Having problems with your Flat Panel Televisions ?

Samsung PS-42Q96HD Hi My Samsung PS-42Q96HD went dead one day no pic and no sound- so I opened up the back and on the psu I replaced 2 bulging capacitors. Now the tv comes on with sound but with no picture. As far as I can tell there is power going through the X and Y boards and the logic board has 2 green led lights on. Any ideas would be greatly appreciated. Thanks in advance



Answers :

Please check whether the inverter is working and giving voltage to the display board. If not, this might require attention of a qualified service technician.

Samsung PN50B450B1DXZA will not power up. When I try to power it on, it makes a clicking sound and then nothing for 10-15 seconds and another clicking sound. The Red LED on the front flashes when it clicks but nothing ever appears on the screen. I removed the back of the TV and inspected Capacitors but do not see any that look to be bulging. When I try to power it on with the back off, I see a green light quickly flash on a logic board just below the power supply board. Are these clues helpful
