Well sounds like a Horizontal PSU problem... a component is or has gone faulty.. causing incorrect voltages to be generated.. thus the problem.. shouldn't be too hard to fix..It may be also an IC.. any TV repairman worth his salt should have no probs fixing it fairly easily.

After connecting the Wii to LG TV (55 inch LD520C) the LG TV will not stay on! it blinks an image 3 times (maybe 10 seconds total), then turns OFF!! we disconnected the Wii, but the LG TV still turn

How old is the TV? LG warranties its TV's for 1 year unless you have a extended warranty from where you got it which is stupid not to have. Was the TV exposed to moisture or bugs? I've never heard of a Wii corrupting a TV. If no warranty then it could be a power supply or the main board. Find a repair service that gives free estimates, find out what needs to be fixed then go online and find the replacement and are good sources for parts. Replacing parts is easy, a screwdriver for screws and unplug cables by hand. If it's a power supply wait 1 hour before removing because the capacitors can still hold a charge and to be safe hold it by the edges of the board and put it on a non conductive surface like glass. If it's the Main board just switch it butsometimes after LG and Samsung main boards are replaced Solarization can happen. If it does just google it and you will find a easy fix. Good Luck

Lg 52 in lcd turns off then back on when your

The problem lies either in the power supply or the main board. But most probably it lies in the main board. These boards communicate in switching on the television sequentially. The power supply sends a signal to the main board when AC power is supplied and puts the television on stand-by. When the TV is turned on, the main board sends a switched command to the power supply to deliver it's output for audio and video processing. At the same time it turns on a supply voltage for the backlights.

What probably happened is, the signal sent by the main board to the power supply is being switched on intermittently and causing the turning on and off of your television.
  1. Remove the back cover of the television to check the power supply and the main board. The power supply is the one with transformers on it and located at the center while the main board is the one where inputs are being connected to and located at the lower right back of the television.
  2. Check the power supply for any swollen capacitor.
  3. Turn on the television and check if the LED on the main board flashes as the TV turns on and off.
Please inform me what will you find above and if you can do electronic repairs. Just tell me if you need guidance in replacing parts for your TV.

My Acer X263W will power off during the reboot of my PC. I cannot power it back on unless I switch off both my pc and monitor for at least 2 minute. How can I make my X263w power on again without turn off...

Your PC monitor may be a CVT type. Anythingwill switch off when a monitor powers on. Its initial kick off current is very heavy and thus sucks in all the current from neighboring devices (your Acer X263W included) and renders them powerless. The only way out is to put the PC with its monitor and the Acer on different power sources (sockets) so that they do not interfere with each other's power requirements.

We have many problems with loose or poorly seated cables and connectors on these units. Pull the back and reseat all the internal cables, especially the LVDS cable to the LCD control bd. If this does not correct the problem the main cause is a bad LCD control bd. or possible a defective main bd.

Samsung 46" LCD TV stops responding

Ok, There are well three boards in this set that would influence such a behavior. The culprit is the Key Pad Board. It has what is called a leaky switch. This then locks up the Microprocessor. This will result in the set operating like a ghost has the remote.

best regards
