20 Most Recent Mitsubishi TS-5545 55" Rear Projection Television Questions & Answers

if it is the model indicated here it is way too old to even attempt to repair.

Many parts for this set are not even available so most shops will not want to take it in for repair.

as old as the set is it is most likely broken or bad solder connections on the circuit boards inside the set....

mitsubishi projection TV turns off by itself after a couple minuts of viewing TV?

Mitsubishi... | Answered on Sep 28, 2010

A couple of things:
1) Either a bad power supply or a flyback 'supplies the high voltage to the 3 CRT's' .
2) The HOT 'High Output Transistor' is gone bad or the leads 'solder joints' have cracked and are not making a good connection.
time to get it into the shop or have a tech come to your residence to look at it.
Good possibility of getting it fixed.

It sounds like an electronic problem with either the power supply or somthing tripping the power supply up. If you don't have an electronics background Id suggest taking it in to a service shop for a quotation.

You need a professional.
Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

Are you able to view the TV's onscreen display menu?  If not, you have a problem with a video board and service is required.  If the menu does appear, you will have to check the cable/wire connection and make sure it is snug and in the correct location.

Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.

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.

Better pry it's not the CRT ( 251C080010) these are No Longer Avalible But with a set this old (1996) and being a Mitsubishi you probley have a bazzilion capacitors that have weakened up over it's 12 years In another post you say you got a convergance problem those Ic's STK391-020 are still avalible, but where you might start is to simply resolder the entire dflection and signal board. Mitshubishis are well know for running hot and burn the crt's making the pix terrible. Then after spending a few hundred on Ic's capacitor, resstors and such do ya know what you will have? Thats right a 12 year old set. This may be a fun one to play with but don't plan on making this the center piece of your entertament center

If the status LED shows a consistent green light it means that the power is on, on the TV. ... If the status LED is blinking yellow, that means the lamp cover is open. If the status LED is blinking red and then blinks yellow, that means you will need to follow that code to find the problem with the TV.Aug 14, 2013

The main power supply regulator section circuit fault. Either it will be a separate board, or the part of main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size
