QYT-7900D No Sound Intermittent Audio Troubleshooting & Repair QYT-8900D KT-8900R Bad Solder Joint

I was having no sound / Intermittent sound on my QYT-7900D. I really like this tiny radio. I like the quad monitor and band. I have it programmed for just about every FM band for emergencies and inter car communications. If you sound want to watch this video the fix was to resolder the audio amplifier part number LA4225. I used a little flux and resoldered the joints and were back in business.
