opinions on rca xl-100

[Jeffhs]

My RCA XL-100 color TV (chassis CTC185A7) was purchased new in 1999. In that time (just under four years), I have had no problems whatsoever with the on-board tuner or the EEPROM programming (in fact, the picture and sound are excellent on Comcast digital cable with a cable box). My question is simply this: If the set has operated this well for this long, will the solder joints around the tuner still eventually crack? I would think that after four years with no tuner-related problems, the answer would be no. If I were to have problems with cracking solder joints around the tuner, however, when should I have expected them?
