How do I fix my Visio tv when the screen suddenly goes almost black and white?


Hi Evan
Essentially it's a computer inside a modern Flat Screen TV these days. Not a lot that the average person can do...
But... if you feel capable of opening the back....
Once you get inside and check for loose or poor connectors,
I would be looking for leaky Electrolytic Capacitors.
Usually in the power supply section.
Look for brown fluid leaks on PCB & a very slightly puffed out or bowed top on the cap. (ready to explode)
Take a picture of suspect. Take note of Polarity (black stripe) & write down uf & voltage & temp values.
eg 1000uF @ 25v
To prove you are on the right track, you can connect a similar rated Cap across (in parallel) the existing Cap.
Depending on space etc. Even by short extension wires.
Power up & see results. Fault Gone or Not?
Then...
Unsolder & Remove suspect Cap & try to replace with higher voltage rating & slightly higher uf capacity depending on space available around the components.

Good Luck

Why does my tecknika 40-920 lcd tv no longer turn on? The standby light is on but when i press the power on button/change channel button the stand by light changes to on, but the returns to standby mo


Fault with main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

My Emerson flat screen wont turn on. The standby light is on and when you turn it on the green light blinks about 6 times goes solid for a second then straight to standby again. Every 20 times or so you...


The 6 blinks are actually a error code. Go to the Emerson web site you should be able to look the code up there. Its more than likely a bad power supply. I have a friend who works on tvs and he said nine times out of ten there are popped or raised capacitors in the power supply. Hope this helps.

Issue with Samsung LE32B450. After the TV has been on for about 5 minutes, when you change channel the screen goes blank and the sound goes off. However, the TV is still on as pressing the power but


Just do a hard reset to this set and check. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. This must make it a hard reset.

While watching a dvd on the Q2035a I was using a seperate dvd player and I use a universal remote for both the dvd player and Q2035a. I began to adjust settings for the dvd player using the univ. remote....


Hello, It sounds like when you pressed the remote you inadvertently changed the scan on the ctv. This can cause the ctv ( colour tv ) to change from say ntsc to pal or similar. Even a reset button wouldnt help as it sounds like it is within the setup menu. You could try, as I have done this myself with a similar problem, disconnecting your dvd and putting it aside. Then, pressing the remote when in tv mode and watch for any change in screen flicker etc. If you have the original remote for ctv use that. If as you say, the tv goes to standby mode, you may have damaged the power supply, as the power supply will shut down to standby at any sign of a short.

Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.

Hope it may help you;
