When you turn on your set, it will blank / no message or hello front panel, and it will
not boot-up.
3-5. IC201 (No 1.1V)
3-5-1.
Solution
Replace IC201 on main board.
3-5-2. How to troubleshoot (Countermeasure)
1) Please check 1.1 V of C272 on main board.
2) If 1.1 V voltage doesn’t come out,
- Check IC201 Pin 2 (VCC 12VA).
If there is no 12 V, please check 12 VA from SMPS. (go to previous page to check it)
3) If VCC input IC201 there are 12 VA signal,
First of all check the PWR_CTL is high and if it’s high, check R298, L201, C272, C273, C224, C225,
C209 and if there’s no defective component please replace IC201.
4) After changing it, if the set is still not booting:
- Check 1.2 V/ 3.3 V/ 3.3 VA is normal. (please refer to other sections of this guide)
- Check crystal X501 refer to item 3-6.
- Check NAND flash IC(IC603) refer to item 3-7.
- Check DDR IC(IC601 ~ IC602) refer to item 3-8.
- Check MT8550L IC(IC501) refer to item 3-9.
