Telefunken CDP 550A

Hi, i have this CD player for years and one day it didn't turn on, so i went to investigate and find a burnt resistor.
I swapped it with a 1k resistor and the LCD was dim, i swapped the 1k with a .680k one and it was the same dim lcd and no power to the laser head motor.
This is a long shot, anyone had the same problem?
It looks like it is not getting enough current going in.
Buttons work, LCD back light works but a little dim, front equalizer LED's look normal.
No movement of the laser head or its lens focusing system or laser light.
I even tried with an external power supply with 3,000 volts on the multimeter and no difference.

thanks.

Who is the real mfg.? I see date codes 88 and 90 but TF were bought by Siemens in '85 (I worked my first job at the Ajax AEG avionics plant in '76)
That name brings back memories.

I know that the player was bought directly in Germany after the 90's and was a set with rechargeable batteries and speakers.

I though at first you meant 3 kV!  Then I realise that you're in Europe so "," = "."

At first i used a "." then i thought people would see 3kv so changed it. It was 3.000 V on the fluke 79III.
