there is only a loosed part at the printed circuit board. try to open the back cover of your tv but be sure to unplug it before doing this, then try to unplug then plug the connectors in the power supply part but be sure to remember each location of the connector.

Hi, i have a Thomson Intuiva TV. Its been working fine untill recently when it started turning itself off! I only use the tv to play my Xbox 360 Slim. I left it over night and tried again today but the...


This is a common fault in many electronic systems . when the set ages it deteriorates in the connections. There is a high possibility that the components over a period of heating and cooling, tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs or poor performance.

The best way to check for loose connections is to tap lightly when the set is powered on , If there is change while tapping then it seems that there are DRY solder joints. Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points.

Sometimes the fault occurs when the set warms up, if so you can simulate the heat using a hair dryer on the suspected areas, try with the power supply, distribution, Processor controller, driver controllers on the A/V related sections. Also the use a FREEZE-IT spray can simulate the components to cool and show up the fault.

Based on the above method you must be able to locate the area of fault and solder the sections. Sometimes large IC's- ones with more pins- tend to have drying in some pins and so cause faults related to the IC's protocol. Have a rough idea of looking into the areas to reduce the time of probing.

When i switch my tv on it has a habit of switching itself off. The red light will still be on and a little green light below it flashes. some days it does it somedays it doesnt. Some times it does it once...


The television is switching itself off to protect itself because there is a problem with it. It may be a bad capacitor, which is usually the case but you have to catch it before it gets any worse. Because then the television will switch itself off and not come back on. The light will just continue to blink and on top of replacing the bad capacitor the entire board the capacitors are attached to might need to be replaced as well as the power supply and main board. Please do not keep turning your television on while it needs repair because it will put itself into a coma and contact a service provider asap.

if you bought it under one year ago then the retailer should be obliged to either replace it or repair it. I would look into this further, ask to speak to the manager or something casue when a tv switches itself off it indicates an error inside and turns itself off to prevent further damage.
