Question about Akai PT46DL10 46" HDTV-Ready Television

1 Answer

Flashing white lights on screen

About every 30-45 seconds it looks like flashes of white light appear on the screen. The lights are not steady and disappear right away and are on random spots on the TV. If I turn the TV off it doesn't happen for a while but does eventually return. This all depends on how long I keep the TV off.

Tv is stuck on standby. The standby light (red) is steady and when I press the STANDBY button, nothing happens. no response or flashing light.


If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Check the cables, connectors and connections.
Take it to a repair shop.

Commercial have lights flashing whilst in the air. why?


It's not just commercial aircraft. In the US (and most of the world), all aircraft will have those lights during night operations. [There are a few exceptions, such as aircraft without electrical systems - and yes, there are such things.]

The steady lights on the wings are called "position lights" (also called "navigation lights" or "anti-collision lights" or similar names). The one on the left wing tip is steady red (that's the left side, as you are sitting IN the aircraft). The one on the right side wing tip is green. There will normally also be a white tail position light (steady) on the tail.

In addition, most aircraft have strobe lights. A white light on each wingtip is common, as is a red strobe light on the tail or belly.

The purpose of the lights is two-fold (well, actually, the only REAL purpose is to help avoid collisions!). First, the strobe lights are there primarily to catch your attention. A flashing light is much easier to spot than a fixed light. The other lights are there to indicate direction. At night, it is very hard to quickly determine the direction of travel (left to right, away vs. straight at you, etc.). But by determining which colors are visible, you can quickly determine the orientation of the aircraft. Whelen (a primary producer of aircraft lighting) has a web page with nice diagrams: http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=7&ved=0CDkQFjAG&url=http%3A%2F%2Fwww.whelen.com%2Fpb%2FAviation%2FSystem%2520Requirements%2FAnit-Collision%2520Systems.pdf&ei=v1wDVOv8E8nzgwSyroGABQ&usg=AFQjCNHZf7nhnmC_Mj0wp44-uLXBFB8gJA&sig2=h61HBbMEeD6fZA6vF9Czyw&bvm=bv.74115972,d.eXY

Hope that helps. [And the short answer to your question is - because one midair collision can ruin your whole day (or night)!]

How to flash a generator


Get two short extension cords and cut the FEMALE end off each one. Strip back the insulation on that end. Connect the two green wires to each other, and connect the two white wires to each other.

Connect one black wire to a light switch, and connect the other black wire to a 20W appliance-type incandescent light bulb. Also run one short black wire (from a cut-off end) from the second terminal on the light bulb to the second terminal on the switch, like so:

plug -- black -- switch -- black -- bulb -- black -- plug
plug -- white ----------------------------------- white -- plug
plug -- green ---------------------------------- green -- plug

Turn the switch to the OFF position.
Start the generator. Plug one plug from your new rig into an outlet on the generator. Plug the other plug from your new rig into a wall outlet supplying 120V. With the generator running, turn the switch to the ON position.

The bulb should flash for a short while, then become steady. When it's steady, that side of the generator is flashed. Repeat for the other side of the generator if it makes 240V.

Pictures are blur


Hi,

Your pictures are blurry because the camera did not focus properly on the subject.

First, turn on the camera in any picture taking mode (or video mode), then look at the screen or viewfinder. There should be four white corners in the center of the camera display. This is your targeting area.
---------------------------------------------------------------------------------------
1. Aim the camera at your subject so this center area is directly on it.

2. Press the shutter button lightly, not all the way down. Wait for a second or two WITHOUT RELEASING YOUR FINGER. If the white corners turn green, keep the finger on the button and press it all the way.

(Once the screen flashes black, a picture is taken and you can release the finger).
----------------------------------------------------------------------------------------
If the targeting area turns red and blinks, then the camera has not focused. You can to try to focus again by following step 1 and 2. If a picture is taken when the targeting area is red, then the picture will be blurry.

If there is no targeting area, then you can still focus by aiming the camera at your subject. Now follow step 2. A green box will appear on the subject, then a sharp picture can be taken.
-----------------------------------------------------------------------------------------
The red arrow that flashes means that the pictures or videos are being written onto the memory card.

Also, try to be steady when taking pictures, because slight hand movement can cause blurry images too.

Page 25 in the DMC-FZ7's english manual will also explain how to focus.
