Re: vertical red

If your talking about the lines for the convergence, I would say it needs a professional alighnment or a componet, such as the convergence IC's are going bad on your TV set. there are no user replaceable parts on these tV sets, so unless you have any solid state repair experience, Play it safe and call in a pro to assist you in this repair. Good Luck PS Pleae do not forget to rate this thread.

My tv has many lines in the screen. what kind of problem is this and what does it need to be fixed?

You may be suggesting a convergence problem..when the blue and red boxes will not center. You have bad grounds on the convergence ICs. Resolder or replace theses ICs. Or you may be asking about a problem in the vertical section. Vertical problems will appear as horizontal lines on the TV. In this case you have bad capacitors near ithe vertical IC and must also resolder or replace the vertical IC.

Convergence lines are SLANTED. Red line is above

Your TV most likely a convergence failure. ( common problem )

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 Their kits include a photo instruction guide, original OEM Sanyo STK chips, convergence resistors, pico fuses, thermal paste, email/phone support, etc.

Can't control red convergence on VS-45607

The STKs are three channel ICs they each control horizontal and vertical of one color the third channel controls part of green and the other half of green is controled by the other ICs third channel. Its customary for the Ics to fail and only have one channel bad in the IC. However its recomended to change both because of the bad Ic having green it can actually weaken the other IC and that one will fail shortly.

Call your local TV shops and ask if they have any 45 or 50" screens in the bone pile you could purchase. You should come up with something for a reasonable price $35 to $50 in good to excellent condition. You can cut down the screen to fit if you cant get the exact size. Good luck!

One of your convergence IC's has either cracked loose or burned out. The IC will have to be resoldered or replaced and then the convergence circuits realigned. If you do not have experience in repairing convergence circuits then have a qualified tech handle it for you. This is by far the most common failure in the projection sets and a good tech can have it fixed in about an hour and a half. I charge $150 for that but shops in your area will vary, so call around.

Mitsubishi VS-60705 - picture flutters vertically and horizontally

This sounds like one of the 9 volt regulators on the small signal board is going bad, supplying less than 8 volts. I have seen this is several of those sets. The IC needs to be replaced and if you do not have experience in servicing projection TV's then I suggest letting a qualified tech handle it for you.

This symptom seems to be a vertical Sweep fault cause what happens is theres a protection circuit in this set that activates when it sees theres no verticle sweep, it shuts off the picture on the set so that the tubes dont get lines burnt in the middle and become damaged. If you know your way around a TV set then you could locate the vertical output IC and resolder all its pins first as well as anything else in that circuit that looks like a cold solder connection. Then i9f it still does the same thing I would just replace the verticle output IC as well as the B+ supply capacitor off the flyback xformer for the sweep dirived power supply. Now if your not knowlegeable about these HI VOLTAGE circuits my advice would be do not attempt the repair yourself as you could get hurt and /or cause more problems with the set as there are no tubes in this set to test except the picture tubes. Contact Mits. at this #800-332-2119 or look in your owners manual for a contact #. Good Luck.
