| If you have no picture but sound, 24 volts going to the panel and the 5 volt inverter on, bad panel not cost effective. I do show inverters are available google the full product CODE like LG 37LF65-ZC.AECYLJG then "inverter."

|
| Hello!
I have a problem with LG37LF65 first the picture has been deemed and after a while gone. I have realised that the C203 on the power board has been boiled. I have changed it and all the capacitors on the secondary power suply. I have tested the 24 V and 12V with a dummy load and everything is stable. But I still do not have a picture anly the voice. The inverter has 24V and on the inverter on pin is 4.5V so the bulb should glow but it doesn't. While making a discovery I found out that the 19V when the load is connected falls on 18.1V. If this is ok then the only thing that has left is the inverter board. Am I right ? I'd appreciate it if you could assist me with any ideas or send me a complete schematic diagram. Thank you in advance! |
