You will need to purchase small box that converts your phono magnetic cartridge level output to a higher line input level before it goes into the TV input jack. Radio Shack used to sell a small amp for about $20 that was made just for that purpose and was called a stereo pre-amplifier and was model number SPA-50 and it plugged into the standard wall outlet to get power. Back in the "old" days when phono magnetic cartridges first became popular some of the older home stereos had only the ceramic phono style inputs (or an aux. input) which were about the same input level as a tape input or aux. input (or TV input) and so you would have to use one of these adapters to boost the newer magnetic cartridge signal up to the same level as a ceramic cartridge in order to use a new style of phono. This will fix your problem if you can find one at Radio Shack or some other place, perhaps on the internet. Hope this helps you.
