Re: Samsung LN46A550 Power Cycling

Thanks for the info on R106, did find out C107 & C139 are 10nf 50v.

Thanks again

Thanks for the update on the values may help someone else in the future.

Re: Samsung LN46A550 Power Cycling

??? It's two capacitors one resistor...

R106 at least is clearly a 2.7k, probably 0805 size. No idea what value C107 and C139 are.

sorry i was too late to edit (just re read that now what i wrote) im sure/hope the op got what i meant when i said the resitor had the marking on it.

Re: Samsung LN46A550 Power Cycling

Do you mean what they are as in two resitors and one capacitor or do you need the values the resistor has it wrote on it not sure what value the capacitors are though maybe in the schematic though.

Re: Samsung LN46A550 Power Cycling

maybe this one but does depend on what chassis the set uses does it say on the back panel sticker whats wrong with your tv are these parts burnt/missing?

I need to know the values of all three (3). Where can I get a schematic?

Re: Samsung LN46A550 Power Cycling

Picked it up @ U-Do-It Electronics, Needham, MA.....This place has everything and anything and if they don't they will order it for you!

Re: Samsung LN46A550 Power Cycling

Where can I pick up this MLC 30pF......?

Re: Samsung LN46A550 Power Cycling

I thought he wanted to know the value of C139?

Sorry my mistake.

Re: Samsung LN46A550 Power Cycling

I'm reading 30pF. That's in circuit,I'm afraid if I desolder it,I will never find it again,lol

Re: Samsung LN46A550 Power Cycling

I need to know the value of C139 then pick one up to repair

Re: Samsung LN46A550 Power Cycling

We need to see how the cap C101 is connected to the MP2363 circuit.
Is one end of the cap connected to pin 5?
It looks like it is also connected in parallel with the resistor next to it.

Re: Samsung LN46A550 Power Cycling

I got that board here,what do you want me to measure?

[budm]

Re: Samsung LN46A550 Power Cycling

So is this cap connected to FB Pin 5 of IC MP2363 and GND?

Re: Samsung LN46A550 Power Cycling

Someone else with same board will need to desolder and measure for you, unless you can find the schematic...

Re: Samsung LN46A550 Power Cycling

On my board this very small MCL? is gone, my mistake dropped solder on it when taking the solder off the C139 came off with it, what size is it, what do i get now I need one do not want to get the whole board for a stupid mistake.....how stupid do I feel![
