If you have tried to adjust the convergence on your TV within the menu feature then typically you do have a convergence problem. Check out this video to be sure...

You need to purchase the convergence repair kit.Are you handy?
It comes with instructions.
A TV repairman will charge about $300-$400.
The kit is a fraction of the cost

You will need a repair kit for the convergence ICs, resistors, etc.

Here is the best kit I've ever used.

It comes with:
Kit Includes
  • OEM Sanyo Convergence Chips. Each kit includes the correct replacement convergence chips verified against the service manuals. Two chips per kit unless your model uses three - in that case we ship three. These are genuine OEM Sanyo chips. Sanyo was the primary supplier of convergence chips used in TV sets made by Philips, Sony, Hitachi, Panasonic, Toshiba, Mitsubishi, and many others). We do not use lower quality generic convergence chips in our kits like other sites.
  • Convergence Resistors - These are specifically designed and rated for convergence circuits. Do not use anything but convergence rated resistors when doing these repairs.
  • Thermal Paste
  • Photo Instruction Manual - Complete Instructions on how to repair your TV. This is a step by step photo instruction guide that will walk you through each step of the repair. All of our repair guides are non technical and easy to follow. You do not need to have any prior electronic repair experience to use this kit.(Download Version - allows you to view/zoom/print from your computer)
  • Soldering Instruction Manual - Complete instructions on how learn to solder like a pro in less that 30 minutes.

Thank you and best of luck!!!!

Heatsink? Nonsense. Almost any heatsink is no more than a hunk of metal.

There is a likely shorted transistor on the main power board (possibly the Horizontal Output Transistor, HOT). They are very inexpensive to buy (about $5) but tricky (and dangerous) to replace if you are not familiar with electronics.

There are A LOT of wires, cables and connector in this TV that need to be undone to get the main power board out.

I love this TV and was able to fix mine in an evening... but I've 20years experience in electronics.

Unplug the TV for safety - even unplugged, there is enough energy stored in the electronics to be very dangerous.
The bottom speaker grill snaps straight off. There are a row of screws under the screen around the screen bezel that must be removed. The bottom of the screen will become loose and the whole screen assembly slides up, like opening a window (there is a bracket under the bezel at the top of the screen that the bezel slides off of.) My screen took a lot of effort to disengage the top bracket - careful not to break anything!!!

Once the screen is off, put it safely aside. There is a mirror in the back that can be cleaned with a damp cloth (not dripping wet!). Remove a little dust at a time and keep washing the cloth out between cleanings. Be very gentle. If you push on the mirror it could break If its never been cleaned there is sure to be a lot of crud.

Below the mirror are three colored lenses. CAREFULLY use a clean lightly damp cloth to wipe each one. Don't mess with any of the adjustment screws and levers on the lenses.

Before putting the screen back on the TV, carefully clean it with a damp cloth too. Slide the screen back over the top bracket, put the screws back in, and pop the speaker grill back on.

Its a good idea to readjust you convergence too.

When I cleaned my set, I was amazed at how bright and sharp the picture was!


Be Careful!

I had a similar problem with my 42 in Philips LCD HDTV.


Here was the problem. My Power Supply Board had several bad capacitors. I opened my TV (warranty was expired of course) and found four bulged capacitors on the PSB. Many major electronics companies Philips/Magnavox, Sony, Panasonic, and others were sold capacitors that failed in 2-5 years instead of 10-20. The capacitors fail prematurely due to a lack of preservatives. Unfortunately, they were installed in all sorts of devices and cause a wide range of failure problems.


Here are some options for you.


1. Have it fixed by a professional $$$$$$$??????? (Is it under warranty?)

Remember, TVs CONTAIN HIGH VOLTAGE AND CAN KILL YOU! Do this at your own risk.

2. Open your TV and find PSB. (The board that the power cord plugs into) Check for faulty caps. If you find some (bulged or leaking) bad caps replace the entire board. The entire board costs around $250 right now because they are in high demand right now. They can be found online. I would definitely shop around though.


3. Remove and then replace individual faulty caps. This takes some soldering skill.

Caps are inexpensive and if you can take care of it yourself it will save you hundreds.


This may be your problem. If you determine that it might be.

I have a Tip/How TO tutorial on this site that may also help. It gives step by step instructions for replacing caps on PSB #715t2432-2. If this is your board you are in luck. Here is the Link: Fixing the Philips Turns/shuts off on its own problem. I'm working on uploading pictures to help guide people though the process as well. Let me know if I can do anything to help.


Hope this helps and if it does please rate it accordingly. Good luck.
