Re: Worth saving ? analyze this psu for me please
Try changing the output capacitors with some that have a bit higher esr - say 0.05 ohm instead of the fullcraps' 0.02.
It should not be getting up to 100C, that is too hot. I kinda suspect the capacitors have too low an esr xDMuh-soggy-kneeComment

Hi
I have a Samsung QE55Q65B with a seemingly common problem: it turn off and back on after a few seconds, (sometimes more, and in rare instances works for hours). D001 on the left side of the panel is very hot. I may be able to remove it with a very fine iron, but i don't have the equipment to re-solder such small parts.
Is there a risk to run the tv without this diodes diodes? And is it worth to pay someone else to replace it. I read many people who ended up with bad lines after trying to remove/replace them, , or the panel failing in another way, so i want to weight... -
Hi All
I have a KOGAN 58' LCD Panel that 'flickers / pulsates' when in energy saving mode.
I've reset the unit to factory default & rerun the initial setup but no change.
IF I choose any other mode, example: Standard, flickering disappears.
I've downloaded the most recent FW for this model from Kogan's website & re-flashed. This initiated a full wipe of the unit, which subsequently led to the setup all over again, however, the issue still remained - screen flickering but only when in 'energy saving' mode.
I've taken the unit apart,... -

Is this oscilloscope sufficient to analyze all points on a laptop motherboard? PWM of IC and mosfets for example, or detect communication between super IO for example?

I will be pulling my crown vic ECU and recapping it. 3 in total, 47uf 16v x2 and a 10uf 63v
I hope they havent puked yet. I was thinking of replacing them with Aluminum - Polymer thru hole caps. probably 47uf 25v and 10uf 80v
They arent cheap. Anyone have any experience with them? Am I wasing my money on premium caps?
Nichicon PLV series
thanks
