Have RCA 31" tube TV. Won't turn on anymore, and just makes a high pitched squealing sound. The sound seems to come from a transformer, which is supposed to be a T4101 X mode transformer, which is soldered...


Probably not worht fixing , I would hook it up to check the transformer before I amde a mistake giving you a wroung answer, But if the transformer is making noises like you said that would be the first I would look at as well. But to tell you its bad would be shooting myself in the foot. I would tell you this the repair of a transformer $120 bucks. Now is it worth the fixya probably not. 9 times out of ten here something could have killed the HVAC transformer.

Thanks I hope this gives you some advice please do rate it with the thumbs above.

RCA TV 32V434T transformer?


When the HVT goes out, it will take the HORZ output, in short, you will hear a high pitch noise for a sec, when pluged in. As to your question, Its not a hard repair, however its not what I would call a begainer repair. This is what make the high voltage (about 32,000 volts) for you set to work. If you DO try it, becareful. And don't forget to change Horz output p# 274762. After changing the parts, unit will not run for more then 10 seconds. You have to use a volt meter and set the G2 for 290v, with no signal and blue screen. + or - 5 volts will cause unit to shut off.

Flyback transformer on television


Single white line across screen mean a vertical colapse. So you will need the vertical output and maybe a cap around 100uf@50v.

Repair shop says Flyback Transformer needs replacement


If you know what you are doing, and you have a good (de)solderstation, you can repaire it yourself, but you don't know if it for sure the transformer. since you did not find the problem yourself, suppose you replace the transformer and your TV does not work !? Even when you repair it yourself, the repair guy shall charge you the cost for his time (I don't know the exact english word for his time checking the TV). And I suppose there is a warranty for his repair. So...
