[TechAssist] Re: Memorex TV (Tandy) Model SM2002RM, part number

Yes, that is a Zenith made TV with a main module  9-1151-01A.  The power 
supply IC should be a 223-28 or a STR53041.  If it is shorted then 
change Q3431 (121-1264-01A) and RX3433 (15 ohm),RX3434 (43 ohm 1 w) and 
RX3436 (10 ohm 1 w.). Also as a precaution C3432 and C3434.    John.
