I've got a friend with a Samsung LN-T5271F flat panel LCD TV that has
trouble powering up. The red power light comes on then the blue light
comes on then the whole process starts over. This can go on for 15 to
30 minutes before the set actually starts up. Anyone seen this before
that can offer advice as to what I should look at in the power supply?

Sounds like power supply problems. We've seen many of these on similar
models.

Are you a technician and / or have you the requisite skills?

Yes I am a tech with many years experience, but have never
opened up one of these and currently have no access to
service docs. I had someone else say that it could be a bad
capacitor (very descriptive eh?). A lot of switching
supplies do fail due to bad caps. Discount-Merchants.com
have the supply board for this unit priced at $179.99 USD.
Unless there is something else I should look for, I may just
buy the power supply board and be done with it! I will look
for short circuits on any of the feeds from the PS to see if
that is a cause of the cycling.
