Mitsubishi TS-4545 Shutsdown at start up

Hi,

To have an idea how to repair the convergence problem on your set (WS-65809), watch the video below.


tvrepairworld.com has a convergence repair kit for this model number. It contains the chips and the pico fuses that are know to be faulty, instructions that will guide you in the whole process of repair.

Hope I helped you.
Good luck and have a great day!

Hi mopacdave,
If the symptom didn't cure by convergence adjustment through the remote control, this is an indication of faulty convergence board inside. You may replace the convergence IC's STK series and some of the resistors around because its already gone bad.If these parts replaced with new one, your unit will back to normal again. Also, consider bad solder joints in that area, it will do the same symptom like what you've encountered right now. Find it first and re-solder. If you don't have necessary tools and test instrument and can't do the job yourself, I would advise you to look for a qualified technician to isolate the problem.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

Projection TV sets are known to have two common problems. The first problem that is common to these sets is convergence failure. When this happens the TV will usually look 3D, Wavy/Distorted, etc. It may also shutdown and blink an error code.

The second common problem with Projection TV sets is dull video, halos around objects, white looking video, or red overpowers the screen. This is commonly caused by the fluid in the lens being clouded overs. To get fixed either call in a local TV repair company or goto sites such as Tv Repair Kits to get a repair kit with instructions. Here is there link.

They have put together complete kits for most models that include the parts, step by step photo instructions, repair assistance, etc.

The light bulb inside has probably burned out. Should be an easy repair.

That is a VZ3 chassis, similar to Mitsubishi models Ts-4545, Ts-5045, Ts-5545, Vs-4543, Vs-4544, Vs-5043, Vs-5044, Vs-5047, Vs-6043, Vs-6047 and has common failures in the vertical circuit, specifically vert Ic401 which is a La7845 which is usually caused by defective C402 100uf 50v and/or open 1.2 ohm 2 watt R510 next to FBT.
If not that check C268 off Q215 on signal board 22mf/50v and Ic200 on signal module Cxa2025s. However the vertical failure is more likely.

On the service manual you find a convergence setup procedure, did you do that?

This is the VZ3 chassis. Solder joints are famous at the yoke plugs, flyback and horizontal drive transformer.The blue convergence is the Convergence ICs need replacing. I will try to locate a manual for you.

easy way to adjust the convergence is, first off blue back option. Then check snow on the picture., if each snow carries any color on side. adjust convergence till color disappears. take long time but it is very easy no need other equipments

No if the problem is the screen, you will need to replace the entire screen assembly. some screens come in two parts. The inside of the screen is called the freznal lens, the outside of the screen is called the lenticular lens. Good Luck

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.
