Unplug the TV from the wall outlet. Press and hold the power button for about 10 seconds. Wait five minutes and then re-apply power.

Power supply module will be the first thing to check, look for bad caps, find out if it has standby 5vdc and other voltages.

I have the same thing can you turn it on using the remote.? Eventually it comes on but I have to keep pressing the power button or keep pressing power from the remote.

Check to see if the 24vdc disappear when the screen black out, it is always there then you have problem in the backlight inverter board. Did you replace the caps in the 24vdc supply also? I replace the whole set.

FAULTY POWER SUPPLY CAPACITORS

You may ahve either the main logic board problem or the power supply module problem, look at the power supply first since it is easy to do without much tools needed, look at the DC filter caps fopr leaking/bulging tops (notes: cap can look OK but may have high ESR whcih you will need caps meter taht can measure ESR).

This could be a problem with the tv's memory. Try resetting the TV. Unplug the unit for a few seconds (10-60). Then restore the TV to the factory default settings. Viewsonic has changed it's menus at intervals so you may have to check your manual. It may be Menu > Setup > Memory Recall or Menu > Options > Restore Default (or something slightly different). From there, click enter, use the right or left arrow to select YES, hit enter. Leave the menu system (Menu twice). Then hit Menu > Channels and rescan all channels.

An alternative cause of the problem may be a weak signal - check that your antenna is pointing right at the station and is the correct type to get the signal at the distance you are from the station. (Usually a weak signal would also have the audio breaking up but weird things can happen.)

I hope this helps.

(who recently had a channel pair that started out with flickering signal issues and then had one channel lose video and the other audio. The memory reset and rescan resolved the problem.)

you may have a bad inverter board. check for 24volts to the board.

Look at the power supply first; look for burnt parts, bad capacitors, etc.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.

check out this website, it's got everything you need. I have to give all the credit to Alain, a brilliant guy in France who dug in and solved the problems. he gives instructions for the professional to fix the problem, but he also gives the sources for the power supply board to be purchased and for the little chip that causes most of the problems. I decided to take a risk and save some money and bought just the chip for $20 and very carefully soldered it in after removing the old one. The tv is fine a month later. The board comes out with no soldering, just some quick connectors and the back of the tv will come apart after you remove all the screws and the base by gently prying the back case from the front bezel along the sides of the tv. if you look closely, you will see the small cavities to pry from.
