This TV set showed up to my shop with the dead signs. No stand by light, nothing. Just a dead set.
For me I do not like the Philips TV sets for they are very complicated to work on and sometimes, they give me a hard time repairing them. I just do not like them. This TV problem is very easy to fix because I found out later that only one item was blown in this set and it cost the whole TV to shut down.
Once opened the back cover of the set. I headed directly to the power supply and looked for a capacitor with the mark (222K 2KV). In this model only you can find this blown capacitor. Once you replace that, it will work right away without any complications.
The main problem is getting to this capacitor. If you are not familiar with this set, it is going to take you a while to find it because it is hidden under a metal box. Under that metal box, you will find it among other capacitors. It is usually blue and it is a resin disc ceramic capacitor. In order for you to get it out, you have to take the metal box out and then take out some capacitors from the PC board to get to this capacitor. Make sure you mark all the capacitors so you will be able to put them back on board. Once you get to it, just replace it with the same exact specification, otherwise, it will not work.
It is a very easy fix. Enjoy the repair.
