How do I hook up a dvd player to vs 4544?


Its a old set but hookup should from a DVD player be to the rear audio and video inputs---note color of jacks on player--you will need for that old set composite--yellow(video and color), red and white for sound.

If the player does not have them (composite) you have a real problem.

Once connected use the input button on the front of the set to change to that input that you hooked the player up to (video 1 or 2 etc.)

Mitusbushi VS-4544 Horizontal lines then looses picture.


I'll take a guess here that the lines are at a slight angle. I believe that these are "retrace" lines and are an indication that the flyback transformer is starting to fail. The vertical IC would cause a collapse of the picture and bad caps in the circuit would effect the linearity of the picture. You can check for poor solder joints as they could cause any nunber of symptoms.

Keep us posted.

How to fix the video power supply for mit VS-4544 ?


Let me preface what I'm about to suggest with my own comments. I've been a TV Technician for more than 20 years. That said, you don't fix it without calling repairman or you wouldn't have posted here. In this unit there are common lytic caps that should be replaced without question. By location number and value they are: C979 2.2uf/200v C531 2.2uf/160v C551 2.2uf/160v C981 22uf/50v C402 47uf/35v Next it might be a good idea to ESR test other caps in the B+ line. ESR stands for (equivalent series resistance) It's a way of measuring the cap's effectiveness in a circuit. There are testers on the market for just under $200.00 for the backyard technician and they are a must. Check the set for ring cracked solder joints. The symptom of leaving it off for awhile and then being able to get a picture suggests that it could be ring cracked in one or more areas, usually areas of high heat. When all else fails there is calling the repairman. If you don't know how to find a reputable shop in your area I might suggest contacting NESDA (National Electronic Service Dealers Assn.) who can give you some reputable shop contacts in your area. Good Luck! Bill

Tv wont come on


Sounds like the Horizontal Output Transistor shorted. TVs are dangerous to work on if you are not trained. The transistor can be checked easily with a dmm. If it is bad the flyback should probably be replaced too. If it is ok, you have a short somewhere else and need to isolate systems until the fuses quit blowing or hook it up to a variac and do checking to see where the short is. My bet is on the HOT. Again, if you are not qualified have a professional look at it. Good luck.
