Not showing picture or sound

its either a fan going out or power transformer. take the panel off and turn on the unit while being careful not to touch anything at all while power is to the device. plug it in and listen so you can identify the component. If its a transformer (it would more than likely be square and wrapped in a thick polymer sheeting.) it will be fine, possible for good. If its the fan making noise, you will typically have 9-12mths from the time you first here the sound before the perfomance is affected.

SO, to make a long story short, a hummming sound is typically the sound of electrical variations in a component, whining is normally a rubbing action within metal and plastic components.

(plastic on plastic makes a squeek, metal on metal a higher pitched squeek)

Hi,
Here is a tip that I wrote about dryers and noises...
It will help you determine what is happening there...

Asker's Testimonial " This should give me an ida of what to look for once I open er up

RCA Projection tvs are trash,should be off the market.

Sounds like the HV generator will need to be replaced. Can you tell if the sqeaking is coming from this component without touching it?

Replace IHVT (xformer) Part #259296

The power supply is telling you that it has a short. I think you have a bad high voltage transformer in the horizontal deflection circuit. I've repaired several RCA's with this very same problem. The newer RCA's are vert prone to high voltage transformer failure ! Stargazer

if you are having sound your problem is on the video circuit or related circuit.if no sound on video no power have your tech check the power supply and related circuit.good luck.

I'm having the same exact problem with mine! I'm looking for a solution also. I opened up the back of the TV and blew out the dust. Then I checked all connections. I put it back together and plugged it in. Now it doesn't make the high-pitched squeeking sound, but I still don't get a picture. My guess is the picture bulb is burnt out. I'm trying to find one online and am planning to fix it myself - wish me luck!
