It's great that several parts of the unit could be salvaged for future projects, brilliant as always 📼

I really enjoyed this type of video. How you explained the various components and there function. Maybe you could do another one like it. Thanks for sharing

All of the teardown videos I did this year so far have been done like this, with lots of explanations. So if you have not already seen them, you might be interested in watching those. But I will surely make more videos like this in the near future :)

​@@DrCassette... Reverse AM / FM tuner on power board. I'd rather use a radio boombox CD player with radio separate switches for getting quality stereo sound. A TV system of a DVD player won't worry about great FM sound when designed to go to low power even if they are two 5 Watt (like 8 ohm) speakers. If not a boombox quality FM to speakers quality maybe to a high powered amplifier system totally designed for music sharp clarity. As far as video to presumably an analog TV I would say yes on doing anything to get picture clarity for up to 42 inch TV tubes in analog TVs. Blue Ray players and above work with total digital signals to all types of LED and high definition TVs making this unit a last 2007 picture tube DVD player with semi okay stereo really not designed for high amplifier or boombox musical sounds (noting Dolby audio before CD players with the latest casette tapes and with Dolby printed on them).

I really enjoy your video's i have learnt so much

Sunplus all-in-one decoders are in many late era Chinese-made DVD players (think '08-'12), even mainstream brands once they produced their last models and moved on to Blu-ray.

I bet it's a Class D amplifier board inside this DVD Home Theater Receiver. but I was wrong about that.

If this system was a bit newer, it would certainly have a Class D amplifier. But this is from the mid 2000s, and Class D was still a new and unusual technology back then.

@@DrCassette these TDA Chips are very complicated as you stated in the video. 🤷🏻‍♂️

Genau den selben hatten wir letztes Jahr im Urlaub in Dänemark im Ferienhaus das Ding ist unglaublich heiß geworden ist aber auch kein Wunder denn das Teil musste 5 Lautsprecher + Subwoofer betreiben.

Very informative, thank you!

I've done exactly what you are doing now from 1995 to 2000, I find 100 reasons for each single item I collect and how useful it will be one day, I ended up with piles and piles of parts, One day I decided to declutter my life and throw everything away since I've never gotten to use anything I saved. I hope you don't end up like me.

I am not a hoarder. I do sort through things regularly and throw out what turned out to be less useful than expected. I enjoy being able to do projects and repairs without having to order parts in advance, so I would not want to miss my large collection of parts.

I still have a system like this with speakers and its got a coax input for 5.1 forgot I had it.

I always save the power supplies and motors.

That tuner might be using Sanyo PLL chip that is controlled via Sanyo CCB. I repurposed one that I got from a mini hi-fi and I controlled it using arduino.

I had a Panasonic thing like this but upgraded to a proper amp

A DVD player with integrated receiver, haven’t seen that before. It looks like it was a real budget system. Sunplus still make a DVD player SoC but they haven’t got any Blueray player chips by the looks of it. They mention on their website that it is a 32 bit risc cpu core, but unknown if it is MIPS or ARM based.

they still used vfd in 2000s ? i thought leds became standard already.

VFDs were still quite common back then, and you can still find them in some products today.
