Question about Philips TS2546C 25" TV
If the set works fine intermittently it may be a loose connection or a bad solder joint. More likely the later. Heat will sometimes make a cold or broken solder joint work. If this changes when you lightly tap on the side of the TV you have a bad connection of sorts inside. These repairs can be expensive unless you find a good repair person.
The syncronizing signals in TV's (keeping the picture locked in) are around the high voltage transformer which is usually the heaviest component attached to the circuit boards. It's stressful over time and I've seen the solder connections crack and become intermittent.

I have seen this on mine. Check the cable going into your TV and make sure it is good. The ground portion of the cable could not be making a good connection.

You most likely have a bad picture tube. Green gun is shorted. Usually a set this size is not economically feasible to put a new tube in. You may also have a green drive problem on the CRT board. Have a shop check it out for you before junking it. Thanks for using fixya.

if you have back ground of tv repair, remove back cover but you need tools and tester, check heater line from crt ckt board going to horizontal section.

It requires a professional repair, the problem lies either in the power supply section or the line output stage. There are high voltages present so unless you are qualified I would not open it. I would say that it is unlikely to be economical to repair , you might want to think about buying a flat screen led backlit model, and as a bonus you will save electricity too.
I hope I have been of help but please do not hesitate to ask if you have any further questions.
I appreciate your vote if you appreciate my reply and remember, even if you don't vote for me a please and thank you goes a long way.
