Question about Philips 55PP9502 55" Rear Projection Television

9 Answers

Tv turns on but shuts right off

55PP9502 TV not working. When the TV is plugged in and is turned on, the power light on the TV lights up like normal. Instead of hearing sound and seeing a picture and few seconds later, the monitor remains off. Sometimes I hear some clicks in the back like it’s trying to turn on but then just shuts off again.

    I bought the TV on Ebay a couple months ago from a guy in Indiana. It worked great for the couple months and I really enjoyed it. I’m not exactly sure what’s wrong with it though. From what I read, it sounds like there could have been a coolant leak from one of the tubes and it got on one of the circuit boards. I’m thinking that maybe it started to leak on the car ride home from Indiana. We had to take back roads so that we didn’t go so fast, but they were very bumpy. To be honest, I had no idea that there was any kind of liquid coolant in those TV's until I read about it. That's what I think is wrong with it. Every blog and website says that's probably it. I don’t know if that’s the only thing either. So that's what I know.

    just wondering if anyone knows how much this might cost to repair

  • RyanV Jul 30, 2008

    I didn't mean to close this problem out, how do I "reopen" it?

    I still have to try the solution :-)

  • RyanV Jul 31, 2008

    how do I view more solutions? or keep this open incase the solution does not work?

    thanks again!

  • RyanV Jul 31, 2008

    if I have to replace the circuit board where do I get something like that? or would be it be smarter to take it to a shop?

    thanks!

  • RyanV Aug 06, 2008

    thanks, it turned out to be a coolant leak that damaged both boards, well over $700 to repair :-(

Take it to a shop is probably your best option.
However, you don't have to physically take it around to shops.
Call them first. 1) See if they service that brand of TV 2) Ask about availability of parts. There are some that it is difficult to get parts for. 3) Ask if they can do the service on-site or if your only option is to bring it in 4) See if they will give an estimate over the phone. Shops all have different markups on parts, and labor can vary. Some shops have a base fee, some don't.

Best of luck with this. Let us know what happens.

The TV safety switch is diagnosing an internal error (short, overvoltage, blown IC or capacitor) and is turning off the TV to avoid eventual further damage.
When is like that you need a technician taking apart the TV and testing components inside.
Check the last pages of your manual to find the Customer service telephone number, or take the TV to a local repairman.

    And recarding the fault, coolant leak is not a very common fault, more likely is a blown capacitor or IC.

FIrst of all, the click you hear is the main relay turning on and off. If a problem is detected, the set will shutdown. If a coolant leak is the problem, you should be able to see this quite easily by opening up the back and looking at the boards under the CRTs. If there was a leak it will be obvious.

To fix it requires perhaps a board change, but more importantly, a replacement of the fluid and resealing of the fluid "tank". Can you please examine the boards and let me know if there was a leak?

If there was not a leak, there are a number of things to check on that may be the problem.

Please let me know.

Hello,
The noise is probably the power supply in hicup mode or safety mode, that's what happens when a fault develops in the set which loads the power supply down. All you have to do is get a multi meter and go round measuring things like Resistance to earth from collector of line out transistor this should be at least 10kohm , then measure the various diodes that can be found in the power supply...Also check for any broken fuses...Try to replace them..Thank you...

Please post back on how things turned or for further assistance...

Regards!!!!...

You have a short in the high voltage circuit supply board, what ever the cause most likely the price to fix it will be more than it is worth, esp. if it is a projection TV, I found this out 1st hand.

Unfortunately it has nothing to do with the power plug.

If you turn it on and it works normally but then shuts down it's activating an internal protection circuitry to prevent damage to your set. It's not an adjustment, it's not something you can fix at home. Sorry to be the bearer of bad news but it will likely require a shop repair.

Solution is simple....

First, unplug power cable from the back of your TV. You will notice the flashing light is still flashing. Don't worry, go to the Second step.

Second, keep pressing on the POWER button, located on the panel at the top of your TV, to shut off your TV. This will stop the flashing light from appearing.

Third, Plug the power cable back onto your TV

Fourth, press the POWER botton ONCE, using the same button used in the Second step to turn your TV back on.

Fifth, you will see the POWER light comes on, as normal.

Sixth, using your remote control, press the green button to turn on. Your TV should work as normal.

Will not turn back on


Take off back cover. The problem power board is to the right of the board where the power plug feeds into the TV. There is a large white fuse right bend the power plug. With a meter it read ok; about 8 inches deeper into the TV on that board was the resister next to two fuses. My 4 amp 125 volt fuse did not read on my meter. After replacing, it worked fine.

TV auto shut off-power indicator light blinking-won't turn back on


You could have gotten an electrical surge that put your set into a shutdown condition and unplugging the set and letting the Microprocessor reset will fix this problem if it dosent blow out the main power regulator as you still or might I say have a regulator IC problem. IF THIS PROBLEM HAPPENS AGAIN MORE THEN A FEW TIMES WITHIN A SMALL TIME FRAME I WOULD HAVE THE SET LOOKED AT BEFORE THE REGULAOR BLOWS SOMETHING OUT!!!!
