I have a sylvania 32in replacement tv circuit board model srt2232s It doesn't turn on anymore , fuse is good , buzzing coming from a transistor I think any thoughts . Thanks


Hi there, sorry to hear. That "buzzing" you hear is most likely that power supply onboard, pulsing in a failure mode such as a current limit situation. Check for shorted rectifiers, and the common bad capacitors.

Try another input and another source such as a DVD player. If you still get the buzzing sound, you could have a faulty power supply output or a fault in the audio circuit of the main board.

When i turn the tv on it attempts to go on but then you can hear the on/off switch a second time and it doesn't turn on


Good day!!!!


That problem is usually cause of faulty capacitors on the power supply board..

Just follow this instruction to fix your TV..

1. Open the back cover of your TV.
2. Look at the power supply board..Its normally connected to the power cord..
3. After that,,try to look at the actual image of capacitors if it is bulged on the top so that you can easily determine the bad capacitors..
4. After that,,try to replaced the bad capacitors using soldering iron and soldering lead..replaced the capacitors only with the same type ratings and value..
5. Some of the capacitors not bulged so its better if have a capacitance meter

Plasma Television won't turn on


Hello,

Hi
A common problem for these is bad capacitors in the power supply, Remove the back from your Tv and look at the power supply on the left hand side.

You will see roughly around 9 x capacitors that are bulged / domed shaped on top usually these are valued at 3300uf 10V any that have bulged or leaked a brown like substance should be changed.
This will cure the problem as they overheat being sat next to a heatsink that gets very hot!
Try and change them for the same 3300uf but a higher voltage.

if otherwise the power supply board is faulty you can try websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.

Hope this helps

Hi,
Your TV requires ballast power supply board that gives you buzzing noise when TV turns ON.
Ballast supply board is available in Part Store and replacement of that board requires expertise.
