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.

Red flashing light


  1. Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. Check video out, Q705, 732, 761 and other components on the C board, also check Q218, 219, 220 on the A board. In addition, unit could be in IK blanking, try turning up screen slightly.

Digital tv -analogue vcr records and time records and plays back only with the picture on. It will not record with picture on standby


Of course it won't record if the TV is in standby as there is no signal. If you wish to record TV programmes without having the TV switched on, you need a freeview or freesat box for your Video Recorder.
Hope this helps.

I pressed the sleep button by accident and the pic and sound went off and the stand by/timer red light started blinking. what does it mean?


Depends on how many times it blinks,just count the blinks Example: if it blink 2 times then pauses and blink 5 times then the code would be 25 and so on

Once you have this code,please post it.

'standby' mode and akb error number


AKB 66 in self diagnostic test means...TV goes to standby (shut-off) for AKB problem 66 times. AKB is White-Balance signal and it is not proper or maintained in your TV. So error signal produced and TV goes to shut-down state.
Regardnig Standby button, its available on remote only. If you push TV Power switch, TV will switch ON, push it again to OFF TV. Power Button on remote set TV in standby status and you dont need to push power button of TV itself.
