Not sure of which side, or why you want board #'s-------
 Power / Deflection board = 264102
 Power / Delection with PSB 910 on edge = 265324
 Small signal board = 264120R

Sound went out on tv was told i need a sound module,also need to get price of one

This model had a lot of odd problems including loss of audio.

With back off as you look from back are three large circuit boards.

One on the far left has another board about 4X5 inches plugged into it at the left rear corner.

Every one of these sets, that is the bad board--controls audio, remote and many other things. Large board it is plugged into is called Small signal Board (SSB), small one is small signal module (SSM).

It is plug in board held with two metal tabs at either end on bottom, It will have printed on it a part number (usually on a white label) with the part number, popular one ends in 2581 but are variations.

Last time I used one it was about 100 exchange(they are all rebuilt boards now)

Ten minute task to replace with back off and 95% chance it is your problem.

Everyone of these sets with no sound or intermittent sound, it was the problem.

Cant change channel and/or input mode, picture is horizontally scrambled?? Philips 55PP970104

Possibly, your small signal board needs replaced! It is usually located on the left side on the backside of the tv. It is inserted into the convergence board. This is a good place to start. Hope this gives you an idea to speak with a TV tech!

On my WS-55511 TV, after a power interruption, will not power up. All i get is a continuos blinking green light.I tried unpluging the tv several times, no luck.

Good Day,

LED does not stop blinking after plug in. Check for 12 volts at connect or PF pin 10 and 28 volts at connector PF pin 11, (on the board on the right hand side, but on the left side of board towards the back of TV). If the supplies are correct suspect a problem in the DM Assembly (part # 955C230002). Part is not available for replacement.

Check C9B01, C9B02, C9B03, C9B13, C9B14, C9B17 and C9B18 (1000 UFD, 16V, 105C) on the DM Power PCB located within the DM Assembly. If they are bad or not, replace them all with part # 181P734030 (680 UFD, 16V, 105C).

The DM (Digital Module) Assembly is located on the extreme left of the chassis from the back. It is standing in a vertical position. Remove cover and you see the Cap’s in one corner of the inside PCB.

Good Luck, Big IRISH.

Best to hard wire it because the board is not availabe. I have fixed a ton of those for that.
That is your Deflection board.

KP-46WT510 Sony, locating boards?

I have the same model tv, with the same problem... convergence ICs were shot.  As you look into the back of the tv, the ICs are located on the backside of the large heat sinks on the tan board.  The pico fuses are directly under the heat sinks.  
Removing the board is fairly easy with the exception of removing the red cables at the rear left side of the board.  You have to exert a lot of force to pull them out (they go into the grey tower looking thing) but they do come out.  
I recommend taking pictures of the board before removing, and then make sure you label each connector you pull off the board.  There are six screws to remove as well.
Check with Sonny and Barry at this site.  They gave excellent directions and have a convergence repair kit for your model tv.

Good luck!

Picture problems

The convergence amps have most likely failed. This is the number one leading cause for the symptom your describing and the most common failure on that unit.
Your Tv take two STK392-120 Sanyo Ics for convergence amps, located at Ic7404 and Ic7405 on the board and mounted to a rather large aluminum heat sink. In addition you will most likely have to replace R3159 and R3160 (6.8 ohm 1w) resistors and test the remaining low ohm resistors for change in value.
A shop would really be earning their money on this particular unit if they charged $400 - $500 for the repair. It is an extremely difficult set to work on and there are a number of little problems that can reach-out and bite when attempting the repair.
Good luck!
