I ask this because I once had a Bouvier/Briard cross, and once, a hair of his got stuck in front of the lamp.
Try turning the TV off, and using either compressed air or a vacuum, try to stir things up around the lamp compartment (though be careful not to knock anything around, or if using compressed air, don't aim at any components directly).
Buy another HDMI cable an tried it out maybe the cable it bad.Tries the cable box with an colaxial hook up see u get the same result,could be the cable box it bad.All these thing are test,all things are good.Than the tv Tuner signal board is bad.Tries website like Shopjimmy.com,Ebay.com to buy a refurbish Tuner signal board for the replacement.
This problem sounds like it could be one of two things. It's possible that you have a bad Lighting control Module (LCM) or a dirty, worn or faulty turn signal switch.
Is a microprocessor based module that controls several vehicle subsystems.
Responds to electrical input signals from various switches, sensors and external modules.
Is located on the LH side of the instrument panel.
Subsystem functions include:
Headlamps with auto lamps.
Turn signal lamps/hazard flasher lamps.
Daytime running lamps (DRL) .
Interfaces with the Driver Door Module (DDM) for illuminated entry and anti-theft systems.
A scan tool can be used to diagnose if this is the problem. Turn the ignition switch to the "On" position and set the front wheels to point straight ahead.
Turn the ignition to the on position, (Don not Start) And straighten the wheels. Make sure all the accessories are off and place the ignition in the OFF position. Now locate the Restraint Control Module fuse in the fuse box and remove it with a pair or needle nose pliers or a fuse puller. Once removed turn you ignition to the On Position and look to see if the Air bag light stay lit, if it goes out you have removed the wrong fuse. Now under the hood, remove the ground (negative cable from the battery) and wait at least 2 minutes for the power to diminish from all circuits.
Replacing the multi-function (Turn signal) switch is fairly simple. The steering column cover needs to be removed first. It is in two halves, top and bottom, and the screws are accessible through the bottom. There should be four of them - Philips head, recessed about 2".
To make it easier to separate the two haves once the screws are removed, it helps to have the tilt-wheel dropped to a horizontal or slightly downward position.
Once the cover has been removed, ( If air bag equipped) You will need to remove the air bag using a socket and ratchet, lift the bag slightly to reveal the electrical connections and remove and mark them for ease of installation. You will now need to remove the signal arm by unscrewing it. You might find that you will need to use a piece or rubber and vise grips. It's tight, and the rubber, rapped around the switch arm is there to protect the finish when using the vise grips. You'll see the mounting for the switch and the wiring harness connectors. The replacement should be fairly obvious at this point. There should be another four screws/bolts that hold the multi-function switch assembly to the column (two on top, two on bottom.
This could be multiple things. If the fuzzy picture is on your regular cable channels and the tv is hooked up directly to the cable then it is a signal issue. Your cable signal is probably too low because it is either split too many times, a splitter went bad, a piece of cable went bad, you have RG-59 cable rather than the much better RG-6 cable. Another solution is if there is a vcr hooked up, the cable jack on the vcr could have gone bad, the vcr power could be on which will cause a fuzzy screen. If you have a vcr try to bypass it and hook directly to tv. If that fixes you problem then it may be the vcr or the wire from the vcr to the tv. If you have no vcr then I recommend buying a cable amplifier and hooking it up. This is a band-aid solution but it could work long term if it's just a matter of weak signal. If that does not fix your problem I would recommend calling a cable professional to evaluate your problem. Could be the line from the pole to your house or any of the wiring in your home.
It must be overheating problem . Check the fans . If the fans run properly , then you need to check the fuse or the power PCB [printed circuit board ] . If everything is okay with all of those , then I recommend you to replace the bulb .
Here I'll tell you how to replace it :
Make sure that your power switch is off and that the power cord is unplugged from the electrical socket. It is also wise to unplug any other cables and label them in order to restore them in the right way once the lamp is replaced.
In order to see the lamp, remove the access handle on the outside cover. You may need to use a screwdriver.
Pull out the used lamp and clean the relevant parts using micro fiber products and not paper. Please note that in some projectors a small inside filter should also be replaced.
Insert the new lamp into the projector carefully avoiding touching the glass of the lamp itself. Touching the lamp will deposit skin oil that will likely damage any new lamp during use.
Reassemble the access panel, repluge the cables and power up the projector.
To get a good signal on all TV units, the source must be good and strong. The source could be an aerial antenna or connection to your local cable provider. The message "No Signal" indicates that the TV cold not receive a decent TV signal. With this in mind, possible solution wouold then be to increase/improve the incoming TV signal:
if you are using an aerial, 'height is might' to overcome any line-of-sight obstruction. Additionally, there are antennas with higher gain, meaning they could receive better than other antennas. Another option is installing a pre-amp or commonly called booster;
if you are hooked to a cable provider then it may be to your advantage to bring this concern to their attention. They could try transferring you tap off point to a better distribution box, replace your coaxial cable with low loss or even in some cases, install an inline booster;
possible RFI (radio frequency interference) which could come from wireless phones, garage door openers, WiFi, electronic dimmers, electronic ballasts of high density lamps and others. If any are present or within the immediate vicinity, pls try to relocate or reposition.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
