Powering up the TV

TV will power up from cold and if turned off immediatey will turn on again. However if the TV is allowed to warm up and then switched off it will not then turn on again unless it is turned off at the mains and left to cool down. The red light on the right will blink continuously but the screen will not turn on. Set has been back for repair and the IP Board was replaced. The set was returned to me and worked OK for the first 3 days before reverting to the problem outlined above. It has been sent for repair again and they say they cannot replicate the fault. Could this be an intermitent fault that is going to be very difficult to solve. The set was only purchased in June. Thanks very much for any help.

SOURCE: Power won't turn on; red lights blinks occasionally

It sounds like a bad PSU, or a bad solder joint on one of the boards.

If the TV goes in standby, then it is in protection mode.

Ensure also that the fault is not coming from a faulty receiver box sending
bad signal, check if you get same problem on DVD with no receiver box
connected.

Try first leaving the TV power cord unplugged for some times, let say one hour or so.

The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible causes.

1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , starting the flashing light.

If you are in situation one, then the TV will reset just unplugging power cord for one or two hours,sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

If under warranty contact the manufacturer ringing the number on the user manual

If you want to repair at your own expenses, just locate any good qualified repairer.

On LCD Pay particular attention at inverter and power board, power board can be inspected looking for bulged or leaking capacitors, then tested with a multimeter. The inverter is more difficult to test , there is need to read voltages, should be done by a tech. Also the LCD controller board can cause same problem

On Plasma, test Sustain (Ysus/Zsus) / Buffer boards , cables to plasma, digital board and power board.

On Rear Projection : check lamp, lamp ballast, power board, and convergence.

On CRT TVs, check ballast , flyback transformer, CRT, Tuner, Convergence.

SOURCE: Red power indicator light is blinking

The flashing light indicates a short circuit inside the power supply circuitry. This type of repair is not a DIY without a multimeter, desoldering iron and hand soldering skills. I repair these power supplies, if you need further info write to jah2mil@hotmail.com

1. Try this - hold the menu button down for 10 seconds. TV should power up; you will have to turn off front panel buttons on menu.

2. You can also try a hard reset: Unplug TV from AC mains and remove all cables from TV. Wait about 30 minutes and replug to AC power and redo the cabling. Switch on the TV and see if it works..

3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key.

Try these first and let me know how it goes..

Just started renting house that has the Maytag Performa Electric Range and I noticed last night that the "on indicator" light is on (and still on tis morning); however, none of the burners nor the sto


The pilot indicator is powered by a contact in the thermostat or control board. It is usually not powering the oven but it could be allowing 120 volts to the element this would make the oven very warm. If you unplug the stove for a while and then plug it back in and the oven gets warm again I would have it checked. It may be drawing power.

Why does my tv shuts off soon after its turned on?


The Sceptre is a fine TV but is very sensitive to power surges.
If the unit turns off, soon after powering on, it is most likely the power supply.
Try disconnecting the power to the unit for 20 minutes and allow to completely cool down.

Re-connect the power and try the unit.

Hope it works for you

After powering on the TV, a "Dell" message pops up


The set is stuck in "Power On Self Test", aka POST.

Try unplugging the set from the wall for 15 minutes (to allow any stored internal power to bleed down), plug it in and try it again.

My tv wont turnon after being off n unplugged for 6 months what should I do. Sony kdl32l5000


First lets try the basics...
1 check the AC cord for flaws
2 try plugging the TV in another wall outlet (always use a surge-protector) then try powering the TV on again
3 plug tv into surge protector, plug into wall then find the house fuse box going too that outlet and turn it off & on once. Then try powering the TV on again.
4 it could also be the ac fuse inside the TV that blew from the TV's last usage.
If its been in the cold or in excessive thermal conditions for 6 months you could have moisture build up on the boards or warping...
hope this helps, contact me at the link below for further help...

Powering on


Bad solder connections on main power supply board, you need to get it done, turning the set on that way will eventually cause the regulator circuit to fail, solder work is a cheap fix, call a tech and start enjoying your set again instead of fighting with it :), hope this helped, BMW Rider
