TV Repair Questions? Ask a TV Technician for Answers ASAP
Hello and sorry to hear you're having trouble,
they don't make 37 inch sets anymore, so you'd either have to go down to a 32, or up to a 40/42/43 as the typical sizes.
The newer ones have much smaller frames and hidden speakers though for the same approximate footprint you can upgrade to a 42" set.
here is a suitable replacement tv that I'd suggest for you: https://amzn.to/37VKlKi
