Hi, The Company in the first link below is supposed to be the aftermarket support point for Daewoo. Try here first: http://spares.alliedappliance.com.au/part_enquiry.php

The try this one.

Since you did not state any part numbers I am helpless to help you find a replacement. FYI most board failures that I have experienced were condensation / corroson/ water caused. The electrical runs on the boards end up shorting and then take out the PCB transformer and fuse if there is one installed.

Let me now if neither of these companies were not able to help you. I will search again via Daewoo corporate if I need to.

Thanks for choosing FixYa,
Kelly

Hi, nad going but no sound from speakers. can get FM but only up towards full volume.


Checker speaker wiring on back for shorts, if okay! the audio drivers and outputs are highly suspect, at this point I suggest a serviceman because of the complexity of the surround sound system.

Hi, I have a Daewoo air conditioner split (model dsb-070L/dsb-091L/dsb-070LH/dsb-091LH, I'm not sure about the exact model number). The remote is not working anymore, and I don't know why;...


Hi Josematamoro

Did you find a solution to your problem. I have the same problem and not sure what to do. I have contacted a airconditioning maintenance person who said he would try and look for the part to fix it.

Hi i have a Daewoo DSB 180LH air conditioner but the previous tenants have lost the remote control, what can i do?


Hi Cladia,

I had exactly the same problem! Fixed it by buying a Universal All In One Air Conditioner Remote. Tried a couple which didn't work, but finally found one which did - the Chunghop K-1028E. I purchased it online for $20 inc delivery to Australia.

Good Luck!

Regards,

Will.

Ballast Verification Process
1. Short out door switch (SP001)
2. Apply AC power and wait till DM module boots
3. Press power switch and observe spark gap on ballast
4. If spark gap arcs, suspect Lamp. If color wheel starts but ballast won’t strike
lamp, go to next step.
5. Measure BP252 on AC IN CBA for +300Vdc. If missing check door switch, cable
from AC IN CBA to switch and AC IN PCB. If correct go to next step.
6. Monitor pin 2 of BT251 for Ballast ON command from Light Engine. If present
suspect Ballast. If missing suspect Light Engine. Pin 5 of BT251 starts at 3.3V
after power switch is pressed and drops to .18V when the Light Engine sends the
start command. No change on pin 5 indicates Light Engine is suspect, change
on pin 5 with no ballast start, ballast is suspect.

Note: Lamp may arc but not start. Pin 5 of BT251 is "LAMP LIT" and goes to 1.48V
when lamp is lit. If ballast strikes lamp but lamp won’t stay lit, suspect Lamp.

Right Channel Not Working


I have had the front, left and right channels go out over time. I have fixed all of them, and each time it has turned out to be a cold solder joint. While I love NAD and will continue to purchase there equipment, this generation is plagued with poor workmanship.

To fix the channel going out, I removed the top cover. Back cover and 2nd card from the left (looking at the receiver from the back side). This card handles all of the audio processing. I have found cold solder joints all over this board which has caused channels to suddenly go quite. I have never found a bad component. Also, I have cleaned the interconnect to be backplane (board that the audio processing board connects to) in the case of the center channel going quite.

If you have poor FM reception, the first board from the left (looking at the receiver from the back side) may have a cold solder joint on the coaxial connection for the FM antenna.
