    Hello

    The problem with my TV is that I can literally hear the TV trying to turn on (some clicking noise inside the TV), but after 3 attempts it just stops. After trying several times in a row the TV will eventually turn on and function normally. Once the TV is on for sometime, if I turn it off it can turn back on without problem. Also, I've noticed that the TV can turn on much more easily if it is warm inside the house; it takes much, MUCH longer to turn on if it is cold inside the house.

    Please help!

It sounds like your TV may have one or even several defective solder connections that need time to warm up before the TV will work as normal. The connections could be on any one of the circuit boards. For starters check out the convergence board with a X10 magnifier and pay close attention the the connections on the pins of the amp modules on the board.

If you have no electronics experience or experience with power, then I recommend that you get someone who does to check it out for you

Ciao marco,

The clicking noise is a device called safety protection switch that keeps turning off the TV because an error has been detected.

When a problem, such as a wrong voltage, a short, a defective IC or a bad component is detected, them main chip in your tv, familiarly called the jungle chip, send the unit in what is called protected mode.

In this situation a switch will keep turning TV off to prevent more damage, that is the clicking noise that you hear.

Try unplugging the TV from power for one hour or two, this will drain power completely and reset TV.

If it does not work, then the TV must be inspected following the troubleshooting diagrams from the service manual.

To do it yourself you need experience in testing electronics, some test requires working with live power. If you decide to DIY , get first the service manual.

If you need to call a technician use the phone number printed on the user manual.

You can get service manual and parts here.

Spero che questo possa essere d'aiuto.

Regards

My Samsung tv model CS - 29M20MH switch onto standby mode with led flashing several times then switch off - no screen coming on


From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

your problem lie in the electron gun at the back of the CRT. most likely is their is a faulty transistor or resistor that has been devalued/worn out and has to be replaced.
There should be 3 main transistors for the 3 colors - red , green and blue. So most likely the green and blue are acting up so you only have the red that is producing color leaving your screen with a red hue like appearance.
It would be wise to replace the CRT board if you plan on keep using this crt monitor for a longer period as soon their parts will be unavailable to the phasing out of crt monitors.
Good luck and thanx for using Fixya.

I have connected my PC to TV via S-video. Pc works fine, but tv displays just the background of my PC screen. Audio works fine. Please help. Thanks


So what exactly is wrong? It seems like you have dual screen enabled. Try mousing beyond the edge of you PC screen, the cursor may move onto the TV. If you don't want dual screen, there's an option for clone display instead.

I want to use Trutech 19" tv as computer monitor. Scrreen starts to set up and then get error message "Unsupported Mode." Is their a simple fix for this?


Hello Fayeburns,

Yes, there is a simple fix for it.

The reason why your TV is showing Unsupported Mode is because of the display resolution of your

graphics card, which is higher than what the TV can handle.
What you can try is, when your system is powered up, just go to your display settings, then

reduce the systems display resolution to--preferably 800x600 or 1024x768, then go to where you

normally select the output, and select 'Output to external monitor"...this should send the signal

input to the monitor.

In case it still doesn't work, just try and update your graphics card driver to the latest one and try

the same process again.
Most Laptop graphics display resolution are generally very powerful as compared to what the TVs

can handle.
Try this out and let me know how it goes.

Hope this helps.
Goodluck and thank you for using Fixya!

Exactly as the old TV's. There is three tubes producing the picture and the technology is just the same. If you cannot find your instruction booklet, log onto Sony's web site and download it.
Hope this helps.

How can i make the laptop screen show through my tv


Hello.
Simply hooking up is not enough. What type of cable are you using? HDMI? analog VGA? DVI? S-Video?
* You should also use [Fn] button in combination with [F5], [F8] or another button that shows monitor sign as well (CRT/LCD if it's in written form). Possibly by pressing several times in order to achieve results.
* In some graphical cards (usually in Intel Extreme Graphics) you should locate icon on systray (near the clock) and right click on it, then choose (Graphic Options) -> Ouput to -> Intel (R) Dual Display Clone -> Monitor + Notebook (if you are using VGA cable)

A solution in graphical details can be found here:

Still Not working. no output on tv.


Open the ATI software, go to "set up my display configuration" and from there you should have an option to make the TV mirror your screen exactly. If I misunderstood you and you're attempting to do something different, all the options you need to configure your display should be right within the ATI software.
