switch on and it says prot and goes off
darren, The prot means it goes into protection mode and shuts itself down to prevent any further damage. It is possible that your DVD player has detected a problem in the amplifier section and is shutting down to prevent further damage. I would check is all of the speaker wiring. Sometimes it will indicate that the internal fan is not working or the internal sensors have failed to recognize that the fan is functioning. Hope this helps, good luck.
I think these has something to do with internal amp all you need to do is to remove sound ics and put new one’s thats all
I have the same problem. DVD enters in protection mode. Checked power supply and i have no 12V and 3,3V. i found that capacitor 6800uF/6,3v was short circuit . Change it and everything is working.
I have a Blu Ray Samsung HTB-H4500R. This player worked for a few minutes before showing Protection message. Fan and inside cleared of all dust, but no improvement, even with lid off. Also no signs of components getting hot, or speaker wiring problems. Eventually fault cleared by removing front control panel, disconnecting the one ribbon cable and brush cleaning the reverse side of board with alcohol (where there were deposits of a sticky nature which were there from manufacture). Dust was attracted to these deposits causing a malfunction of possibly high impedance circuitry. The clue was that I had read elsewhere about disconnecting this panel on other Samsung Blu Ray players which cleared the fault and using the remote control for operation. I think the sticky stuff was used on screws going into plastic, and may have migrated with time. John Pearce
To solve that problem on Samsung tx35 check simply whit and ohmmeter which is connected between the +12V and GRND comming from PSU. If it is shows you short circuit than change the PC1 capacitor (330mF 16V) on the main board. No headache No protection error :)
Hi Thank you so much this was really very helpful Kind regards Candy
