You may want to check the listing for repairing the power board for your TV:
Make sure to read the failure syndroms as descrined in the repair service listing.
There may also be an article on how to check the power board with a meter - that is really useful and can save time and money when you can do it.

Right now only 5vdc standby power supply is working but not the rest, you need to inspect the 12v/24vdc power supply section to se if it has any bad component such as DC filter caps with domed tops.
Please read my guide and see the pictures in my albums to learn more on what to look for inside the TV.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Or www.digikey.com, just make sure to use caps with low ESR, 105c, high ripple current and long life rating such as PANASONIC FM or FC series.
Please post back what you find.
