Hi folks, I'm new here and desperate
I have been looking for information on the MLT668T-L1 rev.A power board that is in my 32 " LCD TV.
Anyone got the schematic? I need to know the value of a couple of resistor that blew up.
Help anyone?
thanks |

Are these resistors on the top or back of the board?
There doesn't appear to be much in regards to resistors in the TOP view of Shop Jimmy board, unless a heat sink is blocking my view.
The BACK view shows MANY surface mount resistors with well-labeled location numbers and can make out some part values.

They are on the back, smd. I can still see the part number on the board but not the value since it is on the resistors .
There's nothing on that link.

If you give part location numbers ... I'll see if I can make out.

Got it.
They appear to match the resistors shown at those locations on tanya schematic.
R64 / 60 / 58 / 55 / 53 |
