Checking electrical components--Mitsu WS 55513

Hi... I got a PDF file service / schematic manual for the Mitsubishi WS-55513 and will try and follow your guide. Am I looking on the main power board or the secondary power board for these Pico Fuses and Limiting Resitors? The schematic is so **** small, and my eyes arent what they once were..
LOL

Thanks in advance...

What you are looking for are green resistors. there will be about 5 or 6 of them on both the right side pcb and the pcb in the middle. they should have no resistance. The one or ones that are open will point you to the circuit you need to check.

Blinking Light Problem on Ws-55513


If bad capacitors are the problem then replacing them will involve soldering.

If the problem is something else less visible then fault finding will be difficult without the proper service manual.

Try changing the settings on the Xbox under display to 1080i. If it is 1080 p, or 720p, the image will look funny so make sure it is at 1080i.

The infamous flashing green LED problem is usually due to a failing or faulty DM board. I purchased the PDF manual online and was able to locate and remove the components as necessary.

If you can solder, and are semi-proficient with electronics it is 4 bad capacitors on the DM board...

Otherwise there are facilities that can repair your failed board for about 275.00 or replacement of the board is between 350.00 and 500.00 buck USD.

Good Luck with your repairs....

Rechecked the conections and still


well..that's interesting...before you begin, have you determined a source for replacement components? I'd be hesitant to do all that work, NOT knowing if there are readily available form fit function components for it. Don't assume that overseas manufactured appliances have a ready distribution system for spare parts.

The DM board is the one with the digital connectors on the back panel. If you already have it appart, you may as well check the caps on all of the boards. The caps that go bad are typically Jamicon brand caps in 1000 uF and 330 uF values. There are also a couple of 3300 uF caps in the PS that cause problems.
