The problem is that the TV shuts down after about 10 to 15 Min. It just goes black and you can not turn it on again. For all I know, it is still on but the screen is black and the sound is gone. It does seem to make some noice out of the switching power supply but I'm not sure. Any clues? Thanks TK

Re: Shut down problem
Are the lights in the front flashing? How long have you had the tv. The lamp is probably the issue....they forget to tell you that they have to be replaced every so often and they are expensive. You will need to take the lamp out and make sure you get the correct replacement. I found one reasonable priced on the internet by searching for the model number shown on the old one. You can change it yourself if you are handy at all and have the manual. My friend did not have her manual of course so I had to find that on the internet as well.....Good Luck

Hi Bob, The link below is a YouTube video showing how to fix a RCA television(DIFFERENT MODEL) NO picture GOOD sound, Also there's videos down the right side of the link that may help as well........CHEERS..
Start simple by using different cables, whether they be HDMI, VGA or standard COAX cables. They could be losing the connection. Also, it's possible the power supply is wearing out and it gets too hot. You might want to simply try some spray air duster type thing to clear out any dust that can make it hot.
Yes, cooling fan could be a problem. Just see whether it goes off during before shut off. If yes, the TV might need service. To know whether the fan goes off first or the TV, stick one side of any thin vibrating membrane such as a silver paper (like the one you see in cigarette packets) on the fan outlet, without blocking it, so that you can see whether it stops before the TV shuts down. Alternatively you can hand an inflated balloon which keeps flying off from the area of the fan and shall stop when the fan stops. I suggest this, in order to save your time looking at the rear all the time until the TV stops. Even then, one is likely to overlook whether the fan stops or TV stops first.
There is circuit problem inside. For safety reasons power might get shut down! Unless the fault is rectified, this problem will continue. Do not attempt switching ON again & again. Get authorised service center assistance.
there is something overheating in your tv... the causes of this might be the vents are being blocked, maybe they have too much dust or there is a tshirt or a towel on your TV.
there could be some resistance, fuse, or transistor overheating making it to shut down to prevent a massive burn out briking your TV
if its a PC.. in wich im not sure if its a tv or a PC.. but if its a PC, its that the CPU isnt getting enough vent.. so replacing the thermal past from the CPU and heatsink will make the temperature go down, also, try checking if the small ventilators are working correctly.. if the dont, change them all.
to make cheap fast repair.. get an air conditioner or a huge ventilator and make the thing get some air
