    Your problem this is Main

    Quote:
    IC DDR ram video memory DIP broken near ic scaler. It is typical problem on this MB.

    Read post (after registracion) on Link

    Most.very important is what is written on sticker /stamped the chassis /case tuner .. for example:
    on sticker BN91-00808 ( but on Main is written BN41- 00409C)

    Hi, unfortunately nothing changed, replaced ddr IC again and same situation, i measured on connector pin 27 det-5V is 0v it's normal ?
    If i buy new motherboard you think i resolve, and power supply it's not the cause?
    On connector all voltage are present and stable, only vblon and det-5v are 0v,
    for vblon i think it's normal because mainboard not complete the power on sequence, but for DET-5V i not know the function of this line.....

    Yes main board sub-micom doesn't complete power on sequence if DDR chip is bad It's like in laptop computers: Remove RAM memory from the bottom and the machine will get stuck in BIOS.... :D (by the way; how did you solder it? if it's BGA, you need to make sure all resistive balls are nicely soldered otherwise-still no boot-up trouble, or distorted picture effect will occur.

    Which DET do you mean? Panel lamp DET or AC DET?

    Hi, i not know was is the function of this line "pin 27 det-5V", probably Lamp Det.
    If if find another DDR Chip(last one i used its broken during desoldering) i do the last try before buy other Mainboard, thank you all.

    Please forgive my English.
    I have a samsung tv model LE32A336J1NXXC which does not turn flashing led red 2 times and Return to StandBy the power supply seems correct.
    might be failing as you say the IC 5201 K4D261638k or could be something else?
    thank you very much.
