Sony bravia flat tv model KDL46S2010 only power light comes on nothing else.

You have either a bad main or power board, start by checking your PSON voltage if you have a multi meter and comfortable doing it, if its normal then replace the power board if its missing but the standby voltage is correct its the main board. Below is a link to the service manual for your TV

I have a Panasonic Th-58PX60U Plasma TV with a sound issue. I was able to get sound out of internal spkrs briefly and the lost and none out of external jacks.

I didn't take the time to look in the manual on your set but believe the raw DC comes from the PS board to the main and its reduced on the main so I would go with the main board. Here is the service manual for it

Is there a repair manual for insignia NS-LT-DVD-26?

Service manuals are hard to find now a days, even service parts. Check the link provided to find the main board for your LCD.
Finding the tuner alone might be hard or if you do, it might cost you the same as replacing the entire main board.

test the main control board. God bless you
Main Control Module / CCU
The main control unit is the circuit board located behind the console. If the door switch tests good the main control is usually the problem. Check all connections for a goood tight fit. You will need to refer to the tech sheet or service manual to check this further. The main control is easy to replace.

How do I test the y-sustain main board from a philips plasma model is 42PF7220A/37 the Y-Main sustain number is LJ92-01200A....both buffers tested bad but now I dont know how to test the y-main...i...


As such boards are cheap and fail quite easily (both the two sustain and the buffers) Philips service manuals are more oriented at board swapping then at proper testing. In this particular case the buffer boards fail very easily because of a bad soldering to IC. The short will regularly blow the main sustain board.

To start when a main sustain (e.g. Ysus) is fried the TV will go in protect mode with the led flashing in standby. One test is done disconnecting the Sus board (with power off) and restarting the TV. If TV does not go in protect, then the sustain board was good.

If there is no protection:

The first thing to check on a main sustain board is the fuse. If the fuse has blown the IC is probably fried.I believe fuse is F5004. Check for swollen capacitors that may have blown. Test the FET. That is the core of the board as it is the power amplifier.

Here the service manual:PHILIPS_SM_15540.pdf - Right Click "Save Target As"

Here a more useful service manual. Check and follow troubleshooting diagrams in manual.

Here some troubleshooting from users.

Note:if buffer board was shorted, then the main sustain board is usually faulty.

I have no power to usb ports

you may check whether those ports are connected to the main board. There are some jumper style outlet on the main board for USB ports but may not be connected. Check the print on the main board or the manual you will see them.
