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.

How to fix my flat screen t.v.?


Check all the AC input connections. As the power board is new, the TV should show standby light at least, when you switch it ON.

Check whether there is a line fuse inserted at AC path. Check whether there is a plug-fuse included inside the power plug.

Toshiba Satellite won't start up when AC plugged in


Try another Cord/Charger to verify the Cord, AC jack. If you plug in the AC cord after starting on battery, does the battery charge? Open Control Panel, Power Options, set to High Performance, Advanced power settings, set Sleep and Hibernate to Never, Adjust Advanced power setting to your preference.

Red light is on in the back of my t300 tower speakers


That is the standby mode but if its not kicking out of standby mode it could be a fuse issue

The T300 uses a 2.5A fuse.

To replace the fuse:

1. Unplug the AC cord from the AC power source,

then remove the AC power cord from the speaker's

power connector.

2. Remove the fuse cap with a small, flat blade screwdriver

(see diagram 2).

3. Remove the fuse from the fuse cap

(see diagram 3).

4. Replace the fuse inside fuse cap with another metric

5X20mm size fuse

5. Replace the fuse inside the cap, replace the fuse

and cap in the power connector (see diagram 5).

6. Connect the AC power cord to the speaker and

raise it upright.
7. Connect the power cord to an AC power outlet

The power will not come on


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 the power cord is fused, then replace the fuse in the AC power plug.
If that does not work, then power cord and PSU must be tested and eventually replaced.
In some unfrequent occasion a faulty main controller can cause no power. This is rather uncommon.

If the TV is instead in standby, then there are more parts that must be tested.
Forced standby is a mode that is often called protection, and that will start up when the main controller boards detects a fault or an incorrect voltage.
In this case the PSU is forced to standby (only +3.3V or +5V active). The technician must test parts individually to find out what part needs replacement.

If you want to verify your warranty status, or if you want to book a repairer you can ring the support number listed in the TV owners manual or in the TV manufacturer's website.

Regards.

Ginko.

I want to try a very simple thing, cause it happened to me, while I am working on my computer , it shut down unexpectedly... cause the processor is working with its full performance and no enough cooling around the laptop. so while I move to other place and also I raise the laptop a little bit from the back to let the fans (bottom of the laptop) works perfectly .
try to open it again and do so.... may be it is a so simple thing that was far from your mind like I was before... good luck

Connection problems


Attach the AC power cord or adjust the power saving mode so the unit does not go into "standby" mode. This is caused by the unit going into "standby" mode when data is being transferred.
