Like the title says looking for advice on where to start test for a short or other problems. Already made sure it is correct fuse replacement just looking on where to go from there!

Re: 40pfl4901f7 b Phillips t.v fuse blows instantly!
Check for shorted power diodes and FETS. Also google for a service manual.
You should also be able to measure the short from the fuse to gnd with your ohmmeter.Last edited by neilc6; 05-01-2020, 12:10 AM. -

Can you post a picture of the underside of the power supply.
There's a repair kit on ebay. Check the components shown with the components on your power supply.

Check the resistance across the Varistor SA601, if there is no short, check each of the 4 diodes D601~D604Comment
