Question about Mitsubishi WS-55859 55" Rear Projection Television

Open Question

Digital Tuner Power Up

I have had this TV since 2001. When you turn on the digital tuner the picture comes on for a fraction of a second, a "thump" is heard, and the TV reboots (flashing green light). After several attempts I have been able to get the TV to turn on. This does not happen on the analog antenna. Any ideas? I am no TV expert, but have a great deal of electronics and soldering background.

on the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.

SOURCE: Mitsubishi TV WD-62527 will not turn on

Hi there, this is most commonly known as power board failure in the industry. the capacitors are blown. if you are experienced in inspecting circuit boards this will be helpful. you will have to disassemble and pull the power board and preform a break point test. the bown capacitors are easily picked out. they will be swollen and discolored. If you are not comfortable with disassembling this set, i suggest a service call. just tell the tech you are experiencing a power board failure.

SOURCE: The TV was working great

When the power light comes on and then goes out, on the front of the set press both the MENU and INPUT buttons at the same time and hold them both in for at least 5 seconds and then release both buttons.

The power light will blink a 2 digit error code and repeat it at least 5 times.

The most common error will be 2 blinks, 2 blinks- a pause and then it will repeat it for a total of at least 5 times.

To get it to repeat this--you have to unplug the set, try to turn it on again and repeat the process.

The error codes are to try to narrow down where the problem is.

Let me know what error code you find and I will tell you what it means.

If this told you something you did not know rate this solution as very helpful as I do this here for free.

Post comment here if I can assist you further.

Idk if my tv is digtal ready it says its hd

The TV will provide an HD picture with a set top box connected to the HD input (AV4 or AV5). It does not have a digital tuner (only a NTSC analog tuner).

The manual is available here: . See appendix B on page 58 for the specifications.

I hope this helps.

I would like to know if the Hitachi 51UWX20B television can be connected to the internet.

Your Hitachi 51UWX20B is an HDTV-Ready TV. No Digital Tuner. HDTV-Ready means that your TV set is capable of displaying analog and high-definition digital pictures, but without a digital tuner, it cannot receive the digital signal. An HDTV-Ready requires an external high-definition TV receiver (digital tuner) in order to receive HDTV signals. These external receivers can be called an HDTV Tuner, set-top-box, decoder or DTV Converter Box . So you will be required to purchase a converter box to receive over the air programming from an external antenna.

Can not get pip to work

Pip has its own tuner, try getting a cable splitter to split the signal into the tv. If you have digital cable you may need a second cable box to do this. If your cable provider still sends an analog signal the splitter will work.

Cant program digital channels.

Nothing. Digital Tuners Broke. I wouldn't be suprised if your TV freezes up momentarily (or for a long time) when you switch over to the Digital Channels.

This TV has 1 tuner for analog channels and 1 tuner for digital channels. You can probably find the Digital Tuner on Ebay and replace it.

Sony projection tv with dual tuners; only one tuner appears to be working now.

To verify that the tuner is the problem, move the cable from the second to the first. If you don't get a signal, the tuner is bad. The main tuner is part number 859843000 and is available for $47.38 from

Misubishi warrior 2 intermitant pic freezes 1 second or less

Hello frogman,

The freezing of the picture denotes a loss of signal on a digital (Having a ATSC tuner) TV. If your TV is not digital (Having a ATSC tuner) then it is the device that you have connected to the TV (Cable Set-top Box, DTV Tuner, etc). In the likelihood that it is your TV I would suggest getting a better antenna first if that does not fix the problem you may have a tuner problem. However lets not look at it that way first. What we need to do is to determine if it is the TV of whatever you have connected to the TV.
First unhook the connection you have from the cable to your F connector of the TV (you should see snow or a blank screen) connect a antenna to the F connector of the TV, do you see a snowy picture or a clear sharp picture (snowy= NTSC tuner, clear-sharp= ATSC tuner). If the tuner is NTSC then check you cable device and the connection between your TV and the device and the cabling between the device and the wall. If the Tuner is ATSC then you will have to check all of your connections, and finally if the tuner is bad it has to be replaced by a qualified Tv repair shop.

I hope this helps,

Thank you,

Off air digital signal

What brand of tv is it ? You could have a bad tuner or a change in the voltage supply line feeding the tuner . What type of antenna do you have ? outdoor or rabbit ears ? Also does it retain the channel line up or does it clear them as well ?
