Help I have no picture, no sound. red light on front, 3 out of 4 green leds inside.

It sounds like the tv is powering up correctly, but it does not display anything, and the sound does not come on either. remote won't power up the unit or shut it down. the button on the front is red, and 3 of 4 LED's on the inside are green. fuses are ok. Thanks!

Panasonic plasma tv turns on but no picture or sound

Same issue with - Panasonic TH-50PX70A , power UP with red standby, then power ON by remote - only Gives GREEN led blinking 35-40 times, followed by solid green led with no no picture no sound.
>> Solution; unplug Plasma from AC 10-15min, then plug in & power on to Red standby led,, At this point - Power ON tv while holding down both -Volume Down and F (function Select) buttons (front panel door) at the same time turns picture ON,all ok.

No Picture & No sound. Red LED, Green LED, Red LED.

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

AKAI LCT26Z4AD wont power up.

Those 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.

No picture or sound

Remove the rear panel. With the TV on you should see a red LED near the center of the PCB. There should also be 5 green leds, 3 to the left a 2 behind. If there is no red leds, check the fuses. If there are no green leds or maybe 1 or 2, disconect PSD5. It's a connector on the left side of the power board that connects to the audio board. It's the 3rd on fro the back. It's labled. With that disconected, turn on the set and look for the green leds. If all 5 light, the power supply is OK and you have a problem beyond that. If they don't all light you have a bad power supply.
