Take the tv off the stand, lay it somewhere securely, take the back cover off , plug it in the mains, get a voltmeter and check to see if the mains power reaches the power board. If it does then try to start it and test the power source to see what's not working: the mains rectifier, the filtering capacitors,the power transistors or the transformer. If all get power but the outputs are dead then the regulator is defective - you will have to test it to find out why: start by checking to see if it gets powered and if the oscillator is working
If you don't know how to do all that then it's time to call a repairman.

What does the light flashing on a sunbeam electric blamket controller mean and why wont the blanket heat up


The flashing red light is designed to notify you in the event that
a problem has been discovered by flashing the light on the base unit.

Before resetting the unit. First, check the blanket/mattress
pad for visual damage.
If no visual damage is found, unplug the system from wall outlet.
Check that the base unit is well connected to the module. Plug the power cord into the wall outlet. Set the base unit to "On." If the system still does not operate after two or three times trying to reset, disconnect the power cord and get it checked out by a specialist!

Buttons on TV suddenly not responsive


If they are actual buttons check to see if one is stuck. Listen for a click on each button while it is turned off so you can hear it and feel it. Another possibility could be when you moved it around somehow the internal cable that connects the buttons to a connector has slipped out or just has a bad connection. Would require you to take the bezel off to see if the internal connections are ok. Not sure what else to suggest. At least the remote works.

Onkyo TX-sr605 will not turn on.


did the voltage selector on the back of the unit possibly get moved to wrong setting? You could also try switching it back & forth a few times (unplugged first of course) to see if maybe the switch needs "cleaning"

Monte Carlo ceiling fan and light not working


Even a brief power outage can cause amnesia in the receiver. You can try disconnecting power at the source and spending a few minutes removing the battery from the wall-mounted remote and pressing all buttons to eliminate the 'stuck button' problem. Reinstall the remote battery and reconnect main power to the unit. Test operation.
Lastly, there always is the possibility that some gremlin changed your original control setup.

My lg lfd790 would not turn off so i unplugged it now i can't get it to come back on w/ power button on the unit or power on the remote.......happened once before but worked for a lil while now nothing......


Remove wallpower. Hold Power button 30 seconds. Reconnect wallpower. Turn on. If no success, remove wallpower 30 seconds, then hold power button while attaching wallpower. If no response, or unit fixes to AUX, requires service to reprogram the hardware. Send to Alabama 800 243000

Dmr-es30v combi-vcr/dvd


Due to a design error there are 2 defective capacitors in this unit :

C1209 680µF 10volt 105°C - always fails being primarily responsible for unit's failure.
C1204 1500µF 16volt 105°C - also known to fail with great frequency.
If you have some basic electronic experience (or know someone who has). Replace capacitors C1209 and C1204 with new ones rated at 35 or 50 volts. You can get these from RS Components for around £3.00 (C1209 is hidden from view as it's located underneath the DVD drive mounting bracket. For this reason, the DVD drive must first be removed before it can be replaced). The unit should be unplugged until you can repair it. There is no alternative way round the problem, but once repaired it will work perfectly.

Try unplugging it from the wall for a minute, then see if it works. If not, it's probably a power supply problem inside the unit.

Hope that helps
