This would be a shop repair in most cases----yes, some people (my self included) have resorted to a small high speed fan to locate the area that is getting too hot etc---if you find it the fan will prolong the operational time--the real reason is to find which board is bad which is how these sets get fixed---replace a board-----keep in mind that it is possible to change each and every board and to still have the problem------screen unit can be bad and that is fatal.

Older-model Toshiba TV shuts off by itself


There is a large sand filled resistor on the main board close to where the power cord attaches that cracks. This will stop power until it cools enough to make the connection then heats up rapidly to open it again. It may be worth the trouble if you're handy with a soldering gun and can get the back off the TV. If not then I'd consider getting a flat screen.

My Sharp LC-42SB45U takes 15 min to an hour to turn on. Also, sometimes picture blacks out for 10-15 seconds. Any suggestions? Pat Courson


Have same problem. Not the proper fix though I found that taking the back off and heating it up with a heat gun for 30 seconds to 1 minute and tv works fine till you shut it off over night.Maybe someone can offer a solution with that in mind. Pretty strange

Who do I determine what causes my tv picture to turn off


if your tv is one of the latest 2006-2012 it should have a prosesor and a heat sink on top of the prosesor, if the heat sink is not proparly positioned or has moved out of position due to unknown circumstances then all you need to do is reposition the heat sink you tv should work just fine.

I have a HP PL4245N plasma HD TV. sometimes while watching it just shuts itself off screen goes black and will not turn back on unless I unplug it wait 20 seconds and plug back. Then it works fine. it...


Hello
I thinks you may be right. All plasma and LCD panel tVs will have cooling fans at the top side. Plasma screens will heat up much more, and if cooling fans stops work, of has damaged, the set will overheat, and awill automatically shut down; because there is a overheat sensor fitted inside it, will sense the heat, and if the set overheats, it will send a signal to the main system control fo the TV; which in turn shut down the whole system. look fans for proper working. If not replace them. OK.

I have a sony KP-51HW40 and when i turn it on about 5 minutes later it shuts it off.


If the TV works fine during the 5 minutes its on then your power supply in the tv is heating up and shutting off. If you have some mechanical knowledge you can buy another power supply from Ebay for around 35.00 and replace it. will require some soldering

Sony Dlp, 46" shuts off, cools off, then turns


This is probably a heat issue (assuming you aren't the one turning off the TV and aren't having regular power failures). This TV has two fans to help keep the components cool; if the temperature increases, the TV will shut down to protect those components. Also check if the ventilation slots are blocked and clean the dust off them. (When you have the TV open, you can blow out dust as well - much like dust removal for a desktop CPU.)

For replacement fans, you can go here: http://www.partstore.com/Model/Sony/Sony/KDF46E2000.aspx .

I hope this helps.

Tv keeps turning off


If it's staying on for just a short period of time it sounds like there is a sensor that is giving the unit a faulty condition (Perhaps for reason or due to a fault in the sensor). There are normally a few temp sensors in the TV around the Lamp and Ballast. They may be bad, or the lamp or ballast is just generating too much heat.
