SOURCE: Sony KP -46WT510 Convergence Problem


Yes - If you are failry handy and take your time its a DIY project.
Here are some of the most common symptoms and example photos of a convergence problem


  • Screen looks 3D
  • Colors don't line up
  • One or more colors can't be adjusted when using the convergence menu.
  • Screen is bowed or warped.
Here are some photos of convergence problems.

Here is a quick test....

Using your original remote go-to the tv settings then goto the convergence section.

Try to adjust the red and then the blue convergence.

You should be able to move them up, down, left, and right.

If you can't move them in all directions your convergence chips are bad and should be replaced. This is a common problem.

You will need to replace the convergence chips and possibly some convergence resistors and pico fuses. Its a fairly easy DIY job or you can call in a pro. If you want to do the repair yourself check the site www.TvRepairKits.com. Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

SOURCE: Have a Hitachi 53sdx89BA Rear Projection TV. Turn

Discharged Flyback Transformer. Removed main pc board from bottom of TV and flipped over, no apparent damaged components or blown board traces were found. Noticed a lot of flux in various areas on the board that seemed unusual (maybe TV was worked on before as I bought a showroom demo at Circuit City). Used a plastic screwdriver to remove all flux between connections on ICs, Transformers, Flyback Transformer, and various other components. Cleaned all debris, dust and crud accumulation (TV is over 10 years old and there was alot around the Flyback Transformer) from both sides of board using a lightweight paint brush.
Used a magnifying glass to check all solder joints for possible cold solders and found none. Did the same for Power Supply Board. Checked various ICs and Power Transistors for opens or shorts (in machine) and they seemed fine. Reinstalled boards, said a few Hail Mary's and fired it up.

The protector Led no longer flashed under power and lo and behold I got picture and sound!

I cleaned the lens on the projectors (again 10 years of dust accumulation) did a magic focus adjustment and it works fine!

After reading other fixes, I fully expected it to die after 10 minutes so I left it on all day and against all odds it still works.

What was the fix......Dirt buildup on and around Flyback and other components,,,,,,Flux conducting electricity between contacts on Flyback and other components.....or oxidation on connectors between Power Supply and Main Board.....I don't know.... all I know is that for the moment I saved around $ 300 - 400 in repair bills by doing it myself.

I need advice on LED TV repair I have a LG 50ln5600 TV that has quit working and I would like to know if it is worth fixing.


LG has been having problems with the panels LEDs going bad. To get to them the panel must be disassembled by removing the screen and defusers, usually 3 of them. Make sure you reassemble exactly as you disassembled. After removing the screen and defusers, you can now power the set on and see which LEDs are not lighting. Gotta have a quick eye. You can usually locate a replacment LED strip on E-bay. This is not an easy repair. I charge $200.00 to do them. Hope this helps. :)

Samsung monitor 2232bw plus backlight fade in black backgrounds scenes


Most common failures in these LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply C242 470uF 10V, C241 & C242 1000uF 16V, C261 & C319 680uF 35V failed as indicated in the attached picture, replace them at once.

If the power supply board is working then it is back light problem, first do a flash light test. If you can see the image in the flash light test, follow the steps how to test back light voltages: https://how-to-repair.org/repair/lg-tv-repair-manual-pdf/lg-led-tv-no-backlights-32ln5300-32ln5310-32ln5700-voltage-test-troub/2pyuXwNkBMA.html and follow the steps how to repair back light LEDs: https://www.youtube.com/watch?v=_poWTEihIJU Fix Led Backlights for TV or Monitor Lg Led Tv No Backlights 32ln5300 32ln5310 32ln5700 Voltage Test Troub Lg...

My LG 50pk590 plasma tv turns its self off as soon as I turn it on. I've tried turning it off and back on by the mains but still nothing. Please help


Same thing happened to mine and some guys came to look at it, turns out the main board had to be replaced, they say it went because the dust was blocking the cooling fans. I think mine is more modern as when ot went off the power light flashed 8 times, which was a code for what was wrong. See if yours flashes anywhere and look it up.

LG 50PK750 turns off as soon as I turn on


This issue is a common, but hardly talked about from LG. Your tv is probably 1 or 2 months out of warranty, and now you're hearing a series of clicks. ... If you have the courage to open the back cover of your tv, and you do "NOT" see any bad (bulging ) capacitors on the power supply, then it could be the voltage regulator. After weeks of fighting with LG to replace my tv, i decided to fix it myself. i'm proud to announce that my 50PK540 is now working. want proof? Take a look at the video i posted on youtube, then you will have a better understand why your tv is clicking... I'm also selling the repair kit for this power supply board on ebay now. LG power supply Board model number EAY60968801. With anyone of these PCB # EAX61392501/7, EAX61392501/10, EAX61392501/11, or EAX61392501/12 with the parts if this kit, I've also fis several 50PK750 models, Some clients have send me their broken power supply board, so I can do the repairs. Please Make sure that you've already gone through the process of troubleshooting and testing your tv's power supply board before making any purchases.. I recommend that you get a tv tech to check it out, because every tv is different. Email at bigthings09@gmail.com if you have any questions.and watch the video: part 1 & 2

My Sharp Aquos TV will not turn on...just a green ligth flashing...something to do with power...how can i fix it?


The most common issue on these is the power supply boards. Bad capacitors on these boards are the issue and there are repair kits available if yur qualified for the repair other wise you can get new boards and swap them out. This is the most common issue in the business right now. Sharp sets are a little different in ther design on the power supplies but parts can be had and repairs can be made. You will need to balance the price for the repair vs a new set. Just Google TV power supply repair kits for Sharp Aquos and you will find repair kits and information on the power supplies.
If this was helpful a vote on the thumbs up would be greatly appreciated for the free advice.
