Question about Zenith A32B86R 32" TV

1 Answer

No Picture Hi, Last night the tv started making a high pitch sound and the picture went out. Smoke started coming out of the cabinet. This morning I opened the cabinet up and plugged the unit back in, same high pitch noise and no picture and I guess it is a resistor that is smoking? It is oval shape and the color is black.

Re: No Picture

Rarely picture tube also shows the same symptom. High pitch sound is due to through deflection area LOT power supply is loaded. Compulsary horizontal output transister short. From your statement i think Lot puncture takes place. Change LOT and horizontal output transister and check tv is now working.

Was working fine last night ,went to turn it on and you can hear a buzzing by where you plug in your jacks a bee,or high pitch has no picture or sound.only sound you hear is this buzzing

Sounds like your power supply is causing the problem. Unplug the TV wait 10 minutes, look in the back for a red button (circuit breaker) push it in. If this does not work you have a low voltage power supply fault.

Your TV have faults on Horizontal deflections, the oscillator and the Flyback might be the problems. If you are not familiar with TV circuits?... call tecnician to check your set.

if you can get another one for a reasonable i would certainly consider that. the cost to get these lcd's fixed sometimes is not worth it. you seem to have more than one problem with the set.

10-year-old 32" RCA PIP TV just blinked off one morning after about 30 minutes. It makes a continuous high pitch sound, and the on/off switch is completely unresponsive. I assume this is a picture tube and...

It's not the picture tube(especially if image was good b4 it went dead). The high pitch noise is the power supply whinning because it's shorted or overloaded. I just fixed one of these sets - replaced the horiz. o/p transistor and flyback estimate around $120.00-$160.00

Stopped working and squealing sound

Your set is shorted circuit condition. The power supply is making the noise. Unfortunately almost any of the hi current circuits will do this. If picture went out 1st look for video or hi voltage problems.
