The system will not let me post to a link, I wrote: OK first off, as you stated, you will for sure need an original replacement remote for this TV set to make any types of alignments. You may also have a friend relative or maybe a neighbor who may have a remote you could borrow. If not, there is one available here http://www.remotes.com/remotes/servlet/rs?a=gmi&smodel=KP46WT510&brand_pn=SONY_KP46WT510&mode=large&uid=11859736726080 Now the convergence IC's, there are two of them that will need to be replaced, the number is STK392-560 You can get the original Sanyo IC's from HERE http://www.mcminone.com/search.asp?keyword=STK392-560&btnSubmit.x=10&btnSubmit.y=8 You will also need to get some heat sink compound and apply to the backs of the new IC's before you install them. Now after all is said and done, before you plug in the set, take a multimeter and check resistors R 8122,and resistor R8127. These two resistors supply the voltage to the IC's. They are 7.5 ohm resistors. The R8122 carries the negative 22 volts and the R8127 brings the positive voltage to the IC's. Next, check the circuit protectors around the IC's also. They are PS8001,8002,8003,8004,8005 and PS8006 and make sure these are not open. These circuit protectors are nothing more then 3.2 amp fuses. I do not have the KP46WT510 service manual, so you will have to go to servicemanuals.net Good Luck

I replaced the Convergence IC Chip STK392-110 for my PT-53WX42 Panasonic HD Rear Projection TV but I found burnt resistor(resistor #)R7053,R7002 & R7005.Can someone tell me the part# ,description,resistor value and power rating.I don't have the schematic to look .Thanks

1. Try this - hold the menu button down for 10 seconds. TV should power up; you
will have to turn off front panel buttons on menu.
2. You can also try plugging in the TV through the USB on its panel to a computer or USB charger, and it may work. However, this is only a temporary solution.
3. Powering down the set or putting it in standby may have allowed the power supply to cool. Weak capacitors often go out of spec when they cool, thus preventing a section of the power supply from firing up properly again. There is a simple trick...just warm the back of the TV with a hair dryer for 5-7 mins after you have unplugged the TV. Look for the little areas of holes in the back panel of TV. Use these as your guide at where to use the hairdryer, but don't hold the dryer too close (say 5-6inches away). (Make sure the dryer is on High heat). If the TV doesn't turn on after you have heated it up (like it tries to come on but then turns off) you need to unplug the TV again, this resets it. And repeat those steps till it works. Resetting the TV after it fails to turn on is the key. Also, just leave the TV on. Don't turn in off. Since it is LCD, it doesn't take much power...only a few bucks extra a month for your utility bill.
4. A circuit board may crack about some of the larger components mounted on it. You can inspect the PCB's for fractures, and then repair them. It may also be poor soldering that has failed. I would be checking for these things first.
5. If you want to go in for a long term solution, you can easily replace the whole power board or just change the faulty capacitors. You will have to open the back panel and take a look. You can make out which are faulty, because their caps will be swollen on top. Here's a sample pic (not same model):
Check the specifications of the faulty capacitors, and get the replacements from your local electronics shop. If you are comfortable with this, you can use a pair of needle nose pliers to G-E-N-T-L-Y pull out the defunct capacitors. Once that is done, solder in the new capacitors carefully. If are unsure how to do this, try to get a friend who knows how to do this kinda stuff do it for you, or get a qualified technician. Warning: If you do not have a background in electronics repair, or are inexperienced, get a qualified technician to do it for you.
REMEMBER there are very dangerous voltages inside a TV that can KILL. Be sure to work SAFE when dealing with electricity. DISCONNECT THE POWER BEFORE YOU DO ANYTHING.
Hope that helps!
If your issue is not resolved, please do not assign a rating just yet. Please post back as to what steps you took, results, etc, and I will try to assist you further as best I can. I am here at your service.
P.S. -You can rate this solution with one of four votes, if you feel your issue is resolved (remember that at times a bit of to and fro dialogue may be necessary to resolve an issue).

You can get the entire convergence repair kit which contains all the parts listed at the following link its called the AV48WP30 Convergence repair kit , but it applies to your model as well, and they include free installation instructions.

Parts for $80 to 90?!?!? HOGGWASH!! It's $21 at mcmelectronics.com for an orignial Sanyo. For a WS-65711 it is indeed a STK393-110 and you only need one of them. I've heard that this usually the culprit when there are convergence problems. The pico fuses can go, but that's pretty rare. If you can solder and feel comfortable inside your TV, then this can be done at home so you'll even save on the labor. I suggest buying the part yourself and asking them to install it.
