We have an LG tv 42PC3D when we turn the tv on it clicks on and off and does not turn on. We pulled the back off and the clicking sound was coming from a circuit board # 68719PT299A.


u have power problem. it is the mechanical relay clicking. it tries to turn on but since there is power related problem, it auto turns off again. it is the way they are desinged to prevent further damage. any LG service centre can replace the board or a qualified tech can repair.

LG 60PC1D making clicking sounds


Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.
Hope this helps
Please rate my reply ++++

Most likely a power supply component has aged and thus changed value and/or failed. Take it to a reputable repair person.

hi gsgoer
Just read the description of your problem and without being there with measuring tools;
The power supply estimate sounds like a fair evaluation of the problem in your model.
Good luck with the repair.

LG Plasma 42pc3d turns on, pops, turns off


Its very likely that you need to have LG perform a sodtware upgrade on your unit. Contact LG and see if your tv is one of the applicable units with software upgrade issues, please let me know if it works. Good Luck.

Screen has gone black


This thing's gotta go to the shop. Don't poke around back there, very high voltage. Check around for a reputable tv repair shop. If it's real heavy, maybe you can find someone who makes house calls?
