Common problems with tv sets

phone on another extension off hook
line has timed out
or
if NBN - try powering down nbn modem device and wait 20 seconds and power back up and wait five minutes.

sound would be bur bur bur .

Make sure the fan is working and that the vent and/ or fan are not clogged with lint . Overheating is one of the most common problems with TV sets turning off and on.
Hope this helps.

Sounds like a blown capacitor on your board to me. Its a common problem in Samsung TV's and is typically an easy fix, but I think in the LG's its a bit more expense and not as easy as swapping out a Capacitor. I think the main board may have to be replaced there. What actually happens is the capacitor bursts at the top and oozes liquid that solidifies, its caused when the capacitor that is used is underrated for the application (basically some engineer's solution to making us have to buy a new tv in 3-4 years, a slightly underrated capacitor will have a shelf life of use, kind of like a timer, they all do it belive me) eventually the set will not rendure any picture at all and the board will have to be replaced.

Sir this problem is commonly caused by bulging capacitor or loosed connection, if you remove the back cover be sure to unplug the unit. Bulging capacitor is producing a low and unfiltered DC supply, one of the sign is the clicking noise you hear came from the relay. Or try to tap the side of your tv and observe if the tv will react.

This a bad capacitor
this is the loosed or dry joint it is much better if you use a magnifying glass to determine the loosed or dry solder. Good day and best regards.

All projection TV sets have two very common problems. One is convergence ( 3D/Warped video or dead set) the other is CRT fluid ( Dull Video). Here are more details and solutions for both.

Common Problem #1) Convergence has gone out

Projection TV sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the video to look normal. When its out of alignment the video will look 3D, wavy, distorted, etc. In some cases the TV will also not show any video. Most of the time you just need to adjust your convergence in the TV menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

This is a very common failure on these projection sets and a fairly simple DIY fix. All projection sets including Samsung, RCA, Sony, Philip Magnavox, Panasonic, Pioneer, Akai, GE, JVC, Toshiba, and others at some point will have the same problem.

Common Symptoms include....

• Screen looks 3D
• Colors don't line up
• One or more colors can't be adjusted when using the convergence menu.
• Screen is bowed or warped.
• TV shuts off after powering on. Power light will blink. TV may also make a chirping noise.

Here are some pics of convergence problems.






Common Problem #2) CRT Fluid is Cloudy

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images.

Induced noise - running signal wire too close to electrical cables.

Faulty/damaged Input reciever (jack) on subwoofer - test by isolating PC, and attaching iPod or other device to check for noise instead.

If the noise is not present when using the isolated source, your sound card output jack is bad, or the soundcard itself.

This is a power source problem and it will need to be fixed by a pro! This is a very common problem with the Sylvania sets! (cost to fix 250.00-350.00)

does the sound come from the speakers are from the back of the set. there is a small number of cases where the is oscilation in a coil.. the way we counter this at the shop is we dampen the coil with some silicon, not sure this problem you have. ll007 is the number on the coil.careful this television generates high voltage and retains this even unplug

Projection sets have two very common problems.

The first common problem is convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

Here are a couple of the most common reasons for your problem:

Make sure you have selected the right input source on the DAV-HDX275 that your TV station source (cable, satellite, direct TV or whatever you get TV stations from) is connected to on the DAV-HDX275.

Also make sure that if you are using a digital input (HDMI, optical, or coaxial) from the TV station source, that the DAV-HDX275 in set for a digital input and on the right source.

If you are using an analog source (red and white RCA jacks) for the TV stations , make sure you do not have the digital input activated for that source on the DAV-HD275. You need to select the analog option.

You must also be sure that you have a cable, whether it is analog or digital, connected from the cable box to the DAV-HD275.

I hope this was helpful to you, it is always very important to double check all the connections and make sure the stereo is set to the right type of input (digital or analog).
