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.

Hi malumbender,
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.

SOURCE: Burnt Zener diode... Voltage spec??

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.

Hp2710m capacitor blown

Look for any short circuit around, short zener diode, short transistors or diodes. Look for any excess voltage in that area where you found blown capacitor. Then replace it and see.

TDA-03211c 32 inch Polaroid replaced two capacitors now it turns on runs but shuts off in 10 minutes or so what could it be?

It is having higher voltages in some sections, might be a leaky or open zener diodes. Have you replaced the capacitors with correct voltage and watts rating? This is a case to be handled by a qualified service technician.

When i turn it on nothing happen the standby light stay on.what to do?

you have to check on system regulator and main Program ( EEPROM),you should check parts, such as: elco, zener diodes, and transistors and final IC program, you have to check 5 Volts = VDD from the power regulator IC EEPROM, there must be an incoming voltage available to drive power on the entire circuit TV.

Sylvania SSL2006 dead, won't turn on. fuse is ok,

Hi larry
Since you know electronics that will make the explanation simpler;
On your tv model there is a very common problem that you may want to look at;
There is a small board on the right hand side(backlight inverter board),
Look for a shorted D309 , it is a 9.1volts 1watt zener diode.
As i said it is a common problem for your model.
But there is also the power supply;
All lcd tv`s nowadays it seems end up with bad capacitors in the power supply,
You can recognize them by their rounded tops and you`ll find them at the output of the power supply along the 5/12 and 24volts line.
But especially on the 5 volts line.
If your not sure which ones then replace them all (there might be 6 or 7 of them) it won`t hurt and eventually they will go anyway.
Hope this help good luck

Delay light is flashing on tv, but wont turn on. Not sure if problem is tv or remote? Dont see light on remote when push in buttons?

The problem with the unit is power supply part number,MLT166A.If you can not find one you can try to fix yours.First you have to take out power supply,Replace 3 electrolytic caps EC18,EC19,EC20 all are 1000mf at 16 volt.Then find Z3 on same board,it is a 27 volt zener diode 1 watt,part number 1N4750A.Put board back in then unit should work.

AKAI 27" LCD Power Supply - Replacing capacitors and diodes

You can always replace a lower voltage cap with a higher voltage just don't change the rating... In fact you could replace the 16v cap with a 400v cap if it would physically fit.
As far as replacing a zener under the heat sink, yes you'll probably have to remove the heat sink itself if it's blocking. And as for any words of wisdom - if your repair is unsuccessful try replacing the module. Shop Jimmy usually has them used if you don't want to spend full bore and order a new one.
Good Luck!

Zener Diode question

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.

Sylvania 6632 LG blows fuse when plugged in

I too had this problem. I read some posts on this site about how to repair it, and low behold, they worked! I took the back off of the TV, and the first thing I found was the fuse was blown. With my meter, I checked the first 1N5406 rectifier diode after the fuse, and found that it had shorted out. Then I had to learn to desolder the diode, which I learned about on Youtube. I bought a pair replacement diodes at Radioshack for $1.49 and four replacement 125 volt 4 amp fuses. The whole repair cost about $5.00 and a few hours about learning about electronics. The TV works great! Good times!
