Display powers of with power up of AVC

Unit is five years old and until now no problems. Following suggested power up process (1) dispplay Main Power on yields red to blinking red expected. (2) AVC Main Power on and Display red goes off. Attempts to immediately repeat sequence yields no red light on Display when pressing Main Power button. Can only repeat process after diconnecting power cord for Display and AVC unit for an hour or more. Was able to gain normal expected Display functionality once, over two day period in the course of following these steps, maintained normal TV operation. Following normal shut off, back with same problem.

How many blinks does the red light give in a row? This would be an error code?

The problem for 7 blinks would be an Interface board. Apparently there is a glitch in the interface board that sends signals to the television. Basically the glitch shorts out the board and the t.v wont turn on and you will see the power light blink 7 times pause then 7 more. You can replace the board with a new one and update the software on the new interface board.


If is isn't 7, let me know and I will help you out with this

thanks

Sharp Aquos LC45GX6U & TU-GD10U. The unit doesn't power up, and has a red blinking light from the moment you plug it in. The unit works fine in service mode.


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 to many popular brand TVs are given. Surf the site with patience. If blinks continue without any pause, the main board is faulty.

No picture, green flashing power light. How bad is this?


The flashing indicates something is wrong (missing or bad) the fact you get the display means panel (main screen unit) is good.

This suggests to be (instinct) the main board that processes all signal from all inputs is bad; it could be a missing voltage in the power supply but a check with a voltmeter would answer that.

The problem here is you can check a few things and then you are in a position where you have to gamble and buy and try a board.

It can get expensive to fix it this way---gone are the days of looking for one bad part (they only sell boards) and with that the lifespan of these (all brands Plasma and LCD etc) are 3 to 5 years.

Red light on display not green as usual no power


Hold down the "input" button and "volume -" button while the MAIN POWER BUTTON IS OFF. Then turn on the main power button while those are held down, the light on the tv & avc box will turn green. When it turns green, immediately let off the 2 buttons and press "volume +" button, then press the "Main Power" button. Next step is to repeat the process about 20-40 times & the TV WILL WORK!. I have read that this may have something to do with the energy star compliant commands that can changed through the serial port.
The above is from psxpirate25. Thanks!
I had to repeat the whole process a couple of times to get rid of the factory setup firmware mode. Do it 40 times, I would mess up the sequence a couple of times. Keep trying, it does work.

Sylvania 6842-PEM Flickering Problem


Something is breaking down. Possibly a specific ceramic capacitor on the main power pcb that has been troublesome. Usually there is just a loud pop and the screen goes dead. If the set is less than a year old it is still on parts warranty and the technician could just change circuit boards until the problem is gone.

Display powers of with power up of AVC


This is the problem with my LC-37HV4U. I plug in the AVC and the tv/monitor and I get both red power lights (not blinking) but no green lights, sound, or picture. I mean the tv screen stays black! It seems like their is no communication between the AVC and the monitor. I thought at least the screen would light up when the power light came on and being it has it's own power source. This tv is driving me nuts!! Can anyone please help?? Thank you.

Sylvania 6842PEM


Have fixed a bunch of those as a Sylvania ASC. There is a small ceramic capacitor on the main power PCB that has ruptured. It must be replaced with a different part, a special type of capacitor, or it will just fail again. Sylvania had recommended replacing the main power PCB rather than repair because sometimes there was additional damage on the board, however replacing the capacitor fixed every one that came to us. I preferred that because some electrical voltages have to be adjusted if the circuit board is replaced with a different one.
