SOURCE: Power LED blinks red

it is a bad fan. it also could be a power supply. Quite often the real problem is dirt clogging up the fan(s) to the point that they need to be replaced. Operation of the set in a dirty environment is not a good idea

SOURCE: jvc tv

when both the blue light and red light are blinking it means 1 of 3 things. 1. lamp replacement. This often works everytime for the repair. TIP!!! DO NOT USE ANY OTHER LAMPS OTHER THAN JVC AUTHENTIC LAMPS. ANY OTHERS AND YOU RISK DAMAGING YOUR TV FURTHER. 2. the fans are not working properly or need to be replaced. They need to be cleaned every so often and they will stop working from burn-out if not done so. This repair will cost you less than 100 dollars. 3. The ballasts are defective and need to be replaced. The ballasts themselves run about 150 dollars. I tell you I have fixed this TV more times than I care to count, not to mention the number of lamps I have gone through. The guy at the TV repair place now knows me by name when i come to buy lamps. :(

SOURCE: kdf-50a11e blink 3 time on red

Three flashes indicates either the lamp is not seated correctly or the lamp door is not on properly. I bet its the later of the 2 as THE most common issue is the lamp door has warped because of excess heat building up in the lamp cage. If this is the case follow the link I am providing as you are in luck as Sony is paying for those repairs. Please take a moment to rate my answer...Thanks

After lightning MW12C1E replaced burned fuse on power circuit unit satrt then flashing green LED then stop how to read error code ?


If you had a major surge then chances are the entire outdoor PCB and possibly the inverter transformer need to be replaced. I'm not as familiar with the Friedrichs but most mini-splits use flash code errors on both the outdoor and indoor units, occasionally with the common codes printed on one of the outdoor service panels, usually only in the service manual (supplied to authorized dealers and sometimes available from manufacturers websites).

Out door is not working


Check for communication from indoor to out door.Check power in out door unit. If not, check the following.
Keep cool mode and temp setting minimum 3 degree less than room temp.
Check indoor unit return air sensor. Disconnect sensor from PCB and measure resistance. 8 kOhm at 30C and 13 kOhm at 20C if not replace air sensor

Check Indoor Pipe Sensor Disconnect from PCB and measure resistance. Pipe sensor = 5kOhm at 25C. If not replace pipe sensor.
Thanks and hope helpful?

Wash out your outside coil and monitor the outside fan. sounds like a lockout due to dirty condenser or intermittent motor operation. Could mean condencer air problem.
