Re: TV WON'T COME ON
If the fuses are good and the on indicator lights you could have a short in the power supply, the high voltage section or just about any part of the circuitry. The most common problem is the high voltage. If you know TV safety and how to check transistors, unplug the unit and check the horizontal output transistor. If it is shorted replace the transistor, flyback and HV divider. If this does not solve the problem you will probably need a repair tech as this symptom could be a short anywhere in the unit. Good luck and remember to be safe.

if you have guaranteed power to the set it is likely you are having an issue with the power board. You will have to unplug it and remove the back of the set. Then check the power board for any blown fuses or other components. You do want to post pictures of your boards with your question so we can try and assist you further with that. For that use this guide The attached image should show the fuse on your power board. Check for continuity and see if you get power to that, once it is checked. Unplug your set to check it for continuity. Then plug it in and use your meter to check for power.
Possibly you've had a power cut & a fuse associated with the TV has blown. Have you checked the fuse in the TV plug? If that's ok then probably a fuse internally in the TV has blown or something more serious has blown in the power supply
Try unplugging the TV.. After you plug it back in it may be OK. I had a similar problem were I could not turn on the TV (JVC). The owners manual specified in the troubleshooting section to unplug for 1/2 hour. I left it unplugged overnight and the next day plugged it in and it was fine.
total dead usually means the fuse---unplug the set for safety and remove back cover---follow power cord just inside and you will find the fuse in a snap in holder--check to see if bad.............if good let me know and I will try to assist you.
Your tv set suffered short circuit problem in the power supply area since it fails to turn on. Try to open the cover of the tv and check for the damaged parts like a busted fuse or shorted power transistor and replace it.
power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.
