There are actually 3 light guns (or as you were told, "light bulbs") in your projection TV, and if one of the guns was failing and making the noise, you only had a one in three chance of fising the problem if you replaced only one "light bulb".

i have seen this before and sorryy to say if unplugging for 5 or more min and that dose not fix it may need to be replaced not many people fix them these days but not impossable

There is no LED on a rear projection television. There are three projection tubes (RED GREEN AND BLUE) and those tubes are mounted in the set and project the image to the mirror and then to the lenticular screen. The issue with brightness could b one of several things. Dust and film accumulate on the tubes and mirror. This causes the image to fade, Also since it has TUBES they age. They are getting hard to find too. The other thing is the adjustments on the set can change over time. There are brightness and contrast settings inside the set that have to be changed and reset after long years of use.

Here at my shop we see this problem with these rca sets. The processor is seeing a command from the keyboard or the ir sensor. The most likely cause is a faulty keyboard cuircit board. And replacing is the best coarse of action. To make sure its the problem I remove the keyboard cuicit board and see if the problem goes away. I just use the remote to control the tv, u can also do this until the part arives To get the part you need to know the entire model number. It will be on the sticker in the back in small letters hd52w56yx1 or yx30 or something to that extint. i get most of my rca parts from union electroncs or just let me know and i can look up the part number for you

hi'

is the line horizontal or vertical ? you have some sort of a deflection problem its either vertical failure or the yoke return circuit on the horizontal has a failure

its setting the screen format . take the factory remote and by using the cursor left or right you can scan the size changes

This is a CRT set. Likely no HV, maybe bad flyback. . Possibly bad capacitors on SMPS area of deflection board too.

May have a pincushion issue is not adjustable, or programming set to one specific size. Sometime this does occur with digital programming.

Your backlight went out. Manual should tell you how to change it
