SOURCE: LG LCD TV Standby Light Flashing Red Continuously

I have had this same problem twice in the past 3 months. So far both times I've been able to get it back after a week or two. I'm not sure what works, but unplugging and detaching the antenna and cable and waiting a few days seems to be the key. In both instances, I unplugged it for a few days then plugged it in for a few days and repeated the processes until I eventually got the steady red led. Both times prior to the red led the led would flash red then green and make a clickiing noise for several hours before I was able to get it working again.

SOURCE: no pic but sound

My experience is that the Z-sus board has blown! . this because a little power supply on the Y-sus board is defective. This power supply feeds the drivers for the Z-susboard. replacing the Z-susboard will result in a working tv but it will allso blow sooner or later if the little powersupply on ths Y-sus board isn't repaired first! this little pwer supply, supplies the +15 volts for the gate drivers of the Z-susboard and if you measure on those gate-drivers you'll see that the supply voltage has dropped considerably due to bad elco's on the little power supply on the Y-sus board.

Replace those bad elco's first before installing a new z-susboard!

I have lg 47 tv that sud pic stop has sound when you turn on you see a light for sec


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.
http://electronicshelponline.blogspot.com/
To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

Lg 37lc55-za power problem


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.

Stand by light on sony mod#kv36fs120 blinks 4 times then stops then 4 and so on no pic or sound


A 4 flash shutdown indicates some type of power supply problem. It will be necessary for a tech to take a look at the TV to determine where the fault in the power supply lies.
