I have a 32" RCA


Hello
According to you, your RCA TV has went off while watching it. As there is no sound or picture at all, and the power kicks, the fault must be to its horizontal out section. The horizontal output section have LOT [Line Output Transformer] and related parts in it. Your TV must be chcked well to detect the actua fault. Normally, the LOT said above can be faulty, otherwise, the horizontal output transistor, the device that drive the LOT may also damaged. If this transistor gets leaky, the secondary main power DC supply will get a direct short, and the set will come on protection mode as we switch it ON. Here, according to you, this is happening. Just replace the horizontal output transistor first and see the effect. It is a three terminal component, screwed on to a metal heatsink, and can be located very near to the above said LOT.
After replacing it, switch On your TV, for a while, say 5 seconds or so, and if a whisiling sound is heard, and the replaced transistor over heats, the LOT said above is faulty, and should be replaced with same type and number. OK.

I disagree with given info, this tv has no horizontal output transistor because it is dlp tv.
3 red light blink means lamp cover is not placed back properly after lamp replacement/ lamp checking. Make sure lamp cover is fixed back in its place securely and tight.

Flyback transformer and horizontal output transistor change out


There is a little loose sleeve at the transformer. It can be pulled out, but it is best to squeeze the sides through hole on each side of the terminal to remove the sleeve. The wire just comes out with a small pull afetr the sleeve is removed. Good luck.

First, locate the horizontal output transistor. This is found very close to, or next to, the horizontal output transformer (also known as the flyback). The flyback should be on an aluminum heat sink, or on the side of the metal chassis. Disconnect or unsolder two of the three legs of the transistor. Measure it with your meter, or plug in the set with the light bulb attached across the fuse.
If the transistor is shorted, or the light bulb doesn’t glow bright anymore, replace the transistor and plug back in. If the light bulb glows bright again, you must replace both the flyback and horizontal output transistor simultaneously. In some cases this will fix the set, but sometimes there are multiple problems with a set.
Go to where the flyback is, and start measuring the diodes and capacitors on the flyback itself. If you don't find any shorts there, it could be a shorted vertical output IC, a shorted sound IC, a shorted disc capacitor in the Hi Voltage/sweep circuit, or in rare cases, a shorted capacitor or tuner.Feel free to ask and post whatever the result of your troubleshooting..


Hope this may help;

The chirping is usually related to the horizontal output transistor or the flyback transformer or both. Let me know if you need further assistance.

WHEN i turn the tv on, I get some sound but the tv shuts down before the picture comes on. two seconds at most


Without the make and model I can not give you details. However, the TV is detecting a problem and shutting down to prevent further damage. The most common failure is of hte horizontal output transistor. This is a 3-legged part attached to a heat sink close to the flyback transformer (part with large red wire coming out the top). Try replacing the transistor first.
