I just inherited a Mitsubishi 6043A and it has a couple of problems. Initially, the picture was OK but had vertical bars that appeared to move down the screen (not too distracting, but noticeable). Also, it sometimes powers up without picture. I can hear sound, but the screen stays black. Turning the TV off then back on usually fixes this problem. It happens when the DVD player is on before the TV. Today, the picture lost most color, and appears sepia. It seems like a loss of blue. Any idea on repair costs or ease for DIY?

Re:
Sounds like many different problems maybe related thou. You say 6043a but you are under WD-62327. So this info is for that.1. Suspect the Light Engine part # 939P977020 also you could need.. Suspect the Signal PCB part # 930B923002 if no video keeps up

HI, Your tv has problem with its vertical scanning side. vertical scanning
output ic (integrated circuit ) may have some problem ( faulty or dry
soldering in its leads). You can easily find out the vertical ic on your tv.
there will be four wire coming from the coil which is fitted on the
picture tube neck, of which 2 will goto horizontal scanning section and
the remaining two will go to vertical scanning section. just follow the
two thin wire (normally in color green and yellow ). it will goto a
socket on the main board. follow the track on the board. it will lead u
to vertical scanning section. check for any dry soldering, if not ,
replace the ic. ok
No,this tv 100% have convergence problems,it dead.Any colors lines R,G,B are mis alignments,have colors shadows pictures or 3D pictures look alike?The tv convergence board have dead 2 STK convergence ICS and some or all of it resistors are dead too.These parts on the tv convergence board,must be replaced to solved the tv pictures convergence problems.The shop,will cost u like $300-350 for parts and labors.
It has been my experience with that model mitsubishi that the usual culprit is loss of vertical sweep. If the beams in the picture tubes stops moving up and down this is detected by the micro processor and the video is blanked, but the set is not shut down. The usual cause of loss of vertical sweep is bad solder connections on the deflection yokes or a failed vertical output IC.

This model is equipped with a self-diagnosis feature to help with diagnosis of shutdown problems. To activate this turn the unit on let it shutdown then press the input/device and menu buttons on the front panel simultaneously and hold them in for 5 seconds after 5 seconds the power LED on the front panel will blink a two digit sequence. This will be one set of blinks a short pause then another set of blinks, this will repeat 5 times. 1 - 2 = no error detected 2 - 1 = X-ray protect (high voltage or beam current) 2 - 2 = Short protect (short protect monitors low voltage supplies) 2 - 3 = Deflection protect (this could be loss of vertical or horizontal deflection) 2 - 4 = Vertical protect (usually loss of vertical from the source.

First check for fluid on the PCB's, if ok check the following:

SELF- DIAGNOSIS INDICATE X-RAY. CHECK FOR A SHORTED IC5A03 PART # 270P704010 AND AN OPEN R5A73 82K ¼ WATT OFF PIN 2 OF IC5A02 ON THE MAIN PCB. 2. SELF DIAGNOSIS ERROR INDICATES SHORT PROTECT. CHECK FOR OPEN FUSES F9A04 AND F9A05 PART # 283P043090 ON THE +24 AND -24 VOLT LINES. IF THE FUSES ARE OPEN THE CONVERGENCE OUTPUT CIRCUIT WOULD BE SUSPECT. 3. SELF-DIAGNOSIS INDICATES SHORT PROTECT. CHECK FOR A SHORTED IC4B01 PART # 270P261020 (VERTICAL OUTPUT) LOADING 24-VOLT SUPPLY LINE. LOCATED ON THE MAIN PCB.
Good Luck, big IRISH.
PS If too much call an authorizedservice center and have them give an estimate on their repairs in writing.
This set is known for some very common problems some of which is just what you described. For a small fee, I can give you some common solutions that will take care of these and other issues. The only problem is you must know how to take things apart and put them back together without doing further damage, AND you must know how to solder /desolder components.
To be honest, your bulb probably went out if you're missing colors, or they are slowly burning out. I'd say check behind your screen while it's on. If that's the case, those are usually 100 bucks a piece. I've said this on many problems so far, but if that's not the case it's most likely the color "tubes" in the back out of wack. There's a way to adjust it from the remote but if you can't get it back to normal they may need replacement which is very expensive. I'd say if it comes to it, get it checked (usually 20-50$ for a house call estimate) and if it seems like to much, search around your local want ad for one with a broken screen or something and just use your parts in a different TV. (www.criagslist.org is usually a good place to look)

MAY BE INTERMITTENT, SELF-DIAGNOSIS ERROR 23 OR 24. CHECK SOLDER CONNECTIONS AT CONNECTOR "DY" ON THE YOKES. 2. SHUTDOWN AT POWER WITH SELF-DIAGNOSIS ERROR 23 OR 24. CHECK C411 2200 UFD 35 V AND C412 10 UFD 50 V, BOTH LOCATED ON THE MAIN PCB.
