BB,

Its the black rectangular thing RHS just above that large copper-wound component - can't be more specific as have never met one - Chris

i have 5v at stand by but no led`s.

The most common fault on these would be the following symptom:

. 5v stand by, relay click, nothing. You also get a 33v near the connections at the top.

However as you've 0v across the smoothing block, you must have a primary fault, i'd check from the bridge onwards

Hi,
Wonder if the 5v S/by applied to the main board would help engage that relay to turn set on. No Red led points towards a main board prob - Chris
