Zenith C25A24T TV Questions & Answers
When I power up thr TV it immediately poers back
I hate to be the bearer of bad news, but it sounds like the "over voltage protect circuit" is doing its job. There is a 130 volt regulator circuit in the power supply that limits the high voltage to around 30,000 volts at the second anode of the picture tube which limits the x-rays emitted from the crt. If the regulator fails, there is this over voltage protect circuit, which immediately shuts down the power supply and the TV. Turning off the TV resets the protect circuit. Turning the set back on, will cause the protect circuit to engage again. If you're competent in electronics, it is possible to aquire the parts and do a successful repair for under $20.00 in parts, but beware, there are a lot of dishonest people out there ready to take your money. Hope this helps! Dano
I have a 25" Zenith
You will need to replace 4 capacitors. Locations and values are C 3460 which is a 25 volt 220 Mf capacitor, CX3218 at 160 volts at 1 Mf (could be 2.2Mf), C3416 at 25 volts 100 Mf , and CX 3413 at 50 volts 22 Mf. In severe cases you would also replace the powerling regulator,(STR-53041) I don't think you need to in this case. Now the green spot you speak of may be the need to resolder the thermistor. I don't recall the exact location. It is a small disk located on the edge of the main board near the power board connection( Your 110 power cord to board). I also believe there is a glass fuse near by. This is a two legged disk that is silver. Take care when soldering this. If it does break you may replace this with an RCA part# 207768. And lastly, when replacing the board back into the TV, make sure you have a good connection to the CRT with the suction cup. It should be tight fitting with no air to escape! Thanks for asking and show a few hands of support!
My zenith CD/DVD duplicator LCD light on but no ready
If the LCD light on your Zenith CD/DVD duplicator is on but it is not showing as "ready," it is possible that there is an issue with the duplicator's internal components or settings. Here are a few troubleshooting steps you can take to try and resolve the issue:
Check the disc trays: Make sure that all of the disc trays are closed properly and that there are no discs stuck inside the duplicator. If a tray is open or a disc is stuck, the duplicator will not be able to operate properly.
Check the power source: Make sure that the duplicator is plugged into a working power source and that the power cable is securely connected to the duplicator. If the power source is not providing enough power, the duplicator may not be able to operate.
Check the settings: Check the duplicator's settings to ensure that it is set up correctly for the type of disc you are trying to duplicate. For example, if you are trying to duplicate a DVD, make sure that the duplicator is set to duplicate DVDs and not CDs.
Reset the duplicator: Try resetting the duplicator by unplugging it from the power source for a few minutes, then plugging it back in and turning it on. This can sometimes resolve minor issues with the duplicator's internal components.
If none of these steps resolve the issue, it is possible that there is a more serious issue with the duplicator's hardware or software. In this case, it may be best to contact Zenith customer support or a professional technician for further assistance.
