Question about Projection Televisions

Samsung LNT4665FX 46in flat screen LCD power supply cycles on/off, with audible que. Blue light at bottom of screen remains lit, but screen remains black. Does not respond to manual on/off or remote control on/off. Disconnected from power source for approx. 10 mins. Power supply energizes and blue light comes without aid of manual on/off switch and TV begins to cycle on/off again as before.

Check out the fixYa solution for the Samsung LNS4051D- it sounds like the same problem. Defective capacitors. You may need different part though.  We just fixed my mom's LNS4051D with that problem. I have the LNT4665 and although it hasn't failed yet, I am tempted to get some capacitors just in case.

Sounds like your power supply capacitors have failed. Google for Z1234TV and see if you can locate a power supply capacitor repair kit for your model.

hi,
Check the lamp colling fan is it working or not. Also check the connection on the lamp holder is proper or not, possibility of connector burning . then, you have to check the lamp power supply. check the fuse in it. if all these are ok then you have to change the lamp power supply.
ok

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.

You have a bad blue LCD in the light engine. Replacement of the light engine is the only fix and it usually will continue to get worse over time
