You can do it yourself. You will have to go into the light engine to get to the filters and they are glued in at the bottom with one very small screw holding in the top of each filter. But you only have to replace the blue one. Very important not to get any finger prints on the filter. If so it cannot be cleaned and must be replaced again. Just be careful with the LCD cube that is surrounded by the color filters, it is very fragile and hard to get a replacement for that. But yes you can do it.

Crack in drum at seam


We had the exact same problem with our LG dryer but the crack was in the front near the door. The service tech as well as the engineer from the LG R&D department both agree that it is a manufacturing defect...the result of a poor welding job by LG. The service tech replaced the dryer tub today and the dryer is as quiet as when we first bought it. I paid for the part and the repair myself to get it fixed quickly. The service tech said to use it with the crack could be a fire hazard since the heating element is open under the tub. However, the service company we use will reimburse me for the cost of the part if LG agrees to reimburse them. I am in the process of working with the resolution department to get them to agree to pay for this part. It is no longer under warranty but since there engineer has agreed that it is a manufacturer defect, I am hopeful I will get my money back!

Rust stains


Did this just start. I repair these all day long and have for years and I have yet to see this be the scenario. If you are on city water and this just started happening, you have a bad tub bearing. If I'm correct, what you are seeing on your clothes is grease from the bearing. I agree that it looks like rust but I don't think it is. If they are correct, it's funny how it just started happening. Iron would have be in your water all the time, not just lately while washing clothes. Before you spend all that money putting a high dollar filter system on your water. Please have a service technician check this out for you. You might want to coincide buying a new washer, this way you don't have to pay the tech, the filter installer or the filter system.
Please rate if this solution is helpful.

Is it a fair fee?


I own a tv repair shop in jacksonville, fl and I know that with that model we always send the chassis to mitsubishi for an overhall this would cost around $900 but we send it to mitsubishi, we dont do it ourselves because there are many parts that should be replaced that only mitsubishi can get, they dont sell them to anyone. BUT your problem just needs the 2 caps in the power supply replaced for now. in the future you might need the rest of the work done but my thoughts are if its not broke dont fix it! So i would take the chassis out and replace the 2 caps in the power board and be done with it untill it brake again. If you cannot get the chassis out send me an email and i will give you some help.

This can be caused by a problem within the "D" board or a bad CRT. If the D board can be fixed, that would be the least expensive repair. Even so, this will require a service tech. Depending on the cost of an estimate, you could call a service tech and explain that the TV may need a "D board" and try to get it serviced. If the D board replacement does not fix the problem, the CRT would be next. Maybe the service tech would allow you to pay a small fee for the experiment and a fixed service cost if it is the D board.
