AC fuse, 4 amp, is blown and TV is dead. No other components burnt or
obviously faulty. It appears to be a power supply problem? Have test
equipment and out of date experience with electronic (tube) repairs.

Seeking advice; best place to obtain a circuit diagram?

Numbers: Model Sharp 14F24C and LL24146. Main circuit board number
K1530DE 0017.
Pix tube numbers, 370FCB22A and MIG244194

Many thanks Lauren

At the very least you should make a troubleshooting attempt at testing
the power supply diodes or bridge rectifier, the B+ filter caps and the
voltage regulator circuitry.... and always check the HOT and flyback
derived B+ lines..... report back with your component testing results
and voltage measurements.
You should also visit the website for this newsgroup at
http://www.repairfaq.org/
plan to spend some time there looking over the wealth of
troubleshooting tips, component testing proceedures, repair FAQS and
important SAFETY information. If after reading through the website you
are still not certain how to proceed then you would be best advised to
TAKE your television to a service shop for, at the very least, a repair
cost estimate so you can make an intelligent repair decision with facts
instead of internet wild guesses.

Check out the LOPT, H-Output, Vert Output, Etc. Repost the actual
diagnostics results you have done. As posted: Safety is mandated when
working on these things, from the old valve school, you should be able to
check this out with minimal aggravation.
