Question about Mitsubishi WS48511 48" Rear Projection Television

1 Answer

Bouncing Picture on WS48511 MITSUBISHI PROJECTION TV

We have had this TV for several years and have no problems except recently. It first started when we would turn the tv on and the picture would bounce a lot, until about 30 or 40 minutes and then it would be fine. Someone told us to leave the tv on because that was a problem with the projection tv's. So we have been leaving the tv on but turning off the satellite when we turn the satellite back on it's starts the bouncing again and it can take up to two or three hours for it to stop. Sometimes we don't turn neither one off and the bouncing starts. Does anyone know what this might be and how much it costs to repair? thanks.

I have seen this symptom a lot recently. There is a 9 volt regulator on the small signal board, and the output voltage on this IC has dropped down to about 8 volts, which causes that symptom. Replacing that regulator should cure your problem, and when I make a housecall for a set like that I charge $150, although I hear that the average service center charges a lot more than that. I also believe that it is never a good idea to leave a projection TV on all the time, so whoever told you that has no idea what they are talking about.

Mitsubishi ws48511 ghosting problem

You need to have the convergence output IC's replaced. These are large amplifiers which control where the red, green and blue beams land on the picture. When they fail you will get colored ghosts. This is a very common problem for any projection television. Any reputable tv repair shop can do the repair in your home and the average cost of the repair is between $225 and $325.

Mitsubishi WD-52525

Normal 0 The Mitsubishi WD-52525 has a serious capacitor problem as discussed in this forum overseen by a Mitsubishi certified repair technician: http://www.hometheatershack.com/forums/mitsubishi/11703-problem-mitsubishi-wd-52525-scrambled-picture-no-picture-2.html. There has been a worldwide problem in computers and TVs over thepast several years with faulty electrolytic capacitors (from Taiwan) thatdecay, dry out, swell and die. The power supply is often the firstcomponent to go bad, but other systems also degrade over time. As theforum explains , this problem is widespread in these sets causing multipletypes of display problems after several years of use. On my set, I also got a blue screen with a lighter blue ball in the middle. Mitsubishi is awareof the problem and will cover most of the cost of repairing the chassis, evenyears out of warranty, but apparently ONLY if you get an estimate from aMitsubishi certified repair station and contact their customer support BEFOREdoing any work on the set. I just followed the recommended procedure onthat forum and Mitsubishi is covering half the cost of my $700+ repair when my3+ year-old set recently died and showed only this blue screen on all inputs.

Color convergence problem

If you follow the instructions on the other thread, you should be able to resolve the problem. Try the simple stuff first. Resolder the pins of the convergence ICs and see if that alone resolves the problem. Sometimes that is all it takes.

Keep us posted.

Sounds like you need to clean the lenses and reflective area inside your set. It is easy and all you need is a screwdriver, windex and a paper towel. UNPLUG YOUR TV.   Take off your screen and screen protector and safely set them aside. 
Clean only the lenses ( glass part) and the reflective mirror type area on the top of the inside of your set.  It will look like new. You need to do this at least once a year.

Mitsubishi Rear Projection 65" tv picture becomes blurred bouncing right to left and color is red & green. TV is 8 years old approx. Any suggestions. Have not had any problems prevoiusly. First it woudl...

Sounds like possible solder connections on the convergence ICs. If so, you will see the red, green, and blue not lining up on ever input and even the mits menu. If you can bump it to correct, its just a solder connection, but if its out all the time then the ICs need replaced. This is a difficult repair only recommended for skilled technicians (40 solder connections + possible re-alignment needed)

Over scanning

These are good sets, but now the only way to get info is to search the threads here for your problem, and you may find it or you can pay the 9.95 and your problem will be solved and you can rated as that! Still its much cheaper than calling a repairman!
