About Tv Tuner
Sometimes i got emails from fellow members about whether the TV tuner can be repaired or not. I told them that the components in it were very small and have complicated design. Some of the components do not even have part numbers especially the small SMD transistors and the schematics are hard to find too. You may look at the tuner board in the below photo. Some of the tuners have the silicone glue covering the whole board making troubleshooting even tougher. I told them, the best is to replace with a new one which can save their time. If they insist that they want to try repair they always can go ahead. Dry joints in the Tuner especially the pins are quite common. I wonder whether you all repair the tuner or have it replaced? Do you know of any website/company that repair TV tuner?
