Hi!!

Check breaker box, if ON, check wiring to make sure power is getting into unit. If power is coming in, check that transformer in unit is geting juice, just feel it, it should be warm, if cold, replace it. If You don't feel comfortable touching transformer, UNPLUG unit and just check ohms between the two input wires you should have a reading, then, check between the two ouput wires should have a reading, if no reading on either one, replace trasformer. 90% of he time the problem lays around this area.

BE CAREFUL WHEN WORKING WITH LIVE CIRCUITS.

My samsung DVR 4 channel will not turn on. There is a red light in the rear inside, but the unit itself will not come on. I noticed a beeping sound coming from the unit every 10 minutes or so.


Will it show any lights on the front display at all? If there are no front light, then there may be a power problem, try plugging the unit into another socket and if the red light inside the unit returns and wont display anything else the I suspect that it may be a burnt out power pack, which will need to be replaced by a service technician due to the high voltages with power sources.
Hope this has helped :D
Any more questions please just ask!

It keeps blinking protetor


The protector circuit protects your amplifier from shorted speakers . One of your speakers , or more speakers are shorted out . To figure it out easily follow these instructions . Turn the unit off . Now unplug all of the speaker wire connections from the back of the unit . Turn the unit on . Make sure the volume is turned all the way down . The protector light should not light up . If it does , the problem is inside the unit itself and we'll have to be repaired at the shop . If the protector light is off than continue on as follows . Connect the speakers one at a time to the unit . Each time you connect a speaker , turn the volume control up and back down making sure the protector light does not come on . When you connect the bad speaker , the protection light should come on . Whichever speaker makes the lights come on when connected is the bad speaker and should be replaced .

Indoor unit does not function -outdoor unit works


These units have circuit boards inside that have lights on them. These lights come on and tell you what the problem is. I have had 4 units do the same thing that yours is doing. The result has been that the compressor has gone bad. You have to get access to the control board to see the lights. There will either be one inside the inside unit or one inside the outside unit depending on exact manufacturer date.
Good luck and hope this helps.

Operation light and timer light blink 5 times?


I don't know if this is the proper technical solution or not but my unit was having the same issue. I cleaned it checked fuses made sure the cover was properly in place and nothing worked. As a final thought I went to the home fuse panel and tripped the breaker for the unit, waited about 30 seconds and turned it back on. I did this with the unit set to off. When I came back and turned it on, it is working properly with the operation light solid red.

No cooling after power out, indicator lights pattern not in manual


The Mitsubishi units have to be reset by turning off the indoor units by switching the remote or thermostat to off. Then turn off the breaker to the outside unit(s). After 30 seconds,turn on the breaker and then you can turn on the remote for cool. If no lights come on on the inside units, most likely you have blown a fuse soldered on the main PC board. At this point, call your technician. A goos tech will be able to wire in an in-line fuse holder so if it should happen again, you can easily replace the fuse. If you do see a light or two come on at the indoor unit but the outdoor unit does not start after 3 or 4 minutes, sounds like you will need to call a technician. Most likely you have a blown fuse on the main PC board of the outside unit. It is not an easy one to replace. Good Luck!
