SOURCE: Dot & Crosshatch Generator question

this is a piece of equipment that injects a cross pattern signal or a dot signal (such as the little game connect the dots) and you align the colors exactly on the dots or the cross boxes such as you have already experienced with your cross hatches. i would think more along the lines of another resistor, connection, or something real close to where you already are, sounds like you almost got it just need to look one more time.
good luck stereo tech

SOURCE: Mits WD52725 DM Board

Dan,
I would causion removing the DM board in this unit. It is buried and the real problem is that there is many capasitors across all the boards of the chassi assy that could go bad. Replacing the ones on the DM will not guarantee fixing the dreadful green Blinking
LED. The only way I have known it to be fixed properly is to actually send the chassi assy. to Mitsubishi for them to refurb it. The negitive thing is that it is exspensive and they will only refurb it through aAuthorized Misubishi Repair Facility.
Cost would probly be around 800.00 to 900.00.
I know it is not what you wanted to hear,
but that is mt take on it.
Hope this helps,

Your symptom sounds like a damaged convergence IC, whick you have found to be true.

There are two and large IC’s that control the convergence in a big screen set. They are secured to a very large aluminum heat sink.

Along with the convergence IC’s there will also be some associated components that will need to be replaced as well. There are some resistors that are part of the convergence circuit that will be open and need to be replaced. Most likely these will appear charred in the center. If you have an Ohm Meter or a DVM, check all the resistors that are close to the IC’s and you should be looking for either ones that have opened or have changed values.

You will also want to replace the white heat sink2.gif compound that is on the heat sink2.gif, just scrape it off, then clean the surface with alcohol. Then apply a thin coating of fresh heat sink compound, if you do not do this important step the new IC's will not last long as the old compound will act as an insulator to the heat transfer.

I would suggest that you contact a service center in your area for a complete diagnosis and repair, as this type of repair can get a little tricky. But if you want to repair the set yourself, just remember to be careful. The capacitors and CRT’s can hold a charge and may shock you.


If one of the convergence IC’s are found to be bad, I would replace them both, if one has gone bad the other may go soon. I usually order my parts from Andrews Electronics in California, they will have the OEM components that you will need.
Their site is http://www.andrewselectronics.com/welcome.aspx
And their phone number is a 24-Hour Order Desk: (800) 274-4666
I recommend the phone order so you can talk to the person about the different types of IC’s that are available.

I would also advise that the convergence IC’s be OEM or better, just because they are cheap does not mean that they are a good deal. I have seen the cheap IC’s fail after a short time, even though they look exactly like the OEM IC’s. I think that the bottom line is that you will get what you pay for when it comes to the parts.

You can also try http://www.tvrepairkits.com/ , I have not tried them yet, but they do carry OEM or better parts.

I hope this information allows you to resolve this issue.

try this and let me know what you find:

Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} UNPLUG TV AND THEN PLUG BACK IN---TURN ON---GREEN POWER LIGHT COMES ON FOR A MOMENT AND GOES OFF.

PRESS AND HOLD “device” and “menu” buttons on front of tv for at least 5 seconds and then release both together.


Watch for power light to blink in a sequence:

1 blink-then 2 blinks-------no error

2 blink-then 1 blink-------X-ray protection

2 blink-then 2 blink-------SHORT PROTECTION*******

2 blink-then 3 blink---------deflection circuit problem

2 blink-then 4 blink---------vertical circuit problem


******2, then 2 is most common---usually means one of the fuses that protect the Convergence IC or IC’s is blown---set will detect no voltage to convergence IC and shut down.


SET WILL REPEAT BLINK ERROR CODE UP TO 5 TIMES AND THEN TO GET IT TO REPEAT MORE YOU HAVE TO UNPLUG SET AND TRY TO TURN ON AGAIN.


IF IT IS 2 AND THEN 2---USUALLY
CONVERGENCE CIRCUIT PROBLEM

You have a bad flyback transformer. This is a common problem that eventually goes bad in the ITC 222 chassis. You have to get the model number with the code at the end of it after the /. And sometimes you must have the numbers from off the flyback itself. Try to contact MCM electronics for the flyback at 1-800-543-4330. First see if they can match it with the model number with the code after the /.

Rca rear proj. 1993 model p46151wk tv just went dead no picture no sound no light on power button I only found 1 fuse it is good


Take a look at CR4118, and the capacitors around the power supply regulator chip. You likely have capacitors that are dried out. They can take out the chip, and Q4101, the 'chopper'.
The web site: http://eserivceinfo.com/ has a program for the CTC169 series of RCA projo's that is very useful in finding the fault that causes the condition you describe. Just enter ctc169 into the search box. Or go to this URL:

replace the keyboard or remove the switches for channel up/down to see which one is bad. if neither does it, there are some components around the microprocessor that can cause this.

You have bad convergence IC's.. If your not experienced in troubleshooting electronics or soldering, you should have a trained tech take a gander at the set. Its not worth risking life and limb to save a few bucks, Good Luck
