Small horizontal red, green lines from top to bottom of screen. Less noticable on HD. Help??


Hi,You are experimenting the most common failures on sony sets:"Light engine problem" basically your tv uses 3 LCD chips that are like tiny screens that create the image and colors.When you get lines like what you are describing its affected by those chips.I will suggest to contact Sony,sometimes they are willing to repair it or give you a certain deal ,since they were in a law suit for faulty light engines.Good luck and God bless you!

Tip

"double vision" caused by bad solder points on convergence chips (check before...


Before you order new convergence chips to try to fix the double vision or 3D look on your tv check the solder points for the chips. If you are able to smack the side of the tv or tap the heat sink for the chips and it corrects the problem than chances are the chips are fine butone or more of the solder points are bad. When I looked at the joints for the chips I noticed hairline cracks around the base of the joint. Re-soldering the joints for the convergence chips solved my problem.

Lots of Blue shadows off to side. concaved picture almost


HI, this is a failed convergence chip that is located on the convergence board. it will need to be replace ASAP. you can just replace the chip or , you can order a new board.

Replacing the chip can be a rough job if you don't have tech experience. if you are a fluid tech and you can solder and know your way around a circuit board, just replacing the chip will cost less. if you are not an experienced TV tech, i recommend a service call to the nearest TV tech to replace the convergence board.

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.

Sounds like your convergence chips are going. Unless you are real handy with soldering iron I would suggest having a tv repair shop service it(probably cost $200-300). If you are handy then I believe the chips you need are Sanyo STK392-110. There should be 2 of them. be careful if you order them online, there are lots of chinese knock-offs out there.

Update and a few questions (Convergence Problems - VS-55601 55 in Projection)


yes, they go bad interment because they have a large current go thru them and they generate heat, they are mounted on a heat sink with white silicone to help disapate heat. replace both not just one, try MCM Electronics get heat sink compound also
