Re: TX802 power supply issues

Bad filter caps may explain what you described so replacing them makes sense. I would leave the power resistors alone.
Good Evening (Well it is here)
I have some issues with my 802, Some times it would boot and some times
I got a initial boot screen and then it would dim.? After a power cycle
it would work. However, two weeks ago it wouldn't pass the boot screen.
The circuit diagram gives +5 and +15 however my power board gave 4.6 and
14.3. After tweaking the pot Im now back up to 5/15V however, this took
quite a turn.
So This brings on a question why did the voltage drop is it bad caps?
and how long can I use this before it start failing again and I need a
tweak to Max...
So I recon i have to recap the power supply and replace the large 1W
power resistors. Any other pointers?
