  • Re: Samsung LE40R81B and clicking

    There is a link that caught my attention, [URL="http://www.ohmsupplies.co.uk/epages/62027733.sf/en_AU/?ObjectPath=/Shops/62027733/Products/SAM256SB4"]here[/URL], suggesting to change the eeprom after replacing caps if stuck in standby mode. I am not sure if I would consider it stuck in standby, since it is cycling. But I am wondering if this could be it..Re: Samsung LE40R81B and clicking

    But if the main board is bad, would I be able to force the TV on by holding the power button in for 15 seconds? As if the cycle it does to try to "warm up" the TV or what it does that for, is not enough. I just hold that little touch button on the TV in and then it eventually comes on as if nothing is wrong.

    I have now also tried replacing CB850 with a new one, but no luck. I am thinking of replacing the other 47uF 50V caps in the same area - not sure if any of them can be bad or if they have anything related to the symptoms with the click and blinking cycling. The ones I plan to change are CM851, CM854 and CM881 in addition to CB851 which is 10uF 50V.

    As you instructed, I have downloaded the manual (two different ones). And I did buy a multimeter the other day, but I am not very skilled at using it.

    On a different note,...

    Sorry for the picture quality, rather crappy. The last attachment (bilde1) should have been the first. In the upper right corner you can see the two blown caps. The third attachment is after I have changed the caps. The fifth is a closeup of where I did the soldering.

    This is what I changed from and to:
    CM853 and CM852: 2200uF 10v => 2200uF 16v
    CM876 and CM880: 1000uF 25v => 1000uF 35v

    CB850 is the one I tried replacing with a used cap, just to see.

    If the soldering job I did was poor,...

  • Samsung LE40R81B and clicking

    Hi,
    I know there are several posts on Samsung and bad caps, but I am a bit stuck now. My TV stopped powering on, just kept on flashing the red diode 5-6 times before clicking, then repeated flashing 3 times before a new clicking sound. So I opened it up and found two bad caps, one leaking a bit the other just bulging. As suspected, crappy caps from Samwha, 2200 uF. I ordered new [URL="https://www.elfaelektronikk.no/elfa3~no_no/elfa/init.do?item=67-042-97&toc=19089"]Rubycon caps[/URL] and at the same time got some 1000 uF as replacement for the ones that looked fine.
