SOURCE: MY FUNAI TV WHICH IS

Hi.

If the TV is completely off, then usually it is either the power cord or the PSU. First test the TV using a different wall socket, eventually use an extension.

If that does not work, then power cord and PSU must be tested and eventually replaced.

Here parts for most Funai models.

In some unfrequent occasion a faulty main controller can cause no power. This is rather uncommon.

If the TV is in standby, then there are more parts that must be tested.

If TV is CRT, then the problem must be fixed working at component level.

If TV is less then one year old, then it is under warranty, in that case contact Funai using the form below. You can also use the contact form to locate the nearest authorized service.

SOURCE: TV goes onto sleep mode while watching and cannot

Hi well whenever this happens it is always the micro controlling the unit, that or some fault that affects the main controller and "Glitches" it, sometimes it can be caused by a damaged power supply, and the "Spikes" get through to the processor and cause it to do what you describe.
Please find below a link so you can download a copy of the service manual, should you wish to DIY?
However should you not wish to DIY, and I do NOT recommend it, my advise is to contact a local or head office from Panasonic, and ask them for a referral to an authorised service center, now ,make contact here and ask for a service call, or better yet, take the unit to the repair place, in any event when in face to face contact ONLY ask for a "Quote" this way you can be appraised of what's wrong and prospective costings, and you can than at the least make up your mind as to repair or replace? I say this as more and more in my shop i find customers are these days preferring to replace rather than repair, and put any monies that would have been spent on repairs be put towards a new unit, with a full warranty.

Techwood 32832 TV went black and now won't turn back on


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. http://electronicshelponline.blogspot.com/ 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.

I plugged in a computer and changed the input to VGA and the TV went blank


It sounds like your tv is in sleep mode.

What are the settings for the computer? Make sure it is set for the vga output. If it is a laptop, this is usually done with a function (FN) key. On your settings screen you can set the resolution and which monitor you are using.

I have a mitsubishi ws-65313 projection tv i was waching it and went black now its not working the green light is on but tv isnt working and i try to turn it off and the ligth still on i push the botton...


Hi. i believe this to be either of these three problems.
1. Power: it could be that there is a problem with the power electronic element(s). the solution is to go see an engineer.
2. Screen: if the television uses LCD display, it could be a problem with the liquid in it. Solution is to see an engineer.
3. Sleep mode: the TV could be in sleep mode which makes the screen go blank until removed from sleep mode. Solution is to read the TV's users manual to see how to wake a sleeping TV. Get back.

I pressed the sleep button by accident and the pic and sound went off and the stand by/timer red light started blinking. what does it mean?


Depends on how many times it blinks,just count the blinks Example: if it blink 2 times then pauses and blink 5 times then the code would be 25 and so on

Once you have this code,please post it.

TV will not come on with remote or power button


The following instructions are for the Emerson EWC1303/1903 tv/vcr. That's the closest match I could find to the Spongebob Squarepants 13' TV
If it's actually in Sleep mode, do the following:

TO CANCEL THE SLEEP TIMER
Press the WAKE UP/SLEEP button on the remote
control until “SLEEP TIMER” appears.
To view the time left for sleep timer press the WAKE
UP/SLEEP button twice, then press the MENU button
on the remote control to exit the sleep timer setting


If unsuccessful, try unplugging the TV for 1/2 hour, then plug it in and try turning it back on either manually or with the remote. Either of these should solve your problem. Best of luck to you!

Sleep


If you unplug the unit for an hour or overnight, it should go out of sleep mode. If this dosent work then its not in sleep mode and the set has a problem in the power supply or the sweep circuit. Sorry you should seek a pro to assist you in this repair. Good Luck
