Replacing Convergence IC's on Tosh 55h70

[Scuba Steve]

I was wondering if anyone knew if I could use STK392-180 Convergence chips on the Toshiba 55h70 or if needed to stick with the STK392-110?
I have read so much were the IC's were replaced and went bad not long afterwords, and wondered if the 180's would give me any more longevity?
Also, I didn't see a service manual in the database, did I miss it? if so, could someone point me in the right direction...
Thanks in advance for all the help

180's are fine to use. Don't forget to check R7731/7736/7726/7716/7721/7711
