Sylvania SRT2232S 32" was working

Remote sensor can be tested with set powered up--usually three leads where it is soldered in---with a meter one is voltage, one ground, one signal----check for the voltage with a meter but a scope is needed to test the signal.

Hello
The LOT [Line Output Transformer] of your TV. It should be replace with same type and number. Actually this is a skilled work. You have to unsoder this component out from the circuit board, and to resolder the new one in place. Have to adjust the perfect screen and focus voltage. Screen and focus voltage controls can be seen on it. This component can be bought from most of the electronic spare part shops at your tow. The number printed on it is important and should be noted. The sample picture of that component is attached here. This component also known as Flyback transformer. OK.

Hello
There is a fuse inside the power supply bard of your sylvania TV. Check whether it has blown out. If bllown out, replace it with same type bothe in size and amperage. If the newly inserted fuse also blow up as soon as you switch on the set, make sure that the power supply section has some short circuit in it, and should be cheked well. OK.

Hello
Without its remote control, you can't unlock this TV. Get into this link from where you can buy it.

OK.

Hi
Remove back fron tv locate line flyback transformer
on this transformer there should be two adjustment controls very carfully adjust the bottom one, do not adjust to far as picture will have fine white lines on it

Had same problem Sylvania SRT2232s 32"had to keep powering on and off until it warmed up enough to finally stay on. Problem was the 100/50 & 1/50 filter cap took it to local repair total cost to fix was 74.52 works better than ever

You should get the vertical IC checked starting with checking the supply voltage on it. This is a small flat IC attached to a heat sink with about 9-11 pins. This tv model should carry an LA7837 or an equivalent IC. If supply is present, check with means of a magnifying glass for dry solder joints on it. Resolder the pins on this IC if necessary and should work out fine. Model tends to suffer from this problem.

I suspect you have simply switched to an unused input. If you use the original remote you can probably switch the input readily back to what you want.

Hello there. I'm sorry to say that it sounds as if the element that actually energizes your screen is bad. It is most likely overheating. or quite poosible the power converter lost a resistor or 2.

There are bad solder connections on the vertical IC. This is a small flat IC attached to a heat sink. It should have about 9-11 pins and may be marked LA7837 or something similar. Resolder the pins on this IC and that should resolve the problem.
