Question about Sylvania LC320SS8 32 in. LCD Television
Need voltage rating of this zener diode. I think its either 3.9 or 39 volt half watt.
SOURCE: tv does not power up
You answered on your own. (lol)If its suppose to be a standby 12 volt supply then whats the top voltage to be there?? 12 VOLTS!!! The value your looking for is a 12 to 13 volts 1 watt zener diode.. Im thinking your a handi man trying or attemting a repair?? please remember the HI voltage saftey issues, as these sets hold alot of HI voltage even after they are unplugged for a while. Good luck

many of the dish remotes have a "scan" option. This is what the installers use. You'll ned to read the manual. Its a one page explanation.

Your tv dosn't have a digital tuner, in order to recieve OTA (over the air) digital signals you will need a Digital Converter Box.
Here is a link to a government website for coupons for the box. The coupons are for $40 off the purchase price of the box. There is a waiting list but they will come available as other coupons expire.
here is another site for antenna and channel line up.
I hope this helps and please rate this solution, please keep in mind that a "Thanks For Trying" rating is negative.

On the cathode of the zener diode look for a filter cap and check its value the voltage of the zener should be less than the working voltage of the zener. Basicly its likely being used as a shunt regulator as protection and regulation of the voltage. When the zener hits a certain threshold it will breakdown and start conducting to ground until the supply regulates and then it will recover. If the filter cap for that voltage rail was 25V I would guess that the zener would probably be regulating between 12 and 20 volts. I'd pick a 15V Zener its probably +- %10 on the original and any system should be able to take a %10 tolerance as a general design rule.
