3.0 OHV engine?

This is going to sound wierd but with the engine running and the noise preset stand in front of the vehicle and put your forehead on the intake manifold. If you hear the squeak in you right ear than it is the CMP shaft making the noise. Over time the bushings in the shaft wear out and the shaft will squeak and sound just like a belt squeak. eventually it will get bad enough that the engine will start to hesitate if not stall.

The easiest way to replace the shaft is by removing the upper plenum. The reposition the harness exposing the shaft/sensor. It is located on the drivers side of the engine right below the throttle body under the wiring harness that runs by the rear valve cover.

The shaft and sensor are available in the aftermarket.

The shaft is similar to a distributor shaft and will need to be in proper alignment. I can give you more detailed instruction if you decide to replace it yourself.

Please try to switch the TV on with the help of Remote control when the stand by timer is on. Also get the On/Off switch checked up. It may not be making contact because of loose spring. You may have to get it replaced. Since your stand by timer is getting lit that means the power is coming to the set and the safety fuse is OK. The switch is not making the contact.

Check the power supply module for bad caps, Q7,and ZD4.

The squeeking sound could be the high voltage trying to strike the lamp, it will try several times to strike the lamp then shutd down. Take the bulb out and see if it s blown. Even if it is not blowen it sounds like you have a bad bulb.

is there a cadence to the blinking timer light?

turn tv on picture comes up 2to3 seconds later tv blacks out then stand by red light flashes 4 times in a row repeatedly..can not turn on or off when stand by light starts flashing but before tv blacks out you can turn tv on and off repeatedly and picture and sound work.You have to unplug power cord for 30 seconds after stand by light comes on to get tv to turn on.

if you are comfortable taking the back cover off, do it and visually inspect a cylindrical shaped components on the power supply unit... if you can send a picture please do [email protected]

THIS SOUND LIKE A FAULTY START SWITCH OR ON/OFF BUTTON WHICH IS COMAN TO GO ON TVS

Sounds like the HV generator needs replacing. You can get a replacement at the following link. If your not sure which one your model uses, leave them a email with the model number of your set.
