[QUOTE="deltatango, post: 825904, member: 312296"] 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...... [/QUOTE]
