Question about LG 47LC7DF 47 in. LCD HDTV

1 Answer

When I turn the tv on, it first flashes green 19 times, then on the 20th it stays on and the screen seems faintly backlit but no indication of a signal, i.e., on-screen HDMI input selection. It's just a blank screen. I was told it was the main board but after reading this site I have my doubts and I do not want to waste time and money replacing working parts. Make: LG; Mod. No.: 47LC7DF-UB

I have a Sony Wega LCD Projection 60wf655. When I turn it on, the red light turned green and blinks green 6 or 8 or 10 times or indefinitely. No picture but after a minute of being on the screen glows...


This could be the "thermal fuse" which usualy is next to the light bulb. Part cost around $5.00. Please check your manual for directions depending on light and times blinking.

If the power light is faint it indicates a high voltage problem in the set. The only course of action is take to a tv technician to have it assessed.

The tv wont turn on the lights in the front of the tv all stay on the red and two greens and when you try to turn on the power the lights just flash and the screen stays black


That is indicating a internal defect. It's likely you will require a shop repair. Contact the manufacturer with the model number and ask for a referral. The flashing lights indicate that the television is telling you there is a failure someplace in the internal circuitry.

Stuck in standby.


Mainboard damaged and need to be replaced, try EBAY for a general picture of prices but you will need your product code wich is located in the back of the TV next to serial number.

Power indicator is flashing


Possible error on JB board - diodes D5701, D5703, D9616. Replacing them should be sufficient. Anyway, you should contact the nearest Sony Service. Regards, Arpi
