Let me start by saying hello
Now on to the problem.
I've been handed a Thomson 27LCDB03B that was reported as not always wanting to turn on. Anyway upon taking a look at it I've not been able to get it to power up at all, no power led, nothing.
Hunted high and low for a schematic and finally tracked one down and now I've done a little poking around.
I can confirm that I have 230VAC at PSU EMI board and a DC voltage of aprox 321Volts across the 100uF 450V caps, from there on the voltages appear to vanish. I don't appear to have a VCC voltage at pin 7 of U6301, nor do I appear to have any voltage present on the output stage of the transformer T6301 (pins 7 & 9).
I do have an electronics background just not in TV repairs so I was wondering if there is anyone on here who could work through this problem with me?
Thanks in advance.
