Forward voltage is almost double of the Schottky one. I'm going to order a bunch of SR515 from digikey but I'll have to sneak it into someone else's order to avoid the ridiculous $25 delivery feeRe: Hkl-480201b hkl-500201b hkl-5502... Schottky one.

Do you think replacing them with completely over-speced diodes is a problem?...

Hello and a happy new year!
I've got the same "TV dead" problem, so I pulled out D10 and D11. Only one of them was dead (don't remember which one) but I replaced them both. I couldn't find the 5A/150V diode at my local shop so I put two 6A/1000V "Fast rectifier" diodes in.
Tv worked for 2 minutes and then turned off. D10 is dead again.

Instead of trying to find a matching diode, I'm going to assume the problem is somewhere else upstream. Any thoughts how to find the actual cause?...
