When the "protect" indicator goes on, it's the system's way of protecting itself from a more serious problem. What has likely happened is that an internal component has failed. If there wasn't a protect circuit, the system could overheat, catch fire, or cause an electrical shock. There isn't too much you can do about this... taking it into a shop to get it fixed will very likely cost much more than if you bought a used and working version of the same model. Extracting your CD's will require you to partially disassemble the until.

One last thing you can try is to check the manual's troubleshooting section. If you don't have the manual you might be able to download it. In that section, it may provide some advice about what to do when the "protect" indicator appears, or how to extract the CD's if the unit fails somehow.

    One other thing--try disconnecting the speakers. Sometimes there can be a short in a speaker that will trigger this... or if you've got too many speakers connected, the ohm load will trigger it as well.

Sony Brava Blinking Code and their meaning


Hello,<br /><br />Below are some blinking code interpretations for your Sony Brava TV;<br /><br />ONE Blink--- not used for the self-diagnosis<br /><br />TWO Blinks---B+ over current protection (OCP) , unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.<br /><br />THREE Blinks---B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.<br /><br />FOUR Blinks---No Vert. Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted. Check IC1509, Q1505<br /><br />FIVE Blinks---AKB circuit (AKB), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. Also unit be in IK blanking, try turning up screen slightly.<br /><br />SIX Blinks---No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately. Check C515 & 516 and the jungle IC, IC206.<br /><br />SEVEN Blinks---High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.<br /><br />EIGHT Blinks---Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code. Check IC406 audio amp, PS401 and 402.<br /><br />NINE blinks - Replace D 6116 and D 6301 on the "G" board, do not resolder as this will fix the problem temporary. Or Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing, then change the switching regulator on the "G" board or check connections. Make sure the regulator is -12 or -13 (negative).<br /><br />TEN blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.<br /><br />Intermittent problems ?? This is a great feature. You can also bring up these fault codes ON-SCREEN to see a list of the problem numbers with the abbreviation of the problem and the number of times this problem has occurred. This is slightly different than entering the service mode. To see the diagnostic screen, Press the following buttons:<br /><br />Display, Channel, 5, Vol Minus, ( Not plus ) then Power. This brings up a screen with a list of the problems and number of times they have occurred. Each of the problem names is abbreviated as, "OCP", "OVP", "V STOP", ETC. We have repeated them in parentheses in the text for the "Blinks" described above so you can correlate between the diagnostic screen and the blink codes.<br /><br />So, now that you know about these self-diagnostics, how do you use them? Say that you have a set with a black screen. You see that the LED is blinking 4 times....This would tell you that you have no vertical and that is why the video is muted. If it was blinking 6 times, you would know that you have a horizontal fault.<br /><br />I hope I have helped someone.<br /><br />Regards.<br />

Hi Frank,
Changers and Mega loaders are often with problems once they age. That is why it is a good idea to have a Technician who can work on these at bay when things go wrong. It can be a bad belt, dead motor spot or even a jammed part of the mechanism. I have unjammed many a plastic mechanism and they warp and go out of position which is why I use only single players.

PDX 4.100 In Protect Mode..


According to the manual, the issue could be:
  • Internal issue with the amp circuitry.
  • A short on the speaker output(s).
  • Power source voltage is too high (aka above 14.5V).
  • Overheating.
The easiest thing to do is to try removing the connections to the speakers at the amp and see if the issue disappears after each set has been disconnected. Keep removing wires until both LEDs stay blue.

Burns cds


Hi,
This could be several issues.
Firstly there could be a format compatability error.
if the burner is looking for Wavs and finding MP3s, then you,ll need to convert the formats, for compatability.
Secondly this could be a copyright protection function, if the cd your trying to copy is protected, then the writer will refuse to copy the files. ( can Sometimes happen if downloaded )
I,d suggest locating some better Software, for your writer.
Or re-installing your original packet-writing software that came with the writer.
Hope this points you in the right direction.
Mike @ compurepair.
