    The hum is probley the filter electrolytic capacitors, which filter the 60hz out of the house power..they are the tall metal capacitors and usually around 10mf or up to 50mf...you can use modern caps..but they have to be at least the voltage marked on your original caps...and usually are like 450volts...replace these and go from there..

Why does plasma tv not come on?


Check the power outlet. Try connecting it to a different power outlet. Look for any jammed buttons on remote. Retry by removing batteries of the remote and operating the TV from the control panel. If nothing works, the power supply has gone bad. It could also be a blown fuse.

Tv unit , zenith is blown notworking, please help


When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

Microwave has no power, no lights, nothing at all. Yes it is plugged in, and yes, the outlet has 115v going to it.


unplug the oven, remove the cabinet if you feel confident in doing this. next, follow the cord from the microwave's cabinet input and look for a fuse. Little round rectangular tube. It is about a half to 3/4 inch long. look on the fuse, it will have a rating like 3a/120v or 5a/120v what ever it is, replace it with the correct value. remember MAKE SURE THE CORD TO THE OVEN IS UNPLUGGED AND USE ONE HAND TO REMOVE IT USE A PAIR OF NEEDLE NOSE PLIERS, MAKE SURE OTHER HAND IS IN YOUR POCKET. After replacing fuse, and putting case to oven back on
Plug it back in, turn on the power and try the oven. if nothing happens then take to a repair center. remember before going inside after cover is off,power off, hand in pocket and touch nothing else only the fuse. if you don't feel confident with this , take the oven to a repair shop. probably fuse is blown. good percentage of ovens are thrown out because no one knows this.

I have an old Zenith console radio model #8A02. Do you have any idea what it is worth and where I can purchase the tubes for the radio?


My problem had nothing to do with the Radio Shack VGA PC Camera Webcam. I was asking about an old Zenith console radio model 8A02. I was trying to find out where I can still buy the tubes for it and what the radio is worth.

I believe you have a shorted transistor on the crt board on the back of the picture tube which should be Q5104. Let me tell you my experience with these Zenith's The original problem is the picture tube shorting out and caused this problem. If you replace the transistor the same problem could arise again because of the tube and it could even knock out the main board power supply. I have seen this happen. And I have put in the transistor and no problem. You can get one at the Radio Shack by taking the bad one out and get them to cross reference it for you. All Zenith transistors have a prefix number (not on the transistor) which is 121- (with the dash!) and the number on the transistor The new one must go back in the way it came out! I recommend someone with electronic soldering and desoldering experience. Hope this helps

Apple LaserWriter 8500 not turning on


There is a glass-tube fuse inside, near the power switch that blew on mine a couple of years ago. Being the curious type, I popped off the side cover to see if there was any obvious reason, loose connectors, burned resistors, etc., and found the blown fuse. Can't remember where I got the replacement, but think it was Radio Shack. It's a common type.

No Power to TV


There is no reset button on these new sets,your set has complete power problem since you have no lights no clicks,this might have happen because of lightning or power surge,either one creates a lot of damage,if you are familiar with tv service you can check the main fuse,he should be close to where the power cord comes in,if you find the fuse blown it needs to be replaced with an exact replacement for AMPS rating and VOLTS rating as well as size,if the fuse is blown black we might have more problems ahead in the circuit and it will blow up again as sonn as you plug the tv back in,if it blows again it will need a more involved repair,the problem could be in the primary side of the power supply,if you are not too familiar you should seek the help of a servicer a least for an estimate but if you suspect power surge or lighting damage dont invest any more on this set and get a new one.
