Enter the tip of a pointed knife between the left side edges of the connector (circled in black in the attached pic) and gently tilt the knife away from the connector. Do the same on the right side. The connector should pop up.

A fuse is not your problem. this TV has a safty feture that when it senses a problem it cuts the power to prevent any fouther damage, when you un plug it the TV resets and it will turn on agian. I have the same TV Check the CRT light guns there are 3 of them. If one goes bad it will cause your problem.

Might be convergence problem if looks like at all the attached pictures---I have instructions for this repair and parts cost is not high--about 30 dollars.

All fillament based lights will dim as they age. Some of the newer/better types it will be unnoticible.  If you are losing image quality or brightness you may have a bulb that is nearing the end of it's life cycle.  A glance at you owners manual or the manufactor's website should give you an indication of the expected life of your bulb.  Also most of the projector made in the past few years have a counter that tallies the amount of hours your bulb has been on.  A more likely culprit is probably dust accumilation somewhere inside your projector. Most projectors have filters these days and need to cleaned at certain intervals and in certains ways.  Not cleaning these filters can cause heat build up that can increase operating temps and shorten the life of your bulb and or projector.  Or sometimes jsut fail and cause a dramatic decrease in image quality.  Again these things are vendor/model specific so you will want to check with them about your particular model. Hope this helps.

the blinking power indicator is actually a error code. How many times does it blink as I can assist you if you let me know how many times the led blinks

I would double check the wire connections especially the bridged connectors that connect the A and D boards also see if the wire from the front panel PCB is actually hooked up. Often its easy to get a wire plug mixed up and plugged into the wrong socket or not seated properly.

Problem is called convergence; see attached photos.

This set uses 2 of the STK-392-110 convergence chips, both will have to be replaced and total parts cost on EBAY will be under 25 dollars.

The good news is I have start to finish step by step instructions for this repair in this set. They tell you everything you will need and exactly how to do it.

They are based on my experience doing this repair in hundreds of sets just like yours.

I will enclose also a photo of what the chips look like.

If you want the instructions let me know and we will find a way to get them to you for free.

Check the power light for blink code--usually if this model shuts down the power light will blink in a sequence--3 blinks a pause and 3 blinks is short protection--usually means a convergence circuit problem.

Let me know what you find--I am here to help.
