Question about Akai LCT2660 26 in. HD-Ready LCD Television
#LCT26Z4AD, No Picture & No sound. Red LED on. When power on, 5 second Green
LED on then 1 second off and 1 second on Green LED again then back to Red LED on.
So TV does not get picture and sound. I took it apart and there does not seem
to be any bulging caps on the power supply board or anything visibly burned. I
scanned solder joints on the boards and they looked ok for TV sets with no
visible cold or over heated ones. The voltages come up to full value when the
power green light is on and when the back light tries to light with 3 fast
striking/arcing sounds deep in the set the power supply will shut down. I assume back light is florescent and the
striking sound is a ballast of some kind. It sounds like a possible bad solder
joint on power supply or bad cap????
Any comments are appreciated.
If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.
