Can be there is some problems in its power supply. Normally sound bars uses SMPS power supply rather than transformer. Its better to consult a service tech for support Because repairing an SMPS power supply is skilled work also you have to take lots of safety measures.

Dear this is fusser related problem.
1. Turn the printer off and back on to
2. Reconnect the cable between the
fuser and SMPS board.
3. Remove the fuser and re-install it.
4. Check the thermostat. If it is
defective, replace it.
5. If error persists, replace the fuser.
6. If error persists, replace the SMPS/
Two things have to be done in order to add a second optical drive.
1. Open case, remove front cover of case.
2. Remove blank from lower optical drive from front of case - remove blank (chassis part) from optical drive space.
The black insert that can be seen, removes from back on this model.
The 'steel' part on the chassis should pop out fairly easily.
Most of the time it is bad capacitors in the power supply. These will be obvious from the tops of the capacitors being bulged up. The power supply is located on the front of the chassis cluster and is the only easy to get to board. You will have to remove a shield cover to get access to it. Getting the chassis cluster out is a major job by it's self. After removing the screws from the back, you need to remove the secondary back shield. The chassis cluster is on you left side. You will need to take the mounting screws out. There are 3 on the left on the bottom side and getting to them may require a stubby phillips screw driver. There are 2 at the bottom facing the back of the set and there is one at the top facing the back of the set. next you need to remove the the black data cables from the top of the chassis at the back of the set on the left near the fan. Next you need to loosen the wire harness wire assembly thar goes to the optical block. There is also a power wire cable that goes to the fan that is mounted to the secondary back shield. This needs to be disconnected. The chassis cluster should be able to be removed by pulling lightly making sure that no wire harness gets stressed. There should be 5 or 6 screws securing the power supply shield. Once the shield is remove, it is pretty easy to remove the power supply. It is mounted on it's side and should have 5 or 6 screws holing it in place. I would replace any capacitor that has a bulging top. The values are important and should be matched accordingly. Make sure you replace the capacitors in the correct position noting the dot indicates the negative leg position. Reinstall the board, chassis, and all plug connectors before applying power and turning on.
I hope this helps,
Try to reseat the DVI cable between the chassis and optical engine. If this doesn't fix the problem, you will have to replace the optical engine. The lamp is not causing this problem. A new optical engine can be pricey. You would have to get it from Mitsubishi. $450 + $300 core charge. You do get the core charge back when you send in the bad optical engine.
If you feel that the fan does not move the all, that is the main cause of your problem. To reseat the fan, kindly turn off your laptop, remove cables & battery, press and hold power button for 8 secs, remove the screws at the back of the battery, remove the hard drive, remove the optical drive, and then reseat the fan. Then insert back the optical drive, hard drive, screws, cables and battery then turn on the laptop. IF it did not work, you need to call Samsung to replace your fan.
A WD62827 is a V30+ chassis and is a DLP format projection screen Tv, not a flat screen, am I missing something?? For the symptoms you're describing with a WD62827 remove and reseat the DVI cable between the chassis and optical engine. If removing and reseating the DVI cable does not resolve the issue you may need to replace the Optical Engine part # 938P019020
BTW the current software version for this unit is 7.04.1F if you have anything less you might think about updating the software also..
Hope this helps!
