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.

Sharp LC-32GA5U LCD TV . When the TV is on, the red spectrum color is lost resulting in a picture that looks mostly green. When the TV is first turned on it is fine, then shortly after, the normal color...

Hi well when this happens it maybe due to quite a few reasons unfortunately. It can be a bad PSU, a bad, color engine or indeed one of a myriad of things that can cause this. One simply MUST perform the troubleshooting steps to isolate and locate the fault. To do this, at least, one needs a service manual, accordingly please find the links above to download a copy if you want to DIY?
However imhpo, the very best thing you can do to effect a repair is to contact a local or head office from Sharp, and ask them for a referral to an authorised service center, now make contact here and either ask for a service call or take the unit in, in any event when face to face ONLY ask first for a "Quote" as to what's wrong and prospective costings and go from there.
imhpo In My Professional Humble Opinion.
