Our tv worked fine yesterday afternoon and we went to turn it on last night.
The screen is black and it is making a loud clicking, crackling, zapping sound. Is there anything I can do? Thanks in advance.

Re: RCA 35" no picture, clicking zapping sound
What you are hearing is the discharge of high voltage which if it hasn't already failed, will fail if allowed to repeat too often.
The only thing you might try after unplugging the set for a minimum of 24 hours, is to remove the back shell (shouldn't be more than 8-10 screws around the perimeter and perhaps one or two around the connector cutout) and with a clean paintbrush and a vacuum cleaner with the nozzle held close to the work area, brush the CRT (picture tube) free as possible of accumulated dust, paying particular attention to the area around the large rubber cap with a cable leading to the circuit board.
I can't stress enough that the set must be ignored to allow the 25,000 plus volts that are present on the CRT when operating are given a chance to 'bleed off.'
This voltage doesn't often kill anyone since it is a short-term discharge with the set off but I have seen it punch a hole through a thumb.
If you are lucky, the horizontal circuit is not in its death throes but only discharging through a layer of typical household crud.
Unfortunately, this will not likely help you and you will require a tech to locate the problem.
Good luck finding one that isn't dead or retired yet; we are dwindling.

Sounds like a failed vertical amplifier circuit. This is normally primarily contained in an integrated circuit mounted on a heatsink.
There are other possibilities along the line but the one above is the most likely.
Now all you need is a TV repair shop that is still in buisness.
Try unplugging it for a minute. You will have to go through setup again (most likely).
Some of these sets have a (software?) issue and the audio drops out maybe once or twice a year-at least that's what I've experienced. No real fix for it.
Rca has been known to have bad solder joints in the deflection circuits. Usually around the flyback and transformers.. check it over real good. Just be careful as you can still get shocked after the powers removed the capacitors and picture tube will hold a charge in them.
Hey Jim, The high voltage protection circuit has gone out on the D-board and will need to be replaced. The fuse to the power supply is probably fine. A good repair tech shouldn't charge over $125 for this and it only takes a couple of hours. Let me know if I can be of further assistance.
