Re: proscan 40ld45q - no pic -no sound - no backlight - blue light turns off



Thanks for the wisdom - I suspected bad backlights would trigger the shutdown and lockup - it goes to the trash... Though I may scavenge the Tcon, PS and main board for sale on Ebay... maybe not even worth that effort, though...

Thanks Neil....

proscan 40ld45q

Have tried published resets with no help. (unplug for 10, push on-off for 30, push menu and vol +, etc.)

After being plugged in, red light comes on. Push power button and blue light comes on for ~five seconds then goes out. Power button does not turn the unit on a second time - have to unplug/re-plug before power button will try to start with blue light.

No sound, no picture (used flashlight test).

No bulging cap, no burn spots, no burn smells, nothing visual (cold joints/breaks/bugs).

Digital voltmeter;...

I'm Blind2Reply - new to the forum - found it while trying to fix a "non starting" Dell Inspiron. Am an EE - but that was years ago (you were all puppies back then). Heck, I remember changing tubes in B&W tvs!

I've already found some good stuff - thanks for being here to help all...
