Sounds like a slightly defective or intermittent relay, need to get it replaced (the relay)

ALL TVs still use relays

I can’t be certain due to the vague description fo the problem and no model number but it is likely a bad capacitor to the power relay. I have a a few models with that same problem. Mos tof the newer ones now dont even use relays anymore.

Hi, without knowing too much about the model etc, my best guess as an ex television engineer would be the clicking noise that you are describing i would say in the televisions power supply (inside the set) They normally have what is called a switch mode power supply which unlike the name has no mechanical switches. It relies on various electrical components. If it is intermittent as you say my guess would be a dry solder joint or maybe a capacitor either are not dear but sometimes locating the faulty part can take time.

Depends on the model.
The description of clicking and screen flickering with a DLP could be the color wheel is off axis.

CRT RP: Would be power issue.

LCD RP: Could be the lamp.

It might be the wall outlet. Try plugging it in a different one if it still acts the same its probably the television set that might have a bad power supply.

Comment on how do you clean a rear projection television screen? by Sphinx

Here’s a bit of advice I received from a professional TV calibrator - First blow the screen clean of visible dust with compressed air, that canned computer duster stuff being perfect for the job. Once complete use a lint free type of material such as a cloth baby diaper(preferably unused) or a soft piece of flannel and warm water mixed with a mild detergent such as dish washing liquid in a VERY diluted state. Wring out the excess water till barely damp then apply to the screen but NEVER scrub, instead use an up and down motion with gentle pressure until clean, then dry with a cloth of the same material.

This is how he cleans each and every TV he calibrates and has for years with great success, plus it’s hard to argue with someone who earns his living doing such. Oh, as a last bit of cautionary advice make sure you avoid any and all ammonia based products such as Windex as they will do irreparable damage to your screen. Hope it helps, good luck and happy viewing

Comment on I recently got a Mitsubishi WS-55819 55 in Rear Projection Television and I can’t get any picture or sound at. by TV TECH-man®

I don’t know….did you get it out of the garbage?

That’s never a good indicator of repairability…

No picture and sound could be a $300 to $500 repair job for a TV tech…..

Comment on Can projection television be made small like projector, and can be viewed on home screen.? by grizz

YES it is possible but it really depends on how much soft ware is used in it and also the excact size you want to make it.
