SOURCE: LG 37LC7D Connect to VGA from a PC

Your right. I just had the same "Invalid Input" issue as well and it completely relates to the resolution compatability with any VGA or HDMI connection. Check the LG website for the online manual if you don't have it and see the section on RGB-PC cable. There is a table that incdicates the Resolutions the LG product is capable of displaying.

Thanks for the help.

Howard,
Do not keep forcing this unit on - - This particular unit has a VERY commonly known problem and there are at least five tech bulletins from LG explaining this and other symptoms for the failure. In a nutshell there are coils that have to be removed and replaced with a jumper wire. This is not a repair you want to tackle so please get some experienced help for this one. A good technician will look-up the bulletins and educate themselves on the manner of the repair.
Almost all of the symptoms that can happen are intermittent and can be extremely difficult to verify. For this reason make sure to discuss with the technician that he replace all of the coils listed in the bulletin not just the ones causing your particular problem. Here's a list of symptoms that these defective coils cause, taken right from the bulletin:
1. Channels Or Menu Functions Scroll On Their Own
2. Remote Does Not Function
3. Tv Randomly Powers On And Off On Its Own
4. Dead
5. No Backlight

Hope this helps!

I have a LG 37LC7D-UB tv. Trying to find part # 37LC7D-UB.AUSTLJM or Cap Kit for such. But when I find the part, say on EBay or other supply houses the board # is not the same. any tips on making sure

Ask eBay sellers to send you pictures and compare those to the original component, alternatively send eBay sellers pictures of your part and see if they can confirm they have the replacement for it.

If you want to change the caps, they should all be stamped with their ratings, you could order them individually from electronics suppliers. Just make sure you order the same ones in replacement, including ensuring the replacements are the same diameter. The last thing you want is to order a load of caps that don't fit around each other.

No sound on an lg 37lc7d tv?

Your main pcb could still have gotten damaged due to the defective caps. The reason you still have audio through the optical is because it is a digital signal only. It is not running through the audio amplifier on the main board. I would suspect either the main pcb or the speakers them self.
