Just got one of these the other day.
It looked too unused and too new to have any problems.
So I decided to strip it down and find out what the heck was going on. I figured some of the capacitors had dried out, and decided to do an circuit analysis of the power supply and connectivity.
Well, it is a design error.
The power supply does not have enough of a level of high quality buffer capacitance on the power supply board.
It MUST have that, in order to deliver the micro-transient current draw that happens thousands upon thousands of times per second. The lines area also too long, too far away from the power supply.
when you add the long power lines up, with the aging of the small undersized buffer capacitors, with the lack of proper size of buffer capacitors, you get a recipe for failure, in a very short period of time.
Oh yes, it will work fine when new, but..it is only a matter of time.
This is apparently the modern way, with all this modern digital equipment. Things that are specifically under-designed, designed to fail, designed like a fuse, to make you throw away the equipment, after a certain amount of time.
The LCD tv's are the worst for this lying thieving garbage trickery. They save a total of a dollar or three, at best, but your TV lasts about two to three years less for it.
In this case, with this Toshiba DVR, I went into the power supply, and swapped out capacitors C461 and C202, which are 33uf/35V capacitors. I put in 330uf 35V Panasonic FM series capacitors.
The unit fired right up and now has zero issues.
Essentially, it would read CD's and play them perfectly, but would not recognize any DVD's.
Once those capacitors were changed out, it then worked perfectly.
To clarify, this the Toshiba RD-XS35 DVD HDD burner/player, from 2006-2007.
