    It's wonderful to know that there may actually be a solution! The only problem remaining is that I have NO idea what a flyback is, what a flyback looks like, where the flyback is located, what a flyback does, or how I would tell if the flyback needed replacing. Can you give me a little more help on this?

    Thank you so much for your time. Be safe and take care of you and yours!

Sounds like the flyback is arching. i would suggest looking the flyback over for signs of arching. You may need to replace the flyback. If you need to know where to get a replacement let me know and I will post a link along with the correct part to order.

I have a akai 61 inch dlp tv, my son turned it off went back 1 hour later tv would not come on with remote or by push button on front, checked to make sure power was in cord to back of tv, any ideas what...


I'm assuming that no lights are blinking on the front of the tv and the bulb is in god working order - it has been replaced recently. In that case the tv will have to be opened and the voltages on the power source tested, starting with the ones on the main switching transistor, followed by the ones on the output rails - a good voltmeter will have to be used. If all are there then check the voltage going to the

The first place to start is the outlet and check to be sure it has power. The next is to check / replace the main internal (to the tv) fuse - it's a 5A 250V GMA fuse (google image of GMA fuse). To find the fuse, unplug the set and remove the back cover of the TV - follow the power cord to where it enters - the fuse is located to the right and slightly ahead of where the power cord is attached to the board.

Magnavox mrv640-accidentally turned on progressive scan


Had exactly the same problem. You need to reset the DVD recorder to it's default setting. The default is "interlaced".

From the users manual.........

Switching the DVD Recorder
1
Disconnect the recorder's power cord.
2 Hold down the FF button (arrow pointing left) the front of the DVD Recorder while
reconnecting the power cord. 'PRO' (progressive scan) will appear
on the display.
3 If you want to switch back, repeat steps 1 and 2 . 'PRO'
(progressive scan) will disappear from the display. The DVD
Recorder is switched to 'Interlaced.'

The manual is at:

See page 12


It worked for me.

No picture, no sound, power light steady green


First: Check the power outlet. Check it with a good lamp so you know you are getting power to the set.
Secondly: Check the power cord. Wiggle it around the molded ends to make sure it is not open inside the molded portion of the plugs.

Thirdly: If you know for sure the set is getting power and still no indication at all (you should be getting some little light on the front panel; standby indication) then there may be a fuse on the back panel or just inside the back cover (you will have to remove it; after unplugging the power cord) that needs replaced.

Fourthly: After all these checks if you are getting nothing, you may have some failure inside that is very serious. Normally we do not recommend serious repairs to a set over 4 years of age. This is because the set is likely to develop some other problem soon after the repair is made; further, the repairs are getting more expensive day by day while the price of new sets is coming down dramatically. Lastly, the new sets have better picture, longer lasting circuits and better features.

Hope this is a good solution for you.

thanks for your questions.

Power issue, clicking noise, turns off


The clicking is the power on relay closing and opening. This happens because the TV has several built in safety systems that will detect and over voltage and over current load situation.The power supply starts up for an instant, senses and overload of either or both kinds and then the safety switches trigger a cutoff. When this happens the power supply will not start up again because another circuit called a latch keeps it disabled. By unplugging the AC cord and trying to start it again releases the latch until the failure triggers it again.
On these TVs the power supply is rarely the cause of the shutdown. Something further down inside the TV has failed. Replacing just the power supply will not fix the problem. The most common reason there would be an overload would be in the high voltage circuit that lights up the 3 CRTs, next would be the coils around the CRTs that bend the beams to make the picture. This is normal circuit aging and wearing out. Unless you are very skilled with trouble shooting TVs I would recommend having a service center look at it. An authorized JVC shop would be your best choice because they will have access to the manuals and bulletins and have probably had other similar JVC units thru their shops.

Power supply for dmtech wt20xt lcd tv


I have DMtech 20" with intergrated DVD and had the same problem- blue light lit on power switch but no response on power up.
I noticed that when the power cord was unplugged from the back of the TV the green LED on the power supply would brighten and consequently dim when plugged back in. Sometimes the blue light on the power switch would strobe very quickly but you had to look carfully for this.
I repeatedly unplugged the DIN type power plug from the back of the TV untill the green light on the power supply stayed a constant bright and there was no strobing on the blue light on the front of the TV, when I powered the TV on at this point the button worked again and the tv powered up with the silly tune then life in the screen. I did have to do this a good few times (I'm tenacious) but it did work!!!!!
Hope this helps someone else, cheers.
