Sanyo DS27214 - Subbing the Power Supply?

Question

Does anyone have a schematic for this set, chassis 27214-00 ? The switching power supply is fried, someones kid spilled Koolaid or something inside it, and I'm thinking of attempting a last-ditch repair effort. I plan to sub the power supply with that from a completely different TV chassis, but in order to do that I need to know exact what supply voltages are needed. Bypassing a power supply with a different or even homemade one is beyond the patience of most techs, but personally I'd rather spend a few hours building something from scrap parts, than gamble money on OEM parts that might end up fried the instant power is applied. Thanks for any help

I managed to rig up a power supply - no thanks to you guys - but perhaps you can help me with one other thing. The set remains powered all the time - pressing Power only mutes the audio. Can anyone tell me how this set normally goes through its powerup sequence?

I do hope you never plan on giving or selling the tv set to anyone with the non-UL, non-approved homemade power supply.

It is one thing to rig up the set to verify that there are no other problems, another to do an unsafe repair and send it out to someone else.

What is the problem in properly repairing the switch mode power supply? They are not that hard to repair properly and be sure they are repaired 100%.
