Question about RCA P46921 46" Rear Projection Television
I believe that's a PTK195 chassis. Yo can verify that with the small sticker on the back panel of the unit. If so, there are a number of things to test: C11637 (1uf/16v Smd) off pin 16 of U11600 R13147 surface mount off pin 50 of micro C11611 (10uf/16v) C11604 (3.3uf/50v) C11623 (4.7uf Or 10uf) Audio output IC U11901 (RCA p/n#235446) IC is located at the front left of the board as viewed from the rear of the unit. R14139 (241320) for change or open condition Q11900 SMD near output IC, RCA p/n#215495 and lastly Q11900 the mute transistor. If ANY of this has you scratching your head take it to the shop and take these notes with you... One or more of the above is your answer and none of it is all that expensive... You could save a bit of money by taking the unit into the shop yourself too. Good Luck! Bill
