White screen with good audio. before buying pcbs & such. try my repair method.. you need to get the lcd unit off the facia & then remove the front lcd metal frame. at the top of the screen you have 2 thin pcbs - chances are that the ribbon cable got at least one track unbonded. first off put some double sided tape under the pcbs to stick then to the frame - that'll take the bend out of those pcbs !! next put cellotape over the ribbon cables. i then cut 6 pieces of sponge 15mm thick & wide as the ribbon cable & glue to the tape on the ribbon at what would be the top edge of the screen (covering the point where ribbon meets pcb).. put the metal frame on top edge first to keep the sponge straight !! put it back together & fire it up. if it still aint working you may need a tcon pcb (little square one at the top). this fixed my 42lg3000 but can work on others with same fault !!

Hi rossmc81,
If you can take it apart look for loose connection(cables) from the main board, t-con board, power supply. Pull-out all connectors then re-inset. If the symptom still persist, look for bad solder joints in said board. This symptom indicated of loose connection only...
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
No technician can do more than this, he/she can do anything except.

Lg lcd tv screen goes black but the sound still works 52lg70 screen goes blank, sound still works. i can change settings but cannot see the menu so the tv is still working there is just no picture.


This sounds like a mainboard problem. Unless you do not see a back light flash when you turn on the TV, which may mean it is an inverter board problem, this is most likely fixable by replacing the mainboard.
