Mitsubishi MB-62525 TV. Connections for RGBHV or VPrPb invalid.

We have a mitsubishi MB-62525 TV. All the settings appear to be fine. The error message showing on the screen reads: Check connections or power. The connections for RGBHV or VPrPb may be invalid. Is this repairable? I see alot of similar complaints on your site, is there a repair sheet you have for this problem?

    OK, so if I have the TV on Monolink to watch cable there is no picture at aal. Just the blue screen of death with a white lined circle or burst shape in the middle of the screen. If I turn the DVR player on and switch to inout 3 which the DVR is hooked to I get the "Check connections or power. The connections for RGBHV or VPrPb may be invalid." message.

    I have done that twice. I even called the cable company and reset the cable box.

Is a Signal Board the only possible issue?

The RGBHV error message refers to the HV guns Red Green and Blue. There is a board attached to each particular gun and these boards must be tested for damage. Usually this condition is terminal 80% of the times but we can try fixing it provided you have prior experience in dealing with HV electronics as this is a particularly dangerous repair.

    Right, there is Reset button on tv front, press it with some thing like paperclip tip, that reset might fix tv problem.
    And if problem remains same then its hardware failure and signal board is most suspected that got problem and need to be replaced by qualified tv repairman.
    Thanks.

We have direct tv, the other day while attempting to format our mitsubishi tv from the direct tv remote something went wrong and we lost about 20 channels from our regular and direct tv. Now when we swtich...


I would start with the DirecTV unit first and set the resolution back to 480i. This can be done in the menu or with a button on the front of the receiver, all modes are shown on the front of the unit. It's not uncommon to get that message when using the DTV input on MITS tv's, it's just a formatting glitch...but a bit annoying. Your set may not decode 720p resolution so I suspect those channels that broadcast that format may be your problem.

This model only has one HD input---it has two sets of component inputs on the back and one is marked 480/1080----in the menu it will be the DTV input.

Check to make sure you are not connected to the other component input.

Let me know what happens and let me know exactly where you are connected and what are using for signal.

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

Can you help with this error message: "Check connections or power. The connections for RGBHV or YPrPb may be invalid." Getting no picture for any devices connected to the screen.


There is a problem with the Component video cables and/or connection. These are the 5 RCA cables. Red, Blue, Green and two additonal cables for audio in red and white. Be sure they are connected to the proper ports on each end. Not sure what you have connected to the TV with these cables, but HDMI would be best. You also should have selected "Video" from the Input button on the tv's remote. Check these and follow up if possible.

Tv goes off, then comes on, and volume goes to max


OMG! Verizon Fios at it again with changing boxes! Well let me tell you if you do not loose signal on a DVD using these same inputs ITS NOT YOUR TV!

Whats going on is further into Verizon system you loosing the signal from the VDSL slam outside in the pill box. This thing will need to be replaced and they are going to blame your TV until you just give up and buy a new TV only to figure out its not your TV.

1. Call them back
2. tell them to check there network
3. if that dont work tell them to check it again
4. if you have HDMI use that instead of the scart connections.

I hope you have luck with Verizon Fios there internet rules but there TV service is sub par!

Thanks

Error message: check connections or power-the connections for RGBHV or YPrPb may be invalid. The screen is a two tone blue and is flashing.


DO NOT do anything to your Mitsubishi WD-52525 until you read 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 the past several years with faulty electrolytic capacitors (from Taiwan) that decay, dry out, swell and die. The power supply is often the first component to go bad, but other systems also degrade over time. As the forum explains , this problem is widespread in these sets causing multiple types of display problems after several years of use. Mitsubishi is aware of the problem and will cover most of the cost of repairing the chassis, even years out of warranty, but apparently ONLY if you get an estimate from a Mitsubishi certified repair station and contact their customer support BEFORE doing any work on the set. I just followed the recommended procedure on that forum and Mitsubishi is covering half the cost of my $700+ repair when my 3+ year-old set recently died and showed only a blue screen. I'm not sure if this is your problem, but it might be.

Code says check connections or power. RGBHV or YPrPb may be inval


Dunno. But if the tv has been 'reset' you will need to re-assign all devices (via NetCommand). Also complete the setup again to verify audio & video selections. If you can select "video" on the remote, you should see various video options...including brightness, etc. If OK...you need to get the right device assigned to the TV for viewing from cable box.

Mitsubishi Projection TV WD-62525


Could be quite a few things wrong. first I would do self test diagnosis and see what error you get, then check that area. It could be a bad Ballast or it could be Fuse F9a09 and the Light Engine. It also could be Caps C9a37 and C9a38. For additional info www.ctechnicians.com
