    The power control board is shorting because of a defect in the manufacturing of the component.Remove the aluminum plate from the right side of the board,it has 5 screws holding it to 3 rails.Take that off and replace the back panels.(Be sure you unplug the set first)Thats what I did,tv works fine now.

Most probably the Inverter Board is faulty or in worst case, LCD Panel itself is faulty because you already replaced Power Control Board and the Main Board.

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.

Fault at its main digital board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.

In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.
Before going further; try a hard reset first. If it does not help you, replace the main digital board. There are two methods to reset TVs. The first is simple to do; a Hard Reset. The other is somewhat skilled; is a Factory Reset (System Reset). To make it a hard reset, just unplug the TV from AC mains wall socket, and re-plug it back after 15 minutes or so. If you do this by overnight is better. This procedure will make it a hard reset. If you want to make it a system reset [Factory Reset]; you have to enter its service mode option, and select the factory reset option. If you wish to get some details; visit the site linked here.

Samsung plasma tv made a really loud pop and the screen and sound do not work but the red power light won't come off unless the tv is unplugged what happened?


The main power supply regulator board has the fault. Check if any electrolytic capcitor/s has bursted out. Replace them if any. If this do not help you. repalce the board as card basis.
Replacing it as card basis is fine, rather than making 'surgery' to it.

Need repairs on Technics SX-PX103-M Model.


Have you had any luck with your Technics piano? I've got the same piano and Mine does not work either. No lights on the control panel, only red power light comes on. Does yours have any led lights besides the power light that come on? I've investigated and I have learned a lot from this piano. 4 main boards. Im pretty sure I've got it down to one board. Interested in selling me any boards from your Piano??

Polaroid FLM373b No power.


When the filter capacitors went out , the power supply will feed AC instead of DC into the circuit board and may have damaged other circuits. Do you get the 5vdc standby voltage? it should be on one of the power supply out put connector the minute the you plug in the TV, you must have this before go further.

Hi,
Symptom shows that Mani Board is bad in your TLX-03210B Polaroid TV and need to be replaced. I do not see problem of capacitors in power supply board. Problem seems in system control section of TV that is located on main board.
Click Shop Jimmy as it is best source to obtain boards of LCD TVs.
Please call Shop Jimmy for main board availability as currently its out of stock.
