Question about Televison & Video
Please help with my LG 29FX5BLE-TG 74cm. It switches on and plays for some time, thereafter goes on standby. I have checked for dry joints and tested transistors and diodes, yet still stuck with the same problem
Hi and welcome to FixYa,
Appreciate the direct "Ask Me".
The LG 29FX5BLE appears to be a Korean domestic model. There are a number of possible causes for the auto shutdown as you have described. Assuming that this is a conventional single CRT TV, lets start with the vertical amplifier IC. This would be very near the 4 wires the goes to the yoke. This IC would have an aluminum heatsink and could be anywhere from 7 to 15 pins single inline package. The have been known to develop cold solder especially the Vcc pin. It may also be worth your while to trace the Vert B+ line to the resistor diode from the secondary of the FBT.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
