The LCD Panel failed. There is no easy fix but try to get the T-Con board to fix the issue. However, this part is usually only available with the whole LCD Panel. This is usually the most expensive part in the TV and the whole TV needs to be taken apart to replace the panel.
Might be economically viable if you can find a place that carrys the T-con but Dynex parts are usually hard to find. The LCD Panel part alone will exceed the cost of the TV.
the montor wont turn on? or the pc? the lines mean you may need to have the bulb changed. The bulb should last up to four
years but sometimes you get a dud. It also depends on whether you
bought the TV new or not. If that's the case, you don't know how long that TV
ran each day or for how many days it was on display.
The most common problem with this Model is the Caps on the Main Board, but to make sure pull the codes. Follow this procedure:
This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source) 1. MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB.
Good Luck, big IRISH.
