For people who have experienced this issue in the past there are five capacitors which dry out after a number of 4 years. they are 4700uF 6.3V x 2, 2200uF 6.3V and 1000uf 16v x 3. on the power supply board of the TV. They are obvious to spot as there is a defined bulge on the top where electrolyte gasses have expanded the lids. This is normally due to low cost crappy capacitors. Capacitor life in general is about 8000 Hrs continually used, so if its running for 5 hrs per day, you can expect a minimum of 4 to 5 year out of the televisions before experiencing power supply issues. Additionally there are two diodes in the power supply with small heat-sinks attached. These devices get somewhat warm and the joints around their legs if no soldered correctly at the time of manufacture become weak and crack.
Sorry cant solve your problem but i have exact and i mean exact same problem including argos and receipt problem maybe a bad batch where are you my e mail is [email protected] maybe we could approach argos together ?
