Smart tv's have their own built in computer and as with any computer they can get confused and don't know what to do.a simple thing to try is unplug your tv completely from power source including a power strip. hold the power button down for at least 60 seconds plug it back in see what happens. don't cost anything to try this.

SOURCE: red blinking light three times pause then three

Make sure that lamp door is fixed securely and pressing lamp door switch as 3 times blinks shows lamp door switch is not On.

SOURCE: red light blinking 7 times on Sony Triniton Wega TV

This means one of three things, either the lamp is bad on your tv, the ballast that powers the lamp is bad or the safety switch for the lamp door is not depressed or it has come un-plugged. It could also mean the power supply or fuse on the power board is blown. I am assuming this is a DLP tv, and if so, it is fairly easy to fix it or find parts for it online. If you are slightly mechanically inclined, want to save money and dont mind paying attention to detail then you can fix it yourself. If you need help dont hesitate to ask.

Have LG 42LD450-UA lcd tv that has no picture or sound. When plugged in the red power light comes on but when it's turned on the red light flashes very slowly continuously. Thanks in advance


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. http://electronicshelponline.blogspot.com/
Blinking codes details of many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

Hi,
Try to change the capacitors first. Normally lost of lcd tv have problems with the capacitors and which lead to powers problems. May you will not find visually that the capacitor is fault. So go for changing the capacitor also check the following video. Which will help you understand how to check the power supply broad. Also take care while working with the power board there is a risk or electric shock Also one of the capacitor in the power supply holds charge even when you have remove the power supply.

Picture went out and red light on the front by power button is blinking. When I turn TV on I can hear sound but no picture,, then TV turns off automatically after a few seconds.


Hi,
It seems problem with low screen voltage to three picture tubes in this rear projection tv.
If standby light blinks 5 times after three seconds long pause then adjust screen volts of each picture tube to solve this issue.
Screen volt adjustment requires expertise and job of professional so please call local tv repairman to help you.
Thanks.

LG 42 LCD no sound or picture


Did anyone find out the solution for this??????? I have the exact same problem with my LG 32 LCD. I only had it for a year and a half, and the green light blinks a few times and it shows no picture. Not even a red light when the tv is off. The same thing happened a couple weeks ago and by some miracle it started working again.
