Hi all - glad to find this resource.
I know little about electronics but I'm a tinkerer. So when my LCD TV cut out on me I made it my mission to fix it myself.
It is a power supply issue, requiring the replacement of 3 blown capacitors and a shorted zener diode. However, I cannot [locally] find the correct diode value of 27v/1w.
Since they are cheap, I purchased both a 24v/1w and a 30v/1w zener. Through research, I've learned that I can safely change (raise) the voltage value of the capacitors I need to replace (from 16v to 25v) and may even wind up with a more reliable device when done.
Can the same be done with the zener diode? And if there is an allowable variance here, which diode should I use; the 24v or 30v?
Thanks for any and all advice!
