Question about Akai LCT2701TD Television
Hi! So glad to find this resource, as I'm having trouble with my LCD TV as described by another owner in this thread: http://www.fixya.com/support/t278524-lcd_television
My question is this: Can another diode be substituted for the 27v 1w zener described? I am having a problem sourcing that diode locally. Since you recommended the capacitors' voltage may be raised from 16v to 25v, I'm wondering if the same can be done with the diode. I purchased a 24v and a 30v (closest I could get to 27v) but have not yet heated up the soldering iron.....
Thanks for any advice you can give!
NO---- You can raise the wattage not the voltage. That component in whatever circuit it was designed to operate in requires 27v one direction thus a diode. At what strengths (wattage) will depend on the load. That particular diode will pass 27 volts up to 1 watt - one direction. Like a resistor never change the ohms rating but you can increase the watts, like from a 1.5 watt to a two watt or 1/2 watt to a 1 watt.
Unlike a capacitors that are designed to deliver voltage at a correct rate (ohms) its strength comes from its voltage rating. For a more reliable cap use a higher voltage but never change the rate.
