    what do i do about the flyback???

  • ajerry333333 Jan 17, 2009

    After taking the back off, i tried to see where the clicks were coming from but I saw nothing, I unplugged the speakers from the board just to insure that the sound wasn't from there, it wasnt. And another thing....I have to unplug the set and replug in order to get even the clicks because once i turn the set on....the power button wont work anymore. so i have to unplug it to try again.

^.^ hi..
I see that your TV's high voltage flyback is leaking out.
or the flyback cap to the CRT aka picturetube is dirty, or it has a open insulation.
(Warning: Flybacks are extremely dangerous, it has a high voltage that kills. becareful.)

    As what I said this is a very high voltage and could kill even when it's plug is not connected or turned off.



    but if you are willing to do, well I'll provide you how to do the job.

    First open the TV.

    Then check where the sound comes from.

    By turning it on and observing the unit.

    If you have found where is that sound comes from.

    Reply me what you see and hear, discribe it as what does it look like.

    hmmmm....

    ok... maybe the click that you hear is coming from a relay that switches the unit on.

    and try to resolder your unit.

    sorry about that sir.

    TVs are really dangerous because of their high voltage. so fixing them needs caution.

Why wont my 2001 fxdwg wont turn over with good battery ?


When you try to start the bike, does anything happen? Noises? Clicks? Or is it silent and nothing happens? If you hear a click or it try's to start but doesn't turn over. If nothing at all happens when you hit the start switch then you most likely have an electrical issue, versus if you hear the starter click or try to start to bike, then that would mean a mechanical issue.

It wont turn on


You give us littel to go on here. Can you describe what happens (if anything) when you attempt to turn on the set? Is there a click? Is there a standby light on the set before you try turning it on? Is there sound or nothing at all?

While possible, dead sets are not usually caused by a blown fuse. If the fuse is blown, then the power supply will need work. If not blown, the power supply may still be the problem. Please update this with any other symptoms and we'll try to assist further.

Thanks,
Dan

My ps3 wont power up


try powering the system up by HOLDING the on;off button , it will reset all your audio and video settings . then plug the system using the AV cables (default) .

else, you should take it to an assastance centre for hardware issues checking . can be a problem with your RAM or GPU units that makes the system unable to startup it's firmware .

Dryer Won't Start


Make sure it has power. Then:Check the door switch. A little lever sticking down through top right of door opening. If it is not there you will need new door switch(sometimes the little lever breaks off). If it is there and does not click when you press it in you need a new door switch. if it clicks when you close the door then you have a bad thermal fuse.The thermal fuse is found by taking the back of the dryer off. The fuse is an oblong white plastic piece with 2 wires attached.

Door switch part number 3406109
Thermal fuse part number 3392519

Turn off itself and wont turn on. There is a noise, when you plug in. Click, click


Your description indicates that the power supply has failed; the noise you are hearing is probably caused by a relay that is interrupting the AC supply to avoid damaging the supply any further or causing a fire.
Disconnect your set from the wall and allow several hours (overnight is better) so that dangerous voltages have a chance to discharge.  You will have to gain access to the lower section of your system to look for a separate board with larger components on it, some cylindrical (capacitors), some block-like (chokes and transformers). If you can locate this board, it should be user replaceable.    

The next step would be to look for unique markings on that board looking like an assembly number. With that in hand and the model number of your set, look for the RCA service center in your area and call them to determine whether they have a repair or replacement assembly.
If only a replacement is available, keep the failed unit for possible repair in the future when the new one fails since mfrs. will not have entire assemblies available in a few years.

Turn digi 002 on and the mute light keeps stay on


Hello,
I just had the same problem... It has to do with the connectors from the power harness. Found this on the internet and it did the trick for me...
Goodluck!
It seems like it's only a matter of time before the digi002 (rack and non-rack) have this problem. You'll go to turn it on and the mute light turns on and nothing else. You don't hear the 3 clicks that you usually hear when turning it on. Your computer doesn't recognize it. Then you start swearing and promising to quit recording forever. After all that happens, you have 2 options:

1. call digidesign. they've been replacing the power harness (source of problem) for just about everyone, even if you're out of warranty and it's free (including the tech support over the phone). don't pay them anything. maybe shipping.

2. most people seem to have the same problem after a while after getting their new power harness. lots of people are saying it's not even the harness - just the connectors. so last night i had this problem and i opened up the top of the box and unplugged and plugged back in the little rubber-covered wires going from the power cord to the rest of the 002. turned it on. works fine. i may try to use some of that connector-cleaner from GC if it happens again.

so if you find this happening, don't panic. try the above. takes 5-10 minutes (only because of all of the screws)

Wont turn on


OK, it looks like a power supply problem. The click you are hearing might be the shutdown relay connected to the overcurrent circuit. This might be indicating a problem in the Hv section of the TV. To get the tape out you can restore the power supply or what you could do is to try to access the drive motor and find the load and unload gear and try to turn it to take the tape out, this has worked in the past at my shop. If you have no experience in electronics I would suggest you not trying to repair this set because of the danger involved. Take it to a qualified repair shop.
