Beovox 5700 TWeeter impedance
in BeoVox · Nov 26, 2024 17:44 GMT

Hello; Can you please indicate to me the resistance value of the HF 2000 tweeter of the Beovox 5700. The beovox 5700 is a 8 Ohms speaker as well as the installed Philips boomer and the medium but I have a doubt about the…

The LDR components were the culprits I used a repair kit from Beoparts and put back the LDR in the 1900, everything is fine The 1900 is back to life and sing again Thank you Sonavor

Actually I unsoldered the LDR, more easy to open it The metal cover is glued to the black plastic support see attached picture The lamp is dead

The lamp is probably OK as measured 17 Ohms However I have ordered a repair kit for this LDR By the way, is there a trick to remove the cover of this LDR? Is it glued or just clipped?

Hello, Thank you for the help I used a one Khz tone generator connected to the recorder input and the signal arriving at the balance control is very low I will open the LDR by tomorrow for checking Alain

I could measure the IL1 lamp resistance between emitter TR24 and 15 V and found 17,7 Ohms is this value OK? If yes the problem is elsewhere, any thought?

Hello, The input signal is not reaching the balance potentiometer It is stopped at Test Point 200 or 300 and not going through R226 and R326 I suspect IL 1 to be faulty and would like to know how to test the lamps inside…

The culprit was R126 measured 40 MOhms

Yes! I used FM4 to activate FM5 and it works as follows: the R122 and R126 lifted from the IC6 side the R122 connected in place of R126 on IC6 side So the issue is between TR21 and the IC6, to confirm I have to replace t…

The signalling only is on an other PCB not the commands

Yes it was always there (By the way I measured the lamps they are 18 Ohms each instead of 12/14 Ohms as a consequence, the voltage reference for muting measured at R3, 33Ohms of PCB 5 is no longer 2,5 Volts but 1,9 Volt)

No it does not if I am on an other entry However, it starts the 2400 when in stand by but does not allow to use FM5 the corresponding lamp is not lit, but in that case I may switch to any other input Alain

actually it was one leg of the P6 switch to be grounded, stangely it was not. If left open the front end is missing the voltage for the varicaps and it is free running

Hello After checking some parts ofthe 4400, it appears that one end of the P6 pot for adjusting the channel number 6 is left open when it should be grounded. To be corrected of course. Hopefully can be done without diffi…
