Question about GE 25GT240 25" TV
The picture is very bright but i can still see color in it and from time to time it blinks with a white line in the middle of the screen then it goes back to normal i had it in my shed and i think it got wet a little bit but if any one can help me feel free to respond
With the brightness problem, first have you tried adjust the brightness on the menu. if not try to adjust it first if nothing happens set it in the middle. and if you are confident enough to fix the tv while the power is turned ON, 1.first open the back panel or back casing to expose its components turn it OFF first before opening it, 2. next if you have the schematic diagram of the (PCB) Printed Cuircuit Board find the variable resistor (VR) for brightness. if you dont have the schematics for the TV, try to find it on the PCB its a flat piece of metal that has 3 terminals and a rounded face that can be turned to increace or reduce resistance. it is mounted standing up. usually it is beside another VR for the horizontal control. it is labeled as brightness on the PCB surface. 3. when you have found it plug in and turn the TV ON tune it on the clearest channel that you can find, 4. and then using a non-metallic screw diver turn the resistance plate that would be the face of the VR first slightly turn it to the left then check the monitor for results you can place a mirror in front of the TV so you can check while adjusting the VR. just make slight turns on the VR Left to Right until picture is clear. **remember to use a non-metallic material to turn the VR to avoid elctricution. With the with white line problem or i usual call it the Stick. there is already a problem with some components on the vertical section on the PCB. it would be any of this parts the Capacitor, resistors, trancistors, and i would suggest that for you to have it checked by a technician coz it would be hard to determine which parts is faulty.
