Re[2]: JVC service or questions

I've got an 1998 AV-36980 that had the same problem. It was fine when I went to bed, but in the morning it wouldn't power on. I googled this type of tv and the problem which led me to this message board. I hoped that this was the problem. I pulled the circuit board out and C926 was bulging on both the bottom and top. I replaced it with one that I bought at Radio Shack for $1.70 and the TV turned on immediately. I'm 52 years old and have never messed with a circuit board, but this was an easy fix because of this message board. Thanks everyone.

    The orignal fix that I mentioned used a 35V capacitor - that was the OEM design. My TV went out again after about a year. I replaced the cap with two 50V caps in parallel (to get the same capacitance value as he original design) and have not had any trouble since then. If yours goes out again - beef up the voltage handling of the caps. seems there is an inrush of current that may be too high for this cap (a poor design)

      While there was probably no harm in putting two capacitors in parallel, this is not the same capacitance. It is double the capacitance. Using a 50V unit accomplishes your goal of increasing the service factor.
