JVC Replacement Parts or Cross REF.

Okay, I am in the process of repairing my JVC AV-56WP84 Rear Projection Television. I found component Q522 shorted which is JVC part number

2SC5904-RL. JVC wants $45.57 for a new one. It has been quite some time since I repaired a television and I design electronic circuits for a living. Since when does it cost that much money for a transistor? So my questions are: 1. Where can I buy this component for a better price? 2. Is there a cross reference I can use? Here are some additional JVC part numbers I would like to cross:
  1. D932 JVC part number 31DF6N-FC5 JVC wants .06
  2. IC805 JVC part number STK394-220 JVC wants 48.94

Thanks for the help Kevin

How did the set fail? Convergence IC failure usually doesn't kill the horizontal output. Q522 is the output transistor, you MAY have a high voltage capacitor, or even the flyback MAY be bad, or just cold solder joints @ T 501 horizontal drive transformer. Also, check C 503 2.2 uf @ 50 volt cap in the drive stage. Does Q522 measure shorted out of circuit? Change IC

805, & IC804 in pairs, & don't use generic IC's. Check CP934 circuit protector ( ICP-N70-T), on the + 13.5 volt line. It's an IC PROTECTOR. 2.5A.

There are two versions of this T.V. AV-56WP84, or AV-56WP84HA ( HA would be at the end of the serial number). Look here:

Hope this hepls, Dani.

Hello Dani I purchased this TV from a private party as non-working. I was told that Q522 (2SC50804-RL) was shorded. When I took the set apart Q522 was missing. Currently when the set is turned on without this IC the front LED turns on as normal, the speakers make some noise for a moment and the screen is blank and all the CRT lamps are dark. So I believe I need to replace this IC before I spend additional time troubleshooting. I check most of the diodes (in circuit) with a meter and found D932 shorted which is JVC part number 31DF6N-FC5. So my plan for now is to order Q522, D932 (Do you have a cross for D932?), IC804, IC805 and all the parts you just recommended except T501. When these new parts are installed I will start troubleshooting again. I am hoping nothing is wrong with the lamps or Picture Tubes. I will also carefully check the solder joints and PCB around T501.
