    When switched on my 8 years old Philips Model 21FT240B / 94 R from cold, it works for about 10 minutes and then the screen shuts off from the left side and then switches off. Red stand-by light flashes continuously. I have to go and switch off the TV Power Switch / Electic Plug switch, to turn the TV Off completely.Then after, say 1 or 2 minutes, if switched on, for about 3 to 4 minutes, it will work, and then again it switches off as mentioned above. Any solution ? Or do I have to change the TV and buy a new one?

Good day.
This is a common problem for all television however, for us to isolate the concern better, we will need to have the model and brand of your unit.
Ussually, this problem is associated with the vertical circuitry. It can also be traced on the low power supply section such as the system or chroma ICs'.
Response is higly appreciated.

Hi,do you hear any strange noises? If you hear clicking or like wanting to turn on it could be the board that powers the lamp it's called the ballast.Here's the instructions to replace it :http://www.fixyourdlp.com/guides/samsung/bp47-00033a.php But if you don't hear any strange noises,tv is around 4000 hrs,1-3 yrs it could be time to replace the lamp.The lamp you need is 915b403001 .Have a blessed one!

I own a Sony T.V. model #KV36HS510, Serial # 9024184,Event# E36002407 and it"s aTrinitron brand name. Like the problems before no picture or sound, stand by light on front of unit flashes. When trying to turn it back on you can hear the power click, like it wants to turn on, but does not.
