Bose Solo TV - need SMPS schematic

[dobrykamil]

Hi

I'm looking for SMPS schematic of Bose Solo TV. Does anyone also know, what is the output voltage of that psu?

Thanks in advance.

Yes, I've got that service manual already, no schematics inside at all.

Look at Manual in post #2:
Page 25 show flyback transformer T1201 for 24V 2.5A. BOSE P/N 370743-0010 .
So it is more likely to be 24V power supply,
Page 20: the filter caps are rated at 1000uF 35VDC for C1321, C1318. C1316 is 220uF 35VDC.
Cold side Rectifier page 22: D1301 SCHOTTKY RECT., 5A, 170V, COMMON CATHODE, BOSE P/N 329305-0010
Page 23: U1201 is the SMPS IC, BOSE P/N 348216-0010.
Page 23: LDO and Buck regulator ICs: U702, 704, 705.
So lots of info on that service manual to get you started.
May be you should upload the pictures.

Hi.
Yes, you're absolutely right, I should have done that in the first place I've found that smps controller is kinda dodgy and one of the mosfets has short. I still have psu from Canton DM50 which provides output of +23.5V, so I'll see if everything else is fine before I order some spare parts. Many thanks Budm for a tip!
