Have a wiring issue this car was hit in the front and now my head lights dont work bulbs are good but wont turn on with the switch

Check your fuses first off, then look for any damages or pinched wires. If the wiring look good look next for a bad or missing ground. A good test lamp or better a Power Probe will help you trace power and ground to and from your lights to assist in fixing the issue. If a reputable shop did repairs on it after your wreck I am sure they would stand behind the work and fix any issues related to the accident. If all these things check out test the headlamp switch. Good luck

The engine will not turn over?

If the engine does not crank when you turn the key you must diagnose what part of that system is faulty. Check battery terminals for corrosion. Clean and tighten as necessary. Are the headlights bright? If not have battery tested. Then check fuse bock for blown fuses. You can have starter tested at your local auto parts store for free in most places. That would then leave more difficult to test things like the neutral safety switch relays and the starter switch. Good luck.

How do I test the y-sustain main board from a philips plasma model is 42PF7220A/37 the Y-Main sustain number is LJ92-01200A....both buffers tested bad but now I dont know how to test the y-main...i...


As such boards are cheap and fail quite easily (both the two sustain and the buffers) Philips service manuals are more oriented at board swapping then at proper testing. In this particular case the buffer boards fail very easily because of a bad soldering to IC. The short will regularly blow the main sustain board.

To start when a main sustain (e.g. Ysus) is fried the TV will go in protect mode with the led flashing in standby. One test is done disconnecting the Sus board (with power off) and restarting the TV. If TV does not go in protect, then the sustain board was good.

If there is no protection:

The first thing to check on a main sustain board is the fuse. If the fuse has blown the IC is probably fried.I believe fuse is F5004. Check for swollen capacitors that may have blown. Test the FET. That is the core of the board as it is the power amplifier.

Here the service manual:PHILIPS_SM_15540.pdf - Right Click "Save Target As"

Here a more useful service manual. Check and follow troubleshooting diagrams in manual.

Here some troubleshooting from users.

Note:if buffer board was shorted, then the main sustain board is usually faulty.

Have 2005 yamaha roadstar wont start no power. Batterie and fuses are good any idea what would cause this

Here are a few things to try to help you diagnois your problem.
1.Check for corrosion on battery terminals and the fuses.

2.Fuses are good - Did you check the fuse on the top of the solenoid?

3. Take a screwdriver and jump the solenoid wires to start the engine. If it starts, then your starter is good. (could be a bad solenoid - but lets check some wires first)
Your solenoid operates when you hit the start button.
Your start button won't work until you turn the on/off switch on.
Your on/off switch only has power when you turn the key on.
4 Use a test light to test the following:
Right Handlebar switch house - Test to see if you have power to on/off switch - Turn your ignition key on & off to see the testlight come on - if light comes on that means your igntion switch is good. If no light, the problem is in the igntion switch. or the main fuse to the igntion switch is bad.

If the light came on then you have power to one side of the on /off switch - test the on /off switch by turning it on and off. When switched to on you should have power to the other side of the on/off switch which is sending power to the rest of the bike which includes your starter button.
Test your start button with the test light by putting the test light on the solenoid - Turn key on - turn on/off switch on - push start button and see if the test light lights up. If the test light lights up that means that your solenoid fuse may be bad. It is located right on the top of the solenoid. If the fuse is good then that means your solenoid is bad. Replace it with a new one.
If the Test light did not come on then your starter button is not making contact and needs fixed or replaced.

So follow the power with the test light until through each component until you come to the faulty one.

NOTE: If its a blown fuse, check your wiring. You'll have to find out why the fuse blew and fix it or your fuse will just blow again. Could be a short somewhere, installing a battery wrong will blow fuses.

The lights wont turn on and the gauges on the dash board aren't working either what wrong with it?

Well, the first thing to do is check all the fuses first, make sure to check the fuses in the engine compartment also,then if all fuses are good then the next thing to check is the switch, make sure the connector for the switch is connected good and tight, then i would look at the headlight switch next, for this a test light is need to check for power and ground,make sure theres power at the switch and then as you turn on the switch it sends power out the switch. start with these tests, hope this helps,

The gauges for my speedometer,rpm,gas tank,temperature stopped working I know its a bad fuse but I dont know which one because I lost my owner's manual

Check EVERY fuse. Use a 12V test light. Take the test light and clip it to a metal part of the car and test each fuse with the tip. If both sides light up the light, the fuse is good. If only one side lights but the other side doesn't, the fuse is bad. Fuses are made to be tested like this. With a test light, it will maybe take 1 minute to check every fuse. If all fuses test good, these instrument panels had issues with bad solder joints.

Sony KV-32S45 32"color won't turn on

If you know all the saftey aspects about tv repair then your gonna need some special test equipment to troubleshoot this set. There are no real user serviceablew parts inside this tv as they are all soldered in and you cant tell by looking at them if they are bad. Theres lots of hi voltage inside these sets even afterv they are unplugged for awhile. if you know all the saftey issues your gonna have to first disconnect the horizontal output transistor and measure it with a good ohm meter. If it measures bad ythen order a hi voltage transformer and replace both at once. If you dont have this equipment or know how to unsolder and solder then you should call in a pro to assist you with this repair. Good Luck
