Customer Question

LN52A530P1F Samsung tV black screen problem diagnosis
Submitted: 3 years ago.
Category: TV
Expert:  Frank the tv man replied 3 years ago.
IF YOU HIT TH E MENU BUTTON ON THE SAMSUNG REMOTE THAT CAME WITH THE TV DOES THE MENU COME UP? WHAT SOURCE ARE YOU USING? HAVE YOU TRIED MULTIPLE INPUTS?
Customer: replied 3 years ago.
Not menu comes up using the remote screen. As to inputs I've hooked the cabe direct to the TV... I can make out extremely faint (almost invisible) movement on screen
Expert:  Frank the tv man replied 3 years ago.
YOU HAVE A PROBELM WITH THE BACKLIGHT. MORE THAN LIKELY IT IS THE INVERTER. I HAVE SEEN THIS CAUSED DO TO A COLD SOLDER JOINT BUT YOU MAY HAVE TO REPLACE ONE OR BOTH INVERTERS. TO INSPECT THE INVERTER TAKE THE REAR COVER OFF. THE INVERTER ARE ON THE RIGHT AND LEFT SIDE UNDER THE BLACK COVERS. LOOK AROUND THE LITTLE TRANSFORMERS FOR A SOLDER JOINT THAT IS CRACK OR LOOSE. IF YOU DO NOT SEE ANY I WOULD REPLACE BOTH INVERTERS. I CAN SEND YOU A LINK TO THE PART BUT I NEED THE FULL MODEL CODE WITH THE VERSION OR THE SERIAL NUMBER. THEY ARE LOCATED ON THE RIGHT SIDE REAR OF THE TV.

Are you recommending I replace all four boards ? That's a bit spendy. Can Any further diagnostics be done to isolate the issue to one board or another?
Expert:  Frank the tv man replied 3 years ago.
YOU COULD INSTALL THEM ONE AT A TIME AND SEND THE ONES YOU DON'T NEED AS UNUSED.
