LG 47LC7DF Power surge (lightning) blew out hdmi and rgb and pc inputs, still have antenna and av inputs working. Is this an expensive fix?

The damage from a lightning strike tends to be random. Sometimes it's minor, and only a few parts are affected. Other times, many parts are ruined, or destined to fail soon as a result of the current surge.

If the strike came over the power line, the input surge protectors in the power supply should be replaced, even if they look good. It would be prudent to replace the entire power supply. If you had the set plugged into an external surge protector, that should have taken most of the hit and should also be replaced. (Some surge protector manufacturers will pay up to a certain amount for repair or replacement of equipment plugged into their products if it is damaged by lightning.)

If the lightning came over an unprotected input cable, fixing the set would be a gamble. You could end up changing a lot of modules, beginning with the main board.

Check the input or source on the TV to make sure it is on the correct input for the ipad.....

Its part of the main board in most cases

The HDMI switcher IC chips in TVs can be damaged but lighting hits near you house even if the power is protected with a surge protector. The damaging power comes in through the HDMI port and blows the chip out and it can affect just one port or multiple HDMI ports. Your best bet would be to just get a cheap HDMI switcher and use the one working port. The repair on the TV would require placing the control board and would run from $75-150 for parts plus the labor to install it.

If you mean the LG 60PC1D, it has 2 HDMI (HDCP) ports on the back of the TV. They should be just to the right of the Coax Antenna In connection on the lower left of the input panel. To the right of the HDMI ports are the VGA (PC RGB), PC audio in, and a RS-232 port. Crutchfield has the manual available as a PDF here: http://a248.e.akamai.net/pix.crutchfield.com/Manuals/689/68960PC1D.PDF . See page 9 of the manual for the normal rear panel input arrangement.

I hope this helps.

Any of these will work.

the dvi out of pc via adaptor to hdmi on tv has no audio,ok.
so LG diagram shows separate audio into Audio in RGB/DVI.
Resulting in video in on HDMI ok,but audio on RGB.Can not get both together.
Fix is revert to DVI to RGB lead with audio on RGB/DVI input.
The audio jack would only work with mono plug for audio in, to RGB.

This TV finds the connected input sources
automatically for AV1, AV2 and Component 1-
2. It is presumed that RGB and HDMI/DVI
sources are connected.

Check your setup to see if the audio is turn off but if you have a clear picture you should have sound.

Time to call a TV Tech if you are not going to repair the unit.
