Sagem 45 inch rear projection tv keeps switching off

My tv is 3 yr old and has started switching to standby everytime its switched on, gets picture, sound etc fine for about 40 seconds then switches off to standby, you can do this all day and everytime its switched on it works for up to a minute and shuts down again.. read somewhere it may be dust build up affecting the fan and its closing down due to safety mode, does this sound right to anyone as i dont want to open it up unless im sure cleanin it out will help.

It is most likely some bad capacitors on the power supply board that are causing it to go into "safety mode" and shuts it down.

SOURCE: Panasonic VieraWidescreen Plasma TV Model No TH42PA50A - Power standby mode and tripping off automatically, Please help

Hi, you did not say how many times the red led flashes. This is an important clue as to where the problem might be. On some 6th generation plasmas, a regulator in the power supply could cause that problem and had to be replaced with an improved version.

SOURCE: tv keeps switching itself off

When that happens - try unplugging the tv for a few minuets & plug it back in.. Sometimes it will reset its self.. Or it could be a bad sercut or maybe a falty power suply.. Electronics is usually process of illimination - unfortunately..

Please also disconnect everything from the TV apart from thee power cable as it may an external device that is causing the problem.

If there are touch buttons on your TV, make sure they are not touching anything and they are clean.

Remove the batteries from your remote control as this could also be turning the TV off.

SOURCE: problem with panasonic tv

It is usually caused by problems from lead solder that sometimes does not connect, so there are some points of the components that are not connected with lead solder to the circuit. if it appears vertical line means from the IC (integrated circuit ) Vertical, you can solder all the points in the IC ( Integrated circuit ).

My 10 yr old Sony KP-51WS520 rear projection tv come on for about 10 seconds and then shuts off.


Sadly yes. that is repairable but a 55" flatscreen TV is pretty reasonably priced these days. It will use a lot less electricity as well.

This is bad. You need to either be under warranty on these big screen TVs or get the service manual. Especially since this is an off brand.
