Philips TV sticks on standby and wont turn on. Help please?

I think your TV is broken. A TV will lock itself in standby mode if there is a fault on the HT circuit. Common cause is the LOPT driver being short circuit.

Needs professional attention.

Or, if you are brave, the DIY method:
Look for a large rectangular transistor some where near the transformer with the HT lead coming out the top. If you are lucky, no other damage will have been done.

I must point out that there could also be a lot of other faults aswell. ( Line Output Transformer, Capacitors etc...)
PS: If trying to buy a replacement transistor, it might have a number like D2039 on it - you may need to put 2S in front of this number ( ie: 2SD2039 ) for buying one.
