Re: Samsung LN46A550 Power Cycling

That is MLC capacitor, is it bad or something?
That is just noise bypass on FB Pin 5 of IC MP2363.

Re: Samsung LN46A550 Power Cycling

It is actually next c101

Yes, I did see in the picture (https://www.badcaps.net/forum/showth...t=47214&page=3) that you have marked and it is the bypass cap.
So the question remains, is it bad or what?
So you are not going to replace c102 for the common failure mode?

Re: Samsung LN46A550 Power Cycling

It's is next to C101

Re: Samsung LN46A550 Power Cycling

On my board it is gone, my mistake dropped solder on it when taking the solder off the C139 came off with it, now I need one do not want to get the whole board for a stupid mistake.....how stupid do I feel!

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![

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

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

Re: Samsung LN46A550 Power Cycling

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

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 thought he wanted to know the value of C139?

[buckscrape]

Re: Samsung LN46A550 Power Cycling

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

[martino]

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

Sorry my mistake.

Re: Samsung LN46A550 Power Cycling

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

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

Help me PLEASE.....! What are these items.....?

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.

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

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?
