The TV keeps going into standby mode , comes back to proper picture and with-in 15-20 seconds goes back into standby mode. It happens continueously.


Hi,

May I know if the standby led light at the front panel is blinking, if so please count how many times it will flash to determine the error code? If not follow the steps below.

In standby mode press the button of the remote control in sequence, " Display ", " Channel 5 ", " Vol (-) ", " Power ". Self diagnosis screen will displays. Le me know the result.

Projection TV Phillps 60PP9202/17F, bought 2004. Was watching and suddenly the picture went out. All connections are good and components work. Can you help?


Hi.

If there is no power at all, then it is either the power cord or power board inside the TV.

If after the fault the TV went in standby and does not wake up, then the TV is in protect mode.

In protect mode higher voltages from PSU gets shut down and TV remains in standby.(see also Why my TV does not start up and remains in...)

Try first leaving the TV power cord unplugged for some times, let say one hour or so. Then connect powr

If that does not work, and you keep having the TV in protect mode, it means that there is a fault.

In that case call the support number listed on Philips user manual to arrange repair.

If you are a technician I can try locating parts, service manual and giving more directions. Common faults that affect a Philips rear projections are convergence, PSU board, lamp and ballast assembly.

Regards.

It keeps flashing between flashing lights regards


Hi.

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.

Let me know when TV warms up does it go to standby?
If yes, standby light would be blinking, let me know how many times it blinks?
And if TV does not go to standby mode, does picture remain with red tone?

This fault can be caused by low secondary supply voltages often caused by the value of capacitors becoming low and requiring replacements but you will have to have a technician.

Grand Wega picture going on and off; standby light flashing, sound remains on


Is the cooling fan running properly?  I'm just guessing, but it sounds like it could be overheating and shutting off, which allows it to cool off enough to turn on and overheat all over again.
