37PF9731D/10 Philips TV. On / off button seems to be moving "in" to the TV, making it difficult to switch on / off. I don't want to send it back to the manuf. as it will be gone for 15 days - is there something I can do to fix this myself (internal screws etc.?)

    It only has a couple of months warranty left on it, hence the reason I was asking about effectively a home repair ............. 15 working days is a long time without a TV for something I can potentially repair myself.

  • andypender Sep 01, 2008

    Do you know what type of fixing arrangement this type of TV / power switch has ........ the switch effectively seems to be physically moving in to the TV - still working OK just now, but if it moves much further, I won't be able to switch it on / off.

  • andypender Sep 01, 2008

    Many thanks. Much appreciated. I thought it would be a shop fix, but worth a try anyway .....

The switch button is already loose contact or crack solder joint,thats why its hard to turn on / off .Its needs to reworks the solder joint or resolder it, so it will works normally or replace the switch with a new one.Find a TV repairman to do the works or bring it to a shop,find a good one ,its cost you maybe $50 to $75..

Hope his may help;

It may fatal for you and for your tv by doing all by your self. it will take much more problem if you handle this one. so i suggest that you should send it for a service or repair with a technician.
if you still insist of repairing it by yourself then try this one.

  • Consult your TV’s troubleshooting guide. Follow its recommended steps. Most problems can be fixed by troubleshooting.
  • Diagnose what's wrong with your TV. There are many TV repair tip websites on the Internet you can consult, like the "Notes on the Troubleshooting and Repair of Television Sets" website (see Resources below). Or, try asking a TV repair question on an online message board like AllExperts.com (see Resources below). You can also find books on troubleshooting projection TV's. Check your local library or bookstore for a book like “Complete Projection TV Troubleshooting and Repair."
  • Get your TV’s service manual to find a diagram of your TV’s circuits. You can get a service manual through a retailer that sells your TV brand or through an online store like tvdiagrams.com
  • Gather the necessary tools. For most projections TVs you'll need a Phillips head and a flathead screwdriver to remove the back shell. You may also need a digital multimeter to test the circuits
  • Know the common problems and fixes for a projection TV. Below are a few common problems that people come across when a projection TV goes on the fritz.
    • Blurred, snowy picture: Turn on your projection TV and wiggle the coax cable from your cable box or antenna where it connects to the TV. If the picture fluctuates, you know that you have a loose connection, or that the coax cable is bad.
    • Blotches of color on the screen: Caused when your projection TV becomes magnetized. Use a strong magnetic coil and make circular motions around your projection TV screen starting on the upper left corner. Increase the size of the circles you're making until you've covered the entire screen. Slowly move away from the screen; continuing to make circular motions with the magnet. When the magnet loses contact, the color blotches should be gone.
    • TV shuts off randomly: It's usually caused by overheating. Remove any heat-emitting objects or anything that may be insulating the TV and causing it to overheat.
    • Speaker emits static: Follow the remaining steps to replace a speaker
  • Unplug your TV’s power cord from the electrical outlet and disconnect any peripheral devices like a DVD player or cable box. Place your television screen-down on a soft surface.
  • Remove the screws that connect the back shell to the rest of the TV. Then pull the shell up and off the TV carefully. Set it aside.
  • Consult your TV’s service manual to find the part that you need to replace or repair.
  • Place the shell back on the TV once your repairs are finished. Replace each screw to secure the shell to the TV
  • Plug your power cord back into the electrical outlet and test your TV. If your repairs weren't successful, it may be time to consult a professional
Ive got this info. from a site that would help you fix your tv. i hope that this steps would help you

cheers

You would need to send it in for repairs as it is if you do anything to the tv it will void out any warranty you may have on the set.

Check first the power cable.
Check the power button internally is working.
internally there is a fuse or circuit breaker, on the poower supply board near to where power cable hook up, check it out.
Tryu a different socket.

    If you want to do it yourself, disconnect the TV power cord one hour before taking TV apart, this eliminate the risk for heavy electrostatic discharges.
    Iside TV try not to touch circuits and components contacts with your bare fingers, some IC is very sensitive and can blow.
    And, as usual...DIY at your risk.

It sounds like a heating element has gone out, you have seriously hard water that has damaged the system or you have a burned circuit. Without doing something I would not recommend with that type of system your only real choice would be to send it back for repair. If it is brand new it should have a 1 year warranty.

Neither the hand-held "clicker," nor the buttons


To be absolutely sure, I would need to know the model number/name near the handle. If it is old as you say, it is probably a broken Cycle Solenoid LINK. If this link breaks (it happens A LOT on older projectors) the cycle function will not work. This is a pretty difficult repair and subsequent adjustment. You can still get the parts online at: www.microtools.com I believe they send install instructions with the parts. If you don't feel comfortable with the repair, you should contact an authorized warranty service dealer. Good Luck !

I have the SD790 IS, and the zoom button seems to be stuck/sticking making it very difficult to get the camera to zoom (or playback to zoom) however, when it does, it "jumps" to where it wants to...


The SD790 has a problem with the power button and sometimes the zoom switch, thankfully they are on the same assembly. You can get a new part for $35 incl shipping, or have it installed for just $30 more.

Another design flaw of this camera is:

If you haven't checked the screws recently on the handstrap side of your SD790 to make sure they are tight, I would advise doing so. Actually, take them out and secure them with Locktite, because if you don't they will fall out and the whole side of your camera will fall off.

If you need the zoom switch replaced, I happen to know the shop linked below would check and secure your screws for you at no additional cost!

37PF9731D/10 - when turned on the tv power light remains green but no picture or sound. Just a clicking sound - like it does normally when swiching on from being on standbay. It reapts the attempt to turn...


The clicking sound is from the main power supply relay being turning on and off, it is driven by hte main board and it gets the power from the standby power supply board.
You need to check the main powwer supply board and the standby power supply board voltages.
Check the resistor in the main power supply board also

Model 37PF9731D /10 tv cold starts up but after a while the speakers start making a constant pop pop pop noise it sounds like a dripping tap constan


It sounds like a bad capacitor on the audio board or the speaker themselves are the problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
