The chassis number is PTV840. Capacitor 2442 (270uF) shorted in the 130 v supply. This caused coil 5415 (1.8uh) to burn. I replaced both the capacitor and coil as well as diode 6419. Because of flame damage I replaced diode 6417 and capacitor 2444. Fuse 1405 was blown and replaced. I then found that resistor 3415 (15 ohm) was open. I replaced it as well as IC 7411. Diode 6402 (BYV95C) is broke into 2 pieces. After replacing everything except diode 6402 the power LED now lights but there is no 130 v supply. Does anyone have any suggestions what to check next? Also I can't find diode BYV95C; will a 1N4937 work? Thanks in advance.

Thanks. I did do a search on ebay and only found the diode from Europe. Don't know why I didn't find the link you sent.

Sounds near enough to Europe to me, but the do ship Worldwide.
Nice of them to list "usa" in their seller name and currency in dollars. Very Happy

Item location: New Malden, Surrey, United Kingdom
