If you hear a sqealing or buzzing sound when you plug in the TV, the most likely cause is a shortedHorizontal Output Transistor (Q405) , due to a dry10uf/25v electolytiic capacitor on secondary side of Horizontal Output Transformer. If this is the cause, there will be tell-tale scorch marks in the vicinity of the capacitor. If you do not hear any noise, then the likely result is a bad Shottkey diode, of which there are quite a few possibilities In any event, DO NOT ATTEMPT TO REPAIR ANY TELEVISION YOURSELF FOR DANGER OF ELECTRICAL SHOCK! FIGURE THAT ON AVERAGE, FOR EVERY INCH DIAGONAL OF TV, YOU WILL HAVE ABOUT 1,000 VOLTS TO CONTEND WITH. THAT MEANS THAT A 27" TV SET WILL HAVE ABOUT 27,000 VOLTS!

The outlet is still OK, otherwise you need to open it up and check the main AC fuse in the power supply module, it should be labeled with F1 on the board, it should be close to where the power cord is connected to. The surge protection devices may have blown also.
If you are going to DIY and have proper tools, electronics knowledge, and know safety precaution then please read on:

Or just make sure to use caps with low ESR, 105c, high ripple current, long life rating such as PANASONIC FM or FC series.

Ilo tv will not turn on. I was able to unplug the tv, plug it back in and then it would turn on. Now, nothing works.

is there power came from your outlet if yes then check your power filter fuse if OK then check your audio board because it act as output and crossover power that is depend only if you have red light on,also check your power supply board for blown capacitors. also get another opinion good luck.

If the "Chopper" transistor repeatedly "Blows" it is usually because the LOPTy (Line Output Transformer) is faulty, usually a short. OR a shorted Diode or Capacitor, in the driver or output.

My ilo tv will not turn on by the remot or power button

Remove back cover. Check to see if the fuse is blown. If not, check power from power supply to main control circuit to see if there is power. If not, the power supply is probably bad.

No power

I assume you unplugged the unit for several minutes and tried plugging it back in to reset it. Is the outlet ok? Did you try plugging something else into the same outlet and it worked?

If the cord is ok and the fuse isn't blown and the VCR is completely dead, I would say that you have a problem in the power supply section. This could be a bad transformer, rectifier or regulator module. Unfortunately you'll need to take it to be serviced.

Please let me know if I can be of further assistance to you.
