| How to convert the TV in my boombox? |

Hi, here is a picture of my boom box with built-in analog TV. Is it possible to somehow get the TV in this to connect to a composite video cable - or is there some other way I can control the TV signal that comes out of it? Thanks for any help. |

Get an RF modulator, then you can put composite video and audio into that and send the RF output into the antenna port on your boombox. As long as it can tune in TV channel 3 or 4. Something like this: RCA Compact RF Modulator (CRF907A) https://www.amazon.com/dp/B0014KKV7W Sent from my Fi Moto x4 using Tapatalk |

It will still be a crappy mono CRT display, with very questionable reliability (as its got to be something like 30 years old), so IMHO the best option would be to totally remove the CRT assembly and remove or disable any associated HV circuitry, storing the parts if you ever want to be able to restore it to collectable condition, then figure out how to integrate a touch-screen media player running Android. |

What's with this stupid trend of hacking up classic stuff and installing crappy touchscreens in everything? If you want a touchscreen Android device, just carry around a tablet. The CRT is the only unique aspect of those old portable setups. They are actually quite reliable, the only fault I can recall ever encountering was a bad electrolytic capacitor and that was in a cheap Chinese B&W set that had a lot of hours on it. Mose of those inexpensive B&W TVs were based on one of just a few ICs that handled all of the video processing. Many of the TVs had composite input but some did not. If you want to add it to that TV the first step is to look at what IC is in it and then find a datasheet. If you are lucky, the components to handle the composite input may already have locations on the board you can populate. |

Well the original idea was you could go somewhere, and take easily portable entertainment with you: Music, radio or even watch a broadcast ball-game. It was never the device of choice for sitting around watching cable. The TV signals it uses are no longer transmitted, and the need for a separate signal source outputting composite video (and maybe a modulator if you don't want to mod the boombox for a composite video input) removes the easy portability advantage. Modding it to add an Android device is the nearest you'll get to its original functionality, if there's a livestream of the events you want to watch. Of course its a very niche concept, and I personally would rather use a phone or tablet + good bluetooth speakers, and sell the boombox to a collector who will value it in orginal condition. |
