You have an intermittent connection, or a "Dry Solder Joint" or perhaps a Plug that is loose.. These can be real hard to track down. You are going to have to take it in for repair to a reputable repair.Service center. Get a firm "Quote" for repair.Shouldn't bee too costly though.

Tv isnt turning on, you will hear a click then see the power light flash 6 times then the light goes off for about 10 mins then comes back on flasing again...and the cycle just continues. It did this once...


Sounds like a power supply problem. I worked for a short period for Panasonic at their USA plasma R&D / small scale manufacturing facility and learned that to "ignite" or start the plasma when turning on the set, a significant current discharge is required.

The recycling seems to indicate that the "brain" in the set realized that a plasma has not been established, and it is attempting to recharge the starting circuit. The flashing power light is probably significant and a trained technician or a service manual will probably identify this as a trouble code pointing to the problem. Sorry, I did not have any exposure to the finished product and cannot advise what the code means.

If the set is still under warranty, you should act immediately and get the problem taken care of, because it will not go away on its own, and will most likely get worse. Sorry the news is not better. Good luck!

TV will not turn on


Sounds like the power supply needs replacing.

TV repair is best done by a pro unless one has significant experience with it.

Having the yellow flashing light


Sounds like maybe a power surge killed the TV. If it is newer, try contacting the Manufacturer for warranty repairs.

HL-P5063W vibrating and won't turn on


i have had this happen to me several times in the field, and if it is what i think it is, you are not going to be happy =(

inside of a DLP type TV, there is a device called a 'color wheel'... it is essentially a disc made up of different colored glass that spins really fast. this disc has 3 or 6 (depending on make/model) pieces of colored glass like pieces of a pie affixed (read: glued) to a hub.

what happens sometimes is that one of the pieces of colored glass flys out of the hub, and causes a massive unbalance in the spinning wheel, which causes the hum/vibration, and since the colored glass is missing, the colors will be all messed up.

if this is what happened, then your television will require a new DLP engine.
