LG 32LC55 LCD TV inverter problem

hi

the chassis is the LD73A and after 15 mins there's no backlight the audio stays on for a while, then the appliance switches to standby, searching around the web looks like the problem is the power supply board..does anybody know where exactly the problem can be and if it can be fixed without replacing power supply?

thanks

Hi jcost
Sounds like a fault I had on a similar LG model. Check out my post on 23. 04. 09. as it has info on an LG modification to cure tripping to standby. Thanks also to tv tony for the details. These smd inductors are on the main pcb near the power board connector and have screened connections to chassis making them fiddly to replace. Care must be taken to avoid damaging the print.
Regards
John.

hi Contrast john

i took a quick look on the topic you told me...and it seems the problem is not quite the same...

the power supply got replaced today but the problem persists...the TV works fine for 10 monutes
then it flickers and then theres no backlight and goes into stand by.

tv tony:
carry out the mods, the psu in these are very reliable, if you want details i will post them to you, tony walker

tv tony:
here they are
