SOURCE: why is my seiki 32 tv picture blinking off and on

Fault to the main power supply regulator section. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

SOURCE: My Seiki TV lost sound. Turned it off a few hours earlier. When I turned it back on Tv had no sound. Picture was perfect. Never had any problems with it and Tv never abused. . Use cable remote

Check whether the audio is muted by accidental press at remote control button. Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, Check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis. If you wish to get some details; check the site linked here. Pull up older posts.

Volume don't work to tv


In the menu for audio, there will be a selection for TV speakers on or off. They are probably switched off.

Audio is not working


Is audio out on all sources? Check mute button on remote. Check audio in tv menu. connect audio out of tv to external amp. Like the aux in of your stereo receiver. If you have sound there then next remove and test speakers. touch wires of speaker to a aa battery.Be sure wies are disconnected from main board. Speaker make no sound then replace them . If speakers pop then replace main board. or board that has audio amp ic on it.

if its the button the front keyboard will need replacement. You can check the tact switch on that board. If the switch is working then the main board would be suspect.

Shut tv off at night . went to turn on in the a.m. and would not turn on !!!T


There are a couple of capacitors on the board that will go bad 10 uF 450 volt electrolytic capacitors
they will be raised on the top of the capacitor or maybe discolored.
I have had another brand of tv that did this but just had the red power light flashing and I held down the power button with each other button for a few seconds. example hold power and volume down then go to power and volume up ect. even try menu and the other buttons. then unplug tv for a few seconds and plug back in and power up. it might be worth a try.

Turns itself on and off every few seconds. The blue light at the front of the TV stays on steadily during this process. Tried unplugging it but made no difference.


When you unplugged it, did you leave unplugged for quite a few hours? And in the meantime of being unplugged, did you press and hold the power button for 5 full seconds, and then wait half hour more to plug back in? If you did this and it still is the same, then you likely have either a loose wire or solder joint or your high-voltage transformer is likely bad.
