Question about Televison & Video

1 Answer

My 7 year old Phillips 42" plasma has started to go blank - with the red light on the side blinking. Only solution is to manually turn off the set, turn it back on - red light constant - then turn it on (green light). This works for a minute or two, then the same thing all over again. The frustrating part is that it happens intermitantly - usually at a very inappropriate time! Sometimes it won't happen for days - other times it happens every two hours.

    No external power supply. Happens when it's cold or hot - doesn't seem to matter.

    Probably you need to replace the power board, also the main board can be cause for the problem.

    When it gets hot after a while some defective component fail, and TV goes blank.

    The TV should be tested by a technician, and the defective part replaced.

    If you decide to call a technician you can use the number listed on the service manual.

    Here you find all the parts for your TV.:42FD993517

    Power supply board is $239 POWER SUPPLY, main board is over $1000

    If it is the power board , or the main board, this can also be repaired replacing bad components, for this reason is better to take the tv to a workshop or to call a technician.

    Also contact Philips calling the number in the manual, and ask if they can sell you a warranty extension.Otherwise see here :Get a Warranty Extension

    And get the repair covered with the extended warranty.

Having problems turning on 2 year old Phillips

Philips TVs tend to have issues with bad capacitors in their power supplies. Failing capacitors tend to have slightly different ESR (equivalent series resistance) values when they have been left off, versus after they are warmed up and charged up. Either a new power supply board or replacement of the faulty capacitors will fix the problem.

Phillips 42 In Plasma Blinking Red Light Only

blinking link means there is a problem with the software -- usually this is caused when a fuse goes bad or the power supply board needs to be replaced due to a problem --- most repair places replace the whole board - nobody fixed one broken part
