    My friend is doing that becouse I don't have equipment for measuring. He said that all caps are okay he told me he spend 5 hours getting them off, measure, and solder them again. I just gave him psu board without TV, I will check and inform today if TV turns On when I connect it all. I know it would be better that I gave him TV, but I don't have car for transportation so I didn't have much choice. I mean what's the worst it can happen TV will not turn On and that's it, we will investigate further. I believe he checked CM808 as every other capacitor, but I will ask him when I see him today.

    P.S
    Can someone answer me what I ask about my T220 monitor in previous post please, thanks.

      Most people only check the electrolytics caps not the film type cap, so you need to verify that for sure, and the 360Vdc is also important.

        Re: Samsung LE32R88BD/ BN44-00155A

        I just brought back PSU and connect it to TV, turn it On but still same with that CM810 and RM801 replaced with working ones and all glue removed.

        When I turn On TV red light just blink like it needs to be turned On but nothing, no backlight no picture and no sound. I manage to organise transport to my friend and will bring tv to my friends house for proper check and test.

        I will tell him what you said to check that 360Vdc between the two legs of the main filter cap when tv is turned On, what if it's not 360 or if it varies ?

        If it's one of those inverters is it worth changing and what kind of inverters go on that board I need some model or something or maybe it's best to order from ebay and change the whole board, I saw for 20-30$ used boards is it even worth investing 30$ into new inveter board for this tv ?

        And do you have any other suggestions what to check except that ?

          If you look at the schematic.
          That cap I told you to check is for the 24V, 13V, and 5.3V power supply section, if it is bad then you will not get those Voltages, that power supply section requires the boosted Voltage to work.
          "what if it's not 360 or if varies ?' It should be pretty steady. You need that boosted Voltage before going further.
          Have your friend look at the schematic.

            He said that he unsolder that CM808 and measure him and it was ok, but he didn't have TV with him to test everything else like that 360DVC on main cap filter, so I will go this week with my TV to him and we will investigate further. I really hope it's not inverters or something on inverter board (I don't have capacitors on inveter board just mosfets), and that some other capacitor is faulty becouse that won't be much of a deal to replace.

              Re: Samsung LE32R88BD/ BN44-00155A

              The bn44-00155A supplies the 24VDC to run the inverter board, so without working power supply you cannot tel if you do have problem in the inverter board or not.
              "(I don't have capacitors on inveter board just mosfets)" Are you sure? There should be lots of filter caps on the inverter board.

                Oh okay, good to know that.

                My bad, there are this low profile capacitors on the inveter board, and they all look fine no bulged on the top.

                here is picture of my inveter board

                  It would have been best to make the new thread in the beginning since your TV is not the same model as the OP, your TV is Samsung LE32S86BD, but it is too late now.
                  Can we get the pictures of the whole back side of the TV?

                    My bad I searched and found this post to have similar problem as mine, but I wasn't thinking about that I'm posting wrong so if moderators want I can make a new topic and start there.

                    Here is the whole back of tv, picture is not so great but If you want some specific detail I will photograph it.

                        Okay, if you have any more suggestions to add so I can tell my friend on thursday when I will bring TV to his place so we can check him out thoroughly.

                        I really don't want to throw away this TV it is 7 years old but I really like him, I don't think this is some kind of major problem I mean I assume it's not, and I don't want to give up on him that easily.

                            It is the biggest electrolytic cap on the power supply board with 450VDC rating on it. I hope your friend knows how to make measurement in the primary side circuit.

                              Yes that's capxon one 150uf 450V 105C, I think he knows I mean I don't know how much skill he have but I know it's not his first supply that he is fixing so I assume he knows.

                                Oh and I forgot to ask you what do you mean by "when TV is turned On" becouse I can't turn him On like I said I can just connect him with power supply, and press that power button so that red light can blink few times, is that when it needs to be measure when that light blinks or when he is just connected to power with steady red light ?

                                  I mean by hitting the power switch, so if the main board will try to send the command (PS-ON) signal to the power supply board and that is what we are looking for, if the PS-ON is present, then the PFC should come on. If PS-ON is not present then we know the problem will be on the main board.
                                  The standby power supply gives the power to the main board the minute you plug the TV into the outlet, the main board is then wait for the power on command from the power switch or from the remote to tell it to send the PS-ON to turn on the PFC and the main power supply section, the main board also then send the BL-ON and the DIM control signals to the inverter board to turn on the backlights, the main board also send the turn on signal to turn on the switched MOSFET to supply the Voltage to the T-CON board. There is a lot of action when that power switch is activated.

                                    We connect tv today and left him connected while we were searching something on the net and after 15-20min RM801 blow again. We unsolder him plus QM801 and QM802 and we measure them and they are both dead. Strange thing is that friend said when I brought him just supply first time without tv he measure them, and they were okay. So I bought two of 600V not 500V like default one is becouse they didn't have them but they said it won't be a problem. And now the real trouble is when friend was unsoldering that 22uf 1250V blue CM808 one feet broke, and now I'm having trouble getting new one, becouse in stores they only got 22uf 1600V but they are much bigger than default ones and this cheramic capacitor that is near him on board is problem becouse 1600V can't fit in. I'm searching now for 22uf 1250V but so far no luck, but I won't give up, it is only one that I need and we will solder them all again and test TV.

                                          Legs are too short and too wide they can't reach the holes, they made everything like that so you are forced to buy original one, and shipping to my country is 37$ ffs from ebay. So I'm searching for someone in US becouse shipping to US is 2$ and capacitor is 6$ that's 8$ total and very acceptable price comparing it to mine. Still didn't found anyone from US, but I'm searching like I searched my whole country for this capacitors, and in one store highest they have is 1000V DC and 600V AC with 22nF, and that one is too weak for what I need so guess ebay is only way now.

                                          His designation on the top says 22n J 1250V I google him and he is 1250V DC , 500V AC and 0.022uF. Thats the same thing becouse 22nF is 0.022uF.
