Question about LG 52SX4D 52" HDTV

1 Answer

Bulb looks fine

I pulled the bulb out of my TV and I did not notice anything visually wrong with it, could it still be bad? And if its not the bulb could it be something else around it causing the red flashing light?

Good day!!!!

That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Green light just blinks with and no picture?

Is the lamp new. A lamp can look ok but still be bad. This is first thing to change. You'll have a spare if not bad. next likely the ballast.
