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.

Then i turn my rca tv on manually it wont come on


How old is the RCA TV. Is it an LCD Projection model or the older CRT (3 tubes - Green, Red and Blue) type projection model?
If LCD it could be a bad lamp or power supply. If a CRT it could be one of the Tubes is bad or again a bad power supply.

You need to replace the defective electrolytic caps on the power supply, or just replace the power supply module.

Where can I buy Dmtech AC Adaptor HASU12FB - Currys no longer stock the part


You might want to try a HASU05F. They are the same voltage, current, and connector and run cooler.

Daytek dt 3220 will not power on


OK, your Daytek 3220 is not a projection TV, but an LCD TV.

Second, I hate to say it, but you bought a piece of junk. They have excellent pictures when they're new, but after a few years capacitors in the power supply go bad. When this happens, either the controls and remote stop working, or the TV starts blanking out, or it will just die and never work again.

The solution is to go buy a new TV. The power supplies are no longer available, and even if you could get one very often the faulty power supply has damaged the main board and/or the LCD panel.

In about 5% of these cases, replacing the capacitors will get the TV to work, in about 25% it will get the TV to work, but because the main board has been damaged the TV will intermittently blank out. In another 25% the LCD panel has been damaged so once repaired you will see dark streaky patches across the display.

In the rest of the units you could have all three problems or any combination of them.

It'ds really too bad because they use a Samsung panel, and have excellent pictures when they're working.

Philips Magnavox 17MD255/17 LCD TV had AC voltage applied.


It seems your "power regulator" a small unit inside tv device has damaged due to wrong power supply. In this case usually the power capacitor burns and few other electronic components like triodes. Get the help of a electronic chip technician to replace the damaged components.

Hope it works.
