    Sanyo DP32746 capacitor help

    I am repairing a Sanyo DP32746 TV. However I am having some difficulty finding replacement capacitors.

    To give a brief synopsis of the problem, the TV will not turn on. There is not even a standby light when it is plugged into a known good outlet. Fuses are good. Power cord is in excellent shape with no shorts or opens detected. All solder joints are in good shape with no hairline fractures. I do not see any indication of burned or lifted traces. The one thing I did notice is one of the 200 volt caps is bulged at the top. The capacitor does NOT have a cover on top, plastic or otherwise. The top is scored with a "+" pattern for the vent and is metal.

    Also, please- I just want to find the replacement caps. There may or may not be another problem existing on the power supply board or even on another board altogether. The bottom line regardless of what the actual problem is is that I do not like caps with bulging metal tops.

    The original capacitors are Nichicon and are on the power supply board. The bulging capacitor is a 200 volt 820 uF GG series with a package dimension of 30mm dia. x 25mm tall. I would like to replace the 2 other capacitors, one being another 200 volt 820 uF and the 3rd being a 200 volt 470 uF with a package dimension of 25mm x 25mm series GN. They are all snap-in style capacitors that are then soldered onto the board.

    I am unable to locate either of the GG or GN series in the values I need. I found similar Nichicon capacitors with the right voltage and capacitance ratings and the same package dimensions but they are a different series. I was able to find the rated ripple on the Nichicon data sheet to make sure I am getting the same or higher but where I am stuck is trying to locate the ESR value on any of the Nichicon data sheets. Any help would be appreciated. Thanks.

    High voltage caps like these are usually general purpose so that's why you may not find ESR value mentioned in the data sheets. In such cases, just replace the original capacitors by capacitors that meet or exceed the ripple current rating value while keeping the voltage and the capacitance the same.

      Thanks for the reply. I'm one step closer to having this TV fixed. =)
