Re: LG 37LC7D black screen cycling

Upon cking all multi pin connectors prior to MM testing of voltages, one of two on the lower left side of PSU bd was loose and after re-seating several times for a solid connect I powered TV on and viola ! A fully operational LG .

I thank you guys for quik replies and pointed troubleshooting guidance.

thanks for the quik reply & link !
Will get a photo posted later this afternoon (pacific time USA).
I did consider that a bulging cap is not the only indicators of failure. As mentioned there are 2-3 that were not replaced since the kit did not include these, Id o have a multimeter to test voltages etc.
Will be updating later.
