Won't power up, LED flashes with a clicking noise from the speakers when plugged in
The title basically says it all.
If I have the unit plugged in, the power LED flashes and the speakers click every few seconds pretty regularly. Seems it is a fairly common problem. I found another solution where you reset a similar monitor it by plugging in the DVI connector right after click, but I was unsuccessful after a number of tries.
I disassembled the unit and got into the PS and disconnected ALL the connectors. I measured 5V and 12V on the PS and they remained stable.
However, if I connect the control board and connect the power led or the speakers or both, it still does the flashing and/or clicking (respectively, of course).
I peaked at the digital board, but thought I would write something up here before I do anything TOO stupid. I am wondering if there is any way to mimic that resetting of the digital board through the DVI on the board itself (maybe some way more reliable. . . like maybe I can hold/short a reset circuit or something).
Re: Won't power up, LED flashes with a clicking noise...
The major problem with this system is memory deletion.I mean the programmable rom ic bordering the ps.What you need to do is unplug the no. 5 pin and plug it back immediately after switching on i a sure you it will be working.

1. check the power, is the LED indicator light when you turn on the power?
2. assuming the power is ok, unplug the phone plug from the computer, plug it to an ipod or any mp3 player's phone jack, still no sound? here are the possible causes:
a) broken internal copper conductor from the phone plug,
b) busted amplifier chip
if you have basic electronics knowledge, these multimedia speakers are easy to repair, otherwise replace the whole unit. ;-)
U have tools like a soldering iron,desoldering pump or roll of desoldering braids,a roll of solders and understanding basic electronic also can do basic soldering?This problems,most of the times are causes by those dying soon to be dead components call capacitors on the power supply board.Yes,take ur tv aparts,the power supply board,that the board,where the power a/c cord plug into it.Check the power supply board for those dying soon to be dead capacitors parts,it alway bulges up on it tops or puffing up on it tops.Replaced these dying soon to be dead capacitors parts,will solved ur tv noises clickings,power LED light indicator will stop flashing.Tv will power up normal again an work.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I had exactly the same problem. My unit worked fine until a loose power cable resulted in the receiver being turned on and off a couple of times in quick succession and then after this the a/c in light on the rear speaker was lit but the wireless link light would not come on (and the 'W' on the main unit flashed constantly). The solution for me was basically a reboot. This is what I did; - unplug the wireless receiver - unplug the main unit - remove the digital transceiver unit from its slot in the back of the main unit - plug the main unit back in and turn it on - the 'W' won't flash as the transceiver has been removed (not sure if you if it's necessary but I made sure it was producing sound to the front speakers) - unplug the main unit again - reinsert the digital transceiver - plug the main unit back in, turn it on and set it to produce output/sound (the 'W' will be flashing) - then plug the wireless receiver back in again ...presto the link is made, the 'W' stops flashing and the rear speakers work again.
Hope this elaborate reboot works as well for you as it did for me.
Ur tv turn on now,hear alot of clicking?The tv LED light "lamp" on front panel flashes or light up?The tv projection lamp is dead.The Ballast board dead too,if hear alot of clicking?The ballast board help to ignite the projection lamp.
Protect mode will kick in whenever a fault is detected.
You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.
Causes that can start protect mode are:
Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.
Bad speaker wiring. Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.
Internal fault. Internal
fault is the natural cause for protect mode. If all the above did not
work, then the problem is a blown component or an internal fault. In
this case the unit must be taken apart , tested and repaired by an
experienced person. If the unit is less than one year old, or if you
want to get service, call Sony at the phone number listed on the
I had this exact problem. The clicking is something to do with interference from the power supply cable. It seems that facing the wireless unit in the most obvious way ensures that the power cable and the right speaker cables cross. All I did was turn the unit around so that the wires no longer crossed and magically the clicking sound disappeared forever!!!
