SOURCE: Can you hepwith my sony LCD Problem?

It could only need some soldering of the display itself. If you want to try it your self.
remove the top cover (you may need to remove the front panel also)

  1. inspect the twenty or so pins of the fl display tube especially the end ones (resolder if bad).
  2. if they all look good check for DC voltage on the end pins (20 to 30 volts)
be careful not to touch the transformer pins when unit is pluged in and the cover is off!

Hi,
The AVR have problem in its pre amplifier stage. Normally this type of cracking noise will hear because of faulty op amp (operational amplifier) ics. To repair such problems you should have through knowledge in electronics. And also need SMD rework stations Beacuse all the op amp ics are SMDs. If yo have such knowledge then i have added here the link to the service manula for your AVR.

Refer the page number page number 13 first. Its the Audio section blaock diagram of the AVR. you can see the the suspected ic in the top right corner marked as IC410. Which is the pre stage op amp for the frond left righ amplifier. You have to replace this ic( integrated circuit).

You can find the position of the ic by refering Page number 27. Its the input board . On the board you can see three ics with 8 legs(four in each side) On the left side. You have to replace the ic marke as IC410. You can find the schematic for the input board in page number 26. the The part number of the ic M5218AFP-T .

Refer the sevice manual to know how to carefully to remove the input baord.

Since you have 2 receivers, you can either use the Sony STR-AV570X or the TA-AX380. You will need 3 Stereo RCA Cables to connect your CD Player, Tuner, and Tape Player. The speakers connect to the receiver you choose using the speaker input terminals.

I am facing a problem with a SONY amplifier, model STR-DE185. On its screen is written the word ''PROTECT''. I have checked the transistors MN 2488 and MP1620 and are OK. Could anyone tell me what else...


Hi and welcome to FixYa,

Initially, the displayed message "PROTECT" is as it implies, the STR-DE185 has gone into auto-protect mode. The built-in auto diagnostics has sensed a fault and kicked in to prevent further damage to the Sony unit. In most instances, this is brought about by a faulty speaker (should be 8~16 ohms), loose/disconnected speaker wiring, strands of speaker wires inadvertently touching its opposite, overheated, ventilation holes covered, played with the volume level high for an extended period of time or a localized fault in the internal electronics of the amp circuitry.

Offhand, since DIY (do-it-yourself) repair is being done and assuming that you are comfortable working with electronic components & circuitry, use of a DVM/VOM, a soldering iron/station and safe practices with electrically powered devices, access to a Service Manual or at the very least, a schematic diagram would be a necessity.
  1. consider doing a RESET. Turn off the STR-DE185, press and hold the POWER button for 5 seconds or more or till "INITIAL" message is displayed. This would force the Sony to revert to factory defaults removing any glitches, errors in settings & configurations, presets, memories and user preferences;
  2. check if relays RY781 - to 783 are engaging;
  3. check pin 8 of IC901 (should be 5.6V);
  4. check protect switch Q784 to 786;
  5. check overload detectors Q705 & Q706;
  6. check that the MN2488 and MP1620 are not leaky

Good luck and thank you for asking FixYa.

Shutdown 10 second


Hi,

The display "PROTECT" and the auto-shutdown is indicative that the Sony STR-DA5000ES senses an internal fault and powers off automatically to prevent further damage. The fault may either be in the amplifier section, the power supply section and/or the logic board (mini computer).

Initially, try a full hard reset, that is unplug from the mains for a couple of hours to hopefully revert the unit back to factory default (that is assuming no hardware problem). Additionally, you may want to check the speaker and the speaker wires for any open/breaks or short.

If above steps are not corrective, you may need to seek the services of a qualified professional or a service center since this would require on-site/in-shop repair, knowledge of electronic circuitry and components, a full service manual or at the very least a schematic diagram with voltage readings, a DVM and a soldering iron.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
