There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

I have a LG 32LC2R The HDMI connection has been acting up a lot late to where I have to turn the TV on and off a few times before it set's it's self up. I watch Foxtel mainly.


call a tv repair shop and ask what it will cost for an estimate to repair . so do it free if you have them fix it .if cost is higher than a new set then you decide which way to go .

I have an lg 32lc2r flat screen suddenly picture went black but sound ok


That sound a lot like a backlight issue that in a lot of cases is due to poor capacitors on the power supply. The power supply also usually contains the high voltage generators that supply the backlight to the display. Search for that symptom on the internet with your model and brand in the search bar and you will find that a lot of people have the same problem. Those people that are technical often fix it by removing the supply and replacing the capacitors with those from DigiKey or Mouser Electronics. These new parts are not the very low grade Chinese parts that were made to a build the part. I have repaired many computer displays in the very same way- in fact the hardest part of the job is figuring out how to open it up. The capacitors I speak of are the larger Electrolytic types that are showing a puffed condition or are venting. See this answer as it has pictures.

HI, I HAVE SOUND BUT NO PICTURE


hi, if your tv has totally black screen the cause is either the inverter board get busted or the back light need replacement. if their is a white screen display but no picture, you must check the t-con board for screen panel display which have defective or burnt component parts .

HDMI, picture but no sound


Check the menus for both the DVD and TV to be sure that the audio is being sent thru the HDMI cable. Some sets and DVDs will separate the audio from the video be default unless told to send it down the HDMI. Update this if that does not resolve the problem and post the make and model of all gear in the chain.

Thanks,
Dan
