When i switch my tv on it turn's itself to standby, i can switch it back on again but it just keep's switching itself to stanby after a couple of minutes.

Hello Mike, seems you have a problem with your power-supply board....*or check if the tv switched back into standby mode..if tv switched back to stanby mode .....please check your A/V <Main proccessing Board...
Hoping to inform you correctly I remain,
Yours friendly.

Blessings.

Unplug,replug the tv an hour later,let the tv reset itself,might work again.

Hello Charliebigwh, hi technically your monitor's power supply has a problem, this is either your switching regulator does not work or there is a short in that section, If you want to do it your self, need to replace all large value, and or high voltage capacitors(especially the capacitors with its top is bubbly), need also to replace the switching IC, and power transistor.

Have it checked by a technician if you cannot do the work.

your h.o.t. horiz. output transistor is more than likely shorted and this is how a switching power supply protects itself it does a self test and if parameters and current/voltage aren't correct this is what happens

Sorry to here about your TV problems but it is almost imposable to help someone with technical problems if they don't list a product, model or P/N number.
Either-way, I would try moving the unit in an area where it has more breathing space if poss-able.
Also, is the unit in a air conditioned area or in a Damp basement or Florida room ?
I would also, go on line and see if Panasonic has any call backs on this unit.
This may be a feature which can be reset without to much trouble.
Next time please list the size & model #.

I managed to find a local repair man who fixed the problem. He put in a new transformer.

get a new TV :)

According to Sharp it is a software problem. Engineer came, installed software update ,10 minute job.....TV worked fine for 1/2 day unfortunately: Then images turned black and white in all channels TV turned itself off, and stanby and OPC buttons started flashing. When TV came back on its own 10 mins later , screen had 2 large square staines superimposed in image (as if it was a burnt screen)...Engineer will be back next week...all quite sad really for a new TV.....will keep u posted

Could abe your Regulator IC, or cold solder joints.

Right i had this same problem for ages! i cannot explain why but when i uplugged my DVD player (which was flashing its light at the same time as the tv for some reason) the TV has worked fine.
