SOURCE: TV turned itself off, won't turn back on

I had the same issue with my 42HP95 after about two and a half years. Same symptom, red flashing power light, reset doesn't work and most of all, the last day of the Ryder Cup starts in 3 hours. Any other time (with exception of SuperBowl Sunday). I frantically searched the web for like symptoms and came across someone that posted the fix was to bypass the Seine Module but I had no clue what that was! So what do you do? Tear off the back of the TV and look for something that says Seine on it... Right! After that failed and 500 screws later, I decided to look for a Service Manual online. Nothing like RTFM (Google it!). I paid my $11.99 for a download Service-Manual.Net and found what appeared to be the Seine Module (SEIN). Through a little trial and error, here is what I came up with. The pic below shows the location of the said Module in the red rectangle.

78c6772.jpg I ultimately found that if I unplugged the connector from the module (in red circle) and put it in the cable management loop (other red circle), the TV would power on and has been working ever since.

According to the post I read (grains of salt) the SEINE Module is only needed if you are using coaxial type (rabbit ear) antenna. I personally don't know but it works for me. Granted, this is my experience and may not work for you but for $12, I am a happy camper. BTW, what a Ryder Cup!!! USA USA USA!!!

SOURCE: Tv cuts off and green light flashes

If your set was manufactured around July 2005, you may need a firmware upgrade to solve this issue. On the Sony website you can enter your model # and serial # to see if you TV is affected. If so, it is easy to have done and may be free from Sony. It sounds like the issue they described in the writeup on the required formware update. I had mine done within few months of when i bought it (purchased in Dec 2005) and it has been working flawlessly since.

Good luck!

When using the LCD TLP711U projector for a short time it turns itself off and will no start even after pressing the on button. After waiting a while, turning off power am able to turn it on. This keeps...

It sounds like you have an overheating issue, Look through the vent slots and see if you can see a build up of dust. If you can then you will need to open the projector to clean it properly. You could try blowing it out with a compressor but be sure to use one with a water trap to stop moisture getting into the projector. You can buy cans of compressed air from electronics stores if a compressor is not available. Some models of toshiba also have issues with the temperature sensors, They are attached to the metal heatsink and the plugs that attach them to the circuit board can loosen which makes the projector think it has overheated.
Hope this helps

Keeps turning itself off. Reckon its an overheating issue.

LCD TV turning itself off is not necessarily overheating.
Often, because of a faulty component, capacitors can accumulate electrostatic charge until an error is detected, or a fault condition can last for a while, until a problem is detected, and the protection circuit will force the TV to shutdown.
The only temp sensor that can shut down because of overheating is placed on the main board, and TV shutdown after a while is often not caused by overheating on LCDs.
Parts that often cause shutdown after a time are Power Supply Unit, Inverter, and main controller board. Parts must be tested to find the fault. The technician can follow the diagrams detailed on service manual to find the fault.

Tv switches itself off then back on again

It seems that the back light is malfunctioning or needs to be replaced the fact that it turns off after a few seconds indicates that is getting over heated. All LCDs, Plasmas and Projection TVs come with a shut off switch witch will turn of the monitor when a spike on the temperature is detected this is to protect the system from overheating. Now before you think about send it for repair; is it well ventilated? Does air circulates around it? Good luck!
