Most times client forgets to re install the access door to the lamp after replacement, but if you think the fan is bad try using compressed air and blow it out 1st with the set off. Recycle the ac. ( unplug set then replug it back in)

if you purcased a LTI lamp then the possibilty of a bad lamp may be the case. LTI lamps are cheap and are poorly manufactured. if it is a JVC lamp then you may have further problems such as lamp balast, or thermal sensor. clean the fans and filtersfor better air flow. keeping the lanp cool is important for the life of the lamp.

Refer to your prior post for answer.

It is hard to say what the problem could be. A lot of boards on this unit can cause the same condition. Lets start out simple. Can you get the menu to pull up? If you can then check your connections at your inputs and at the components that you have hooked up to the TV. If you can't bring up the menu, then I would suggest having a servicer look at it. You could have a bad tuner causing this, a bad digital board, bad analog board or even a bad light engine. To many variables.

You need to replace the screens. Call JVC with the model# of your set and JVC will tell you the part# so you can ordere a replacement

This model did have problems with : missing color (red,green or blue) and other issues like inverted picture-----it may need the main cpu reprogrammed which is done with a jig and two sd cards loaded into the set that way.

Had this happen on a Comcast box (Motorola DCT 6416 III)
Here's how to fix it:
Turn the cable box off, leave fully connected. Press Menu on the remote
The cable box internal menu will display (Not the Comcast one the Motorola one-- i.e. Display ratios-16:9 etc It's in black and white)
Use the arrows to cursor to the Closed Captioning and toggle to "Disabled" Press Manu again to exit and Voila!

Power the box on an have at it

The main one is located inside the set where the power cord goes, follow the cord inside if you are able to do that.

They must have meant picture tube, a rear projection set has three picture tubes. One red, green and blue. One tube cost probably $150 - $250 and are not that hard to change but doing the necessary convergence adjustments can be difficult especially if you have not done them before. One thing that always makes it a difficult decision is when you put one new tube in will the other two still be in good enough condition to get a good color balance.

blinking light indicates that some thing is wrong inside the tv circuitary. may be any IC of any other component is short & not letting the power supply working. if you are a technical expert of tv you can cold test the power supplies for short circuit. or you can call a tv repair expert.

The old lamp was in there before the fan work?U replaced the lamp u put the door back on did u make sure the safety latch is off and tightly closed with the the lamp door.The continue blinking LED light does it make alot of clicking noises too.Yes,then the Ballast board it is dead too.The Ballast board only job are to help the projection lamp to ignite to work.
