When you turn on your set, it will blank / no message or hello on front panel, and it will not boot-up.

3-3. IC150 (No 1.5 V)

3-3-1.

Solution

Replace IC150 on main board.

3-3-2. How to troubleshoot (Countermeasure)

  1) Please check 1.5 V of IC150 on main board.
  2) If 1.5 V voltage doesn’t come out, check IC150 pin8(Vcc 13 VA).
    If there is no 13 V, please check 13 VA from SMPS. (go to previous page to check it)
  3) If Vcc input IC150, there are 13 V signal,
    First of all, check the PWR_CTL is high and if it’s high check C165, R165, L152, C169, R169, R170,
    R171, C174, C175, C176, C177 and if there’s no defective component, please replace IC150.
  4) After changing it, if the set is still not booting :
    - Check 1.1 / 1.2 / 3.3 V / 3.3 VA is normal. (please refer to other sections of this guide)
    - Check Crystal X501 refer to item 3-5.
    - Check NAND flash IC(IC603) refer to item 3-6.
    - Check DDR IC(IC601, IC602) refer to item 3-7.
    - Check MT8560 IC(IC501) refer to item 3-8.
