    this is a lcd tv not a crt

    no help from fixya members, but managed to repair myself, fault is on inverter board in the area of the i.c. This chip shuts down if faulty txfmr or light tube, if pin 10 goes above 3.5volts due to fault you can do 1 of 3, 1 = replace inverter board, 2 = repair board down to component level, 3 = cheat like me, solder a led to pin 10 and ground on the inverter board.

    If you try 3 do it on you own back as i take no responsiblity if goes wrong.

    not sure how long this will last.

Display problem on the main board .check it out

Sounds like a common problem where the Horizontal Output Transistor shorts due to heat, loading by a partially shorted flyback or yoke or old dried heat sink compound. If the HOT is ok then there is probably a short in another component. This can be determined in most cases by isolating each module one at a time. In other words disconnect the audio circuit and try, disconnect each crt separately, etc. If no shorts are determined check the power supply for proper output voltages. All this would need to be done by a tech or someone familiar with the process. Repair cost should not be that much compared to the cost of a new set.

feel free 4 further assistance n keep sending more question n comments or doubts that arise in ur mind regarding this to me.rate the solution as fixya if it helps u understand n solve ur problem

My mum in law aged 94 has now got a Logik l19dvdb20 (had to becuase of digital change over) its her only view to the world. I have tried a few easy to use so called universal controllers but they dont work...


Unfortunately there is nothing in the menus to allow for the requests. Maybe a way around it is to write down, on a piece of white card, which button to press "parrot fashion" to get the desired result that she requires.
Hope that helps.

Switch TV on then a blank red screen appear then a green and then a blue which then just repeats that sequence of colours every second. The remote control packed up working some month before. - 2 year old...


turn TV on, let the Tv cycle through the three colours, then using the remote press the menu button followed by the standby button. press standby button again and it all comes up working.

We have this problem too! So far turning off the set from the button on the TV and leaving it for a while works, but it is taking longer and longer to turn on again. Any suggestions appreciated.

Sound but no picture


Most likely - the CCFL backlight is not getting the power it needs to come on. You can verify by shining a light on the front surface of the set - if you can just make out a dim image, then that is it. On some sets, the CCFL can be seen through the vents on the rear.
