Re: Philips TV keeps kicking off(lose of power)
What you have there is a PTV915 chassis that has an Ssb board failing in it... To be more precise the smt (Surface Mount Technology) caps on the Ssb are failing. The board is mounted on the Lsb (Large Signal Board) vertically, just behind the tuner.
The module itself is Philips original p/n# 313912725871 and has been subbed to Philips p/n# PH3912725871 they're about $275.00 dollars.
Or you could take a risk and order one. But I'd still have the technician come out and install it for you... There are some star screws, which Philips has some infinity for, that are kinda difficult to get to and they need to be removed to access the module and extract it...
Hope this helps!

Remove all batteries from any remotes in the room. Unplug the tv. Wait several minutes and power it back up. Use the controls on the unit to turn on etc. If the unit still changes channels you probably have a tact switch on the control board which is sticking or shorted out. Unless you have dealt with this before you will need a tech to fix it but the good news is it should not cost very much. Let me know how you make out.
Your convergence board is faulty. Common problem for this model. Pull the back cover off and look to the north and look for a jumper jack [1516 i beleive] and pull this off. [TV unplugged of course] Now plug in the tv and power up...If the picture is distorted you have bad convergence ICs. If picture is good...you may a bad audio IC. You can do this, just be dang careful and good luck to you!
The TV stays in standby because protection circuit kicked in.
Protection kicks in when an internal fault had been detected.
In your case the SCART cable may have caused a short.
When on protection the TV will stay in standby, will not respond to buttons or remote, and will not start up. All higher voltages from PSU get shut down by controller board, and only the +5V remains on.
To attempt resetting the TV, disconnect all video cables, disconnect the power cord, wait about one hour and plug it back.
If TV does not restart, then there may be an internal fault.
In that case leave TV unplugged for longer, just in case.
If still no luck, then call Sony to discuss a repair. The number is listed on your owner manual.
If instead TV will restart, do not use the faulty video cable again, this can damage your TV.
I have the exact same problem! I have it hooked up to a power strip now to unplug it by flicking of the power strip and waiting for the red light to go out then I turn it back on while Channeling up 10 X's and then down and up until it comes on. I listen to the sound of the switch which it comes on. I turn it off if it is faint and then back on and channel up. Crazy process but it's been working. It takes about 10 minutes everytime to get the TV on until I get a tech to come out and look at it. The capacitor keeps a charge which is why the light is flashing with a code for 60 seconds./JJ
i unplugged the tv , turned the lamp switch to off . I left it unplugged for a few hours . I then plugged the tv back in , hit the reset button , located on the front bottom left . I waited for the timer light to stop blinking , then turned the lamp switch to the on position . I turned the power on to the tv . i heard the fan kick on , this time there was not a dragging sound . the screen lit up and i have not had a problem since yesterday . i think that the problem started because the tv had been left on for too long , I know that what i have done is only a temperary fix . but as long as I dont forget to turn the tv off , i should not have a problem
that is usually related to the LSB large signal board will eventually need replacement. Most repair shops will not troubleshoot the LSB at component level, they will opt for replacing the entire circuit board. If you need more info or help to locate a LSB board. please let me know.
