SOURCE: When I turn on tv, green light comes on and there

This Proscan 19LA25Q has no relay to make any clicking sound that I can think off. The common problem with this model is the fail backlight inverter board. Did you see the screen flashes on for a second? You should also check the output voltage of the AC adapter, it should be 12vdc with load. Check the surface mounted fuse on the inverter board (this board is really hard to find).

SOURCE: I have a 47" Proscan

Right now the standby 5vdc power supply for the processor on the main board is working (the standby power supply and the processor are running 24/7, even when the TV is OFF) but nothing else, and since you cannot even turn on the TV at the TV control panel it may mean that the main board is not functioning.
I would inspect the power supply module first though just to make sure it does not have any bad caps, burnt parts since bad DC can make the TV to have strange symptom.
Please read my guides first to understand more.

Monitor won't turn on after a few hours of being shut off


If it EVER works, then the problem is not a failed part, but a weak part. The most likely component type to give you such problems are capacitors. But very few repair techs know how to find such problems, and even fewer have the equipment needed to find the bad one(s) in-circuit. The failure mode is high ESR (ESR means Equivalent Series Resistance). The lower the ESR, the better. Capacitors with high ESR cannot stabilize circuits which demand high pulse currents, such as in switch mode power supplies.

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

I just got an LG TROMM DIE2512W dryer. I have a power supply cord with three cables (green, black and white) good for 120v.15amp. The green cable is my ground. I connected the black cable from the power...


Hi,
If you have a red wire then the dryer is a 240v dryer and needs a 240v 30 amp circuit...

Here is the manual for your dryer and it shows the hook up you need on page 17...or part 5 of the manual...

My 1501 Dell Inspiron turns on but I have a blank black screen. The only light that shows is the power light on the upper right side of the laptop.


Power getting to the laptop. Try first to see if this will give a screen image on an external monitor, listen for the sound of the cpu fan, hard drive and DVD rom drives clicking, see if the DVD rom drive will open if pressed.

Then remove battery and AC adaptor, press the power button for 30 secs, refit mains only and try this on mains supply (no battery)

If this fails to boot, check the light on the ac adaptor is a steady green, flashing green indicates power is not fully reaching the laptop (motherboard problems)

If it is steady and the LED power light on the laptop is steady, suspect the DC jack socket. If this feels loose or sloppy, it will need replacing, depending on the type fitted, it may be soldered onto the board, or a wired connector, which sometimes goes bad.

After that, I'd suggest that a capacitor has gone on the actual motherboard and you will need to strip the laptop to check it.

Screen black. Power light on unit flashes red slowly. Power light on switching adaptor power supply flashed green slowly.


Sounds like the battery might be low which would cause the red flashing light and dark screen. Let it charge for a little bit then try turning it on again. If it still does it with the power supply plugged in, make sure there isn't a lens cover on it, and switch modes or try getting into the menu to see if you can get anything to come up. If that still doesn't work then it sounds like there might be a problem with the camera.
