Jetway v266b rev 3.0-what ram memory to use??


You might wanna try DDR RAM, the highest size you will be able to get is is 1GB per module, so buy a few if a DDR module fits, and you may also want to look at the capacitors, make sure they're not bulging, I've seen a lot of these boards in computers, and when I've had to repair them, 99% of the time it was bad caps, so if they are bulging, I reccommend nichicon K series caps (NOT KZG, they're known defective)

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.

This will show the correct disassembly and test procedures.

Good luck.

Tip

Mitsubishi LED keeps flashing green constantly


This problem happens on many Mitsubishi TVs, older CRT projections, and some of the older DLP projection TVs. The flashing LED means the TV is booting up, but it should stop in 90 seconds after plugging in AC power or resetting.

The typical cause for this is bad Capacitors (caps) in the DM module. 95% of the time its the caps, but could need a new DM module. Almost always the caps are bulged like in this picture:

a2fdbba.jpg

They should always be flat on the top, if they're bulged, they're bad. In some cases they will not be bulged but will still be bad.

In almost every case, these caps are 1000uf @ 16 Volt caps, and should be replaced with 680uf @ 16 V caps @ 105c. The caps are always solder in parts.

In the CRT projections, there are 4 or 7 of them on the DM module that sits on the very left side of the chassis when viewed from the back of the TV set.

In the DLP projections, there are quite a few more, and they are on the FMT and DM board (4 each) and sometimes 4 will go bad on the power supply. The DLPs also have some larger caps that will go bad on the power supply causing a false lamp error.

In the case of the DLP caps going bad, Mitsubishi rebuilds the "Chassis" for service centers for about $250-300 + labor required. This is typically the recommended repair for these sets as they require extensive disassembly and mechanical skill to repair.

In the case of the CRT projections, repair is quite easier and can be repaired by people with some mechanical know-how and basic soldering skills.

For either repair, search the web and you can usually find a tutorial with instructions and explanations like the one found here:

Sounds like bad capacitors in the power supply. check for bulging caps or replace the power supply

When I turn on the TV it has a loud squeal for about 10 minutes until it seems to warm up.


I suspect you may have 2 capacitors in your control module that need to be replaced. When these caps start to go bad it will often show up as a problem with the sound. However, when they get really bad they can prevent the TV from turning on. Please see the link below, posted by stiv0. It gives detailed instructions on how to replace these caps and to tell if they're getting bad. If you follow these instructions you can take the back off the TV and check out the caps. If the tops of the caps are bulging they need to be replaced. Just be sure to replace them with the correct value (1000uf) and use caps that are rated at a higher voltage than the originals. I replace the 10v caps in my FLM 373B with 30V caps just to be on the safe side. If you know how to solder this is an easy and inexpensive fix. If you don't know how to solder find a friend who does. These caps have positive and negative terminals. It's important you solder the new caps in with the correct polarity. Stiv0 gives instructions on this. Even if the caps aren't bulging this fix is so inexpensive, less than 10$, that you may want to try it anyway. I hope this helps you out.

Picture goes to verticle colored lines then goes blue screen tv s


This is likely capacitors failing in your DM or FMT module. This model is know for the 1000uf caps going bad after 4 years or so. There are 4 on each board, plus 4 on the power supply that may go bad. You can tell by the bulging tops that are not flat. Two 3300uf caps go bad in the power supply regularly as well. I recommend getting a service center to send the whole signal block or chassis into Mitsubishi for rebuild to get it all taken care of. The dissassembly is very difficult and frustrating. If you have tons of time and determination you could repair yourself.

Flashing power light tv wont come on mitsubishi 1080


If the tv has the continuous flashing led, you have a DM board problem. It is likely bad capacitors in the DM module.. there are 4 of them 1000uf caps that will go bad. They will get a bulging top on them when they go bad. . Mits recommends replacing them with 680uf caps with a comprable or higher voltage rating. The DM module in on the left side of the set (viewed from the back) and is somewhat difficult to remove.
