TiVo SYMPTOMS
| TiVo Repair and Troubleshooting: TV Only Shows a Black or Blue ScreenYour TiVo: Symptoms you may be experiencing When powering up your TiVo, the TV shows no change at all. Often, there will also be no lights illuminated on the front panel of the TiVo itself. Sometimes, in this situation, the fan will actually still spin and send some air out the rear fan grates. Fix my TiVo! - Solutions Most often, this behavior indicates a bad power supply. A replacement power supply will usually fix the problem. Each TiVo needs a very specific type of power supply, so be sure to find exactly the right model. WeaKnees sells parts for most models on their TiVo power supply page. Also, for most TiVo DVRs, you'll need a Torx T-10 to open the TiVo, remove the power supply and install the replacement. More Information about this problem Many TiVo users try testing the output voltage of their power supply to rule this out as a source of problems. While it's true that the power supply should be sending 5v and 12v signals out the hard drive power cable, power supplies that test to those voltages can still frequently cause TiVos to fail to boot. The reason is that the power supply is also responsible for special signaling through another cable, usually a flat white "Parlex" brand cable, directly to the motherboard. And there's really no test for the signals on this cable, short of just trying a replacement part. |
