No Display In Samsung Syncmaster 933SN Repaired
Received Samsung Monitor for repair stating problem monitor turn ON but nothing on screen-Blank screen.
For inspection I checked with working VGA cable but showing same problem. Now time to inspect it from inside.
Dismantled the unit & on first attempt I found degraded LCDS Cable.
So removed the cable & inspected circuit for any other type of damage. Removed circuit metal casing & found full of dust…. Cleaned the PCB using thinner.
Checked for any physical damage /burnt out but everything seems Ok. So now needs to arrange the LVDS Cable.
I arranged the LVDS cable from my salvaged material box.
Connected the Cable to panel & Logic board & Monitor is back to the life.

Wow... looks like all the coating came off that LVDS. Is that from years of heat (degradation)?

Waleed,
50% problems in LCD Monitors are screen related which can not be fixed & i salvage other parts.
