Hi we need a power supply for a powerspec monitor v30dmbt-u21. The part number is 6693006610.
I decided to remove the offending power supply, and searched on-line and found this company:

Tatung HOAU242001 6693006610 power supply for tv
Using their services, perhaps I might be able to breath new life into this monitor.

I had a problem with that SMPS that was in a Tatung lcd tv. The stand by light would flash and the TV would not start up. i replaced D-2,D-3,D-5,D-48. They are fast recovery rectifier diodes. Replaced all the Electrolytic Capacitors. C-10,C-11,C-12,C-15,C-22,C-24,C-26,C-49,C-50,C-51,C-52 They are 470uf. 1000uf. 22uf. Also replaced Metal Oxide Varistors Cy-1,CY-2,CY-3,CY-5. That fixed the problem and the the cost for parts was $80.00 au. Hope this helps. Cheers
I too have run into the Tatung bad Power Supply problem. I have been looking around the web and I see that LOTS of people have been having the same problem so, in my opinion, the power supply is a poor design. In any case, since I promised to give this LCD TV to someone (before I knew it was broken), I was determined to fix it. Based on Evil_one11's comments, I changed the following components: C11, C?? (next to C11), C10, C12, C13 - all 470uF 35V, C24, C49, C??, (next to C13) - all 1000uF 6.3V, R12 - 47KOhms, C26 - 22uF 50V, C6 - 0.0047uF 1000V, C52 - 47uF 50V, D8 - fast diode, 1A 100V. After doing all this, the PS came back to life! Now, I did a lot of debugging before I replaced all these parts and I saw that the PS was being overloaded and shutting down. Once it shuts down, it locks up until a cap discharges which takes about 10-15 minutes. My opinion: one of the Caps was probably shorted out and causing the problem. I thought that perhaps the caps did not have a voltage room above (6.3 V for a 5V supply and 35V for a 24V supply and one of them may have blown during a spike in the startup. I raised the voltage of the replacement parts from 6.3V to 16V and 35V to 50V. However, I also replaced R12 because I noticed it appeared burned because it was either under designed (only 1Watt) or it was too close to the main power transistor and it overheated form the transistor's heat sink. I replaced R12 with parallel 100K 2 watt resistors which measured to be 53Kohms. I also think that it is also possible C26 may have been bad and not holding an initial charge to let the PWM controller get started. In any case, it works again so I'm happy. Good luck fixing your own supply. OH, BTW, IC1 is a System General SG6841.

Hi there, I seem to have the same problem. After three years of working properly, I moved the monitor from one location to another in the same room, and the thing has simply stopped working. I called Micro Center, and apart from charging $79 to simply look at it, the chap suggested the power supply is most likely the culprit which would be another $200. I wonder if you found a solution or simply replaced it with a new monitor altogether. I did try the CH UP on the top of the set whilst pressing the Power on button on the remote, to no avail. Your insight would be greatly appreciated [email protected]
I have a power spec 30 "TV monitor, and the problem is that the
monitor does not turn on, replace the cable and will not start,
warranty has expired and the warranty of 3 years to buy ne micro center
also expires too,the cost in micro center only to review the monitor is
$ 69.00, which is very high for me, what can I do?

Same problem....moved the tv, then wont power up...think power supply too.....anyone know where you can buy these parts?
