hello: when you give power you have in the C821 and C822 the 135v of the + b ... they arrive at pin3 of the fli-bak ... it has optocoupler or not ... q, you have a micro jungle ... there are several versions of ptfmo2. ..
hello buddy: where did you take that voltage ... look or measure on C821 and 822 that's the volatje of + b ... and I should be at 135v ... and if that voltage you took it at C821 or + b .. .this very past voltage ... you can have prob, in the primary of the source since q, you say q, has no optocoupler ..ok ..
change the C811 of 220mfx25x ... also change the C810 of 10mfx50v and the C815 of 4.7mfx25v ... to make a measurement of the source voltage raise a leg of the L822 and the R821 q, go to fli, bak .. and charge the + b with a 60w lamp between the positive of the C821 and mass ... and you see what tension you have in C821 ...
Hello colleague: I followed his recommendations to the letter and dragged jewel with 135v, but the saddest thing is that I put the cable and I have no image, look for the channels when pressing any tur, measured the sinto and I have the 33v and other tensions check The tur because they could be resentful but it is not like I enter the menu and do anything, I suspect the memory, you can give me your opinion, I do not have the remote, thank you.
Before changing the memory, look at the ABL pin 8 of the fli-bak and check the R481 of 68kohm if it is not open ... it is connected between the + by the R482 q, go to pin 8 of the fli-bak ... this line from the abl it arrives until pin 14 of the la7685j ... it measures in pin 14 deven haver 6.2v ... given that, if you have osd there can be some prob, in the line of the ABL ... measure that, tension you have in pin 8 delfli-bak ...
