At the moment got an old a Metronic Dualis box working + 1Metre dish, moveable within 20 degrees. Got Astra 19deg sorted need to swing onto 28deg, also must learn French to read its instruction book!

Got a Philips 32PF5521D/10 TV with lack of picture at switch on sound OK, this occurs at random I have its main service manual for LC4.3E AB and the similar AA version but they fail to show its power supply.

This is a PLCD 190 P1 board number 3122 133 32806 can anyone help to supply a circuit etc.

I have found snippets regarding this issue relating to power supply or inverters (which also are not shown) in its manual, capacitors as I well know lead the fault league table so far I have found its main primary mains cap is low 107uF compared to 120uF and could well be the issue but would like to see the circuit to get a general over view of it.

Many thanks for any help......

The link here for the LC4.31E.AA schematic has the power supply included - is it the same board as you have?
