I have this RCA proj. TV mod. P46734BA chassis CTC178, and I want to order an eeprom for it, but I am very confused over which part number I require. There are conflicting model and chassis numbers. On the actual TV chassis, the numbers are as follows. On stickers on rear panel, Model: P46734BA PTK-178LA Q 5456 K2N Serial no.: 602679034A On sticker on heat sink: CTC178L AB 5443 C6D >From a contact who has Parts Finder: Model: P46734BADX1= CTC178L Model: P46734BADX2= CTC178L2 Model: P46734BALX1= CTC178L Model: P46734BALX2= CTC178L2 Apparently, if I have a CTC178L chassis, I need eeprom kit # 212119 If I have a CTC178L2, I need eeprom # 237699 How am I supposed to know exactly what chassis I have? As indicated above, on the sticker on the rear panel, the model just shows P46734BA, with no other suffixes. Is the sticker on the heatsink the one to go by? Thanks for any help. -- Gary McCartney McCartney Electronics 7134 Fife Rd, RR 7 Guelph Ontario Canada N1H 6J4 Fax: (519)821-1530 email: number63@xxxxxxxxxxxxx ------------------------------------------ To REMOVE your email address, click here: http://www.tech-assist.org/unsubb.html ------------------------------------------ ***NEW*** Tips Added Instantly!!!*** Submit Repair Tips here: http://www.tech-assist.org/secure/tip/
