Question about Televison & Video
I'm repairing a Haier L30CV6-A1 LCD TV and I can't decide if the problem is with the Darfon inverter or the PSU?
The problem is the backlight lights for 1 second then turns off. Having checked the transformers their respective windings are about 900 ohms and all the CCFL tubes are working.
The PSU seems ok, no bulging capacitors etc. However, the 24v line is reading 25.3v whether the inverter board is connected or not. I wouldn't have thought this would be a problem!?
Anyone got any ideas please? Any help appreciated!
Hope everyone has a good Christmas :-)

Hi, Please measure all windings again and see if there is one lower than 900ohm. All CCFL might seem working but only for one second before the protection circuit cuts in. By the way, there is something that I would like to know, what is the type number of your remote control?
