SOURCE: 8 solder ic number for tcl falt tv

Can you please check for any jammed buttons on the remote and/or control panel? Try switching on the TV manually, while removing the batteries from the remote. If you notice same problem, the area to be looked into is around the system control area: like dry solder, leaky/dry capacitors and this should be done only by a qualified service technician.

SOURCE: 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.

To some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement. To some models sets, the back-light inverter and SMPS section circuit will be integrated at its main board itself. If so; the main board should be replaced. To some models of sets, all these section circuit will be integrated at its main board. If this is the case, you have to replace the main board.
