LG 17LX1R flashing red LED - TV won't power up


Try changing the input device to something you are sure, works such as a DVD player.

Switch off TV manually, switch off power, remove plug and retry after 48 hours.

If problem persists, please refer it to a qualified service technician.

Toshiba 37AV500U damaged thru HDMI input.


The lightning stroke has been effected to the main digital board to your TV. It will be best to replace the main digital board as card basis, rather than trying to repair it. Before replacing the board, a through checkup should be done. Contact any expereienced service technician for help, as this work is a very skilled one. No body can predict about the damages to a lightning stroke, as there will be trillions of voltage present for every stroke, and even a slightest voltage can damage so many components in a TV like equipment, as it is designed to work for 110 or 220VAC.

Philips 20PF4121 LCD tv no picture but flashing error codes


I had exactly the same problem When the TV was switched on all I could see was a flashing green light. After cheching the TV internals and not seeing a problem including the power supply unit which looked and checked normal. Here is what I did to get M TV working again.
Disconnect it from the power supply. Hold down all the buttons simultaneously i.e. the on/off, the volume, the programme, menu buttons, all of them simultaneously and Plug it into the power supply again.
Lo and behold My TV jumped back into life after an absence of about 4 weeks.
Try it yourself exactly as above.

Best of luck.

Samsung lcd tv ltm1755b won't turn on (power light stays red)


Problem: Samsung LTM1755B with only a blinking yellow LED when you try to turn it on.

Solution: I just had one of these come in. I opened it up, and found the U501 capacitor a little suspicious looking, in that it had a deformed top. It was a 470uF 16V electrolytic 105degC 10mm x 12mm. I replaced it with a very good quality 1000uF 16V electrolytic 105degC 10mm x 16mm Nichicon UHN1C102MPD. After that repair, when I tried to turn it on, the LED was yellow for a second, then green, then I got a picture, and it appeared to work great. I then asked the owner a week later how it was working, and they said it was working just like new!

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.
