    Thanks for your help Raystv934. I took your advice and went out today and bought a new 52" Samsung LCD. No sense wasting any more time and money on the old set.

The most common problem with sets was the high voltage transformer which to my knowlege is no longer available. I had a source for good after market transformers but that has even dried up. Sorry for the bad news.

I have a Mitsubishi CS-35405. It has worked fine up until yesterday. When I turned it on the sound was fine but the picture is very blurred and the colors are pretty much all red and green. I tried the...


As old as this set is I worked on a lot of them.

Red and Green only?

These sets among other things with age develop bad solder connections: I suspect on the board that plugs onto the end of the picture tube you have some broken solder connections--the red, green, and blue video output circuit is there.

The really hard part with this set is just getting it apart--weighs a ton.

Let me know if I can help (not picking any set that heavy up).

I have a Mitsubishi CS 3515R 35" Tube TV. The screen has narrowed at the top and the bottom so only about 2/3 of the horizontal screen has picture. There are black areas at the top and bottom....


There are two issues, the first is a vertical deflection problem, "needs a few parts+an ic" the second problem is intermittent color, "crystal and color processor ic" If the set is close to 10 years old then your money is better spent on a new tv.

Flatline!


the vertical drive ic that drives the yoke for vertical sweep has blown.
sometimes it is solder problems like sharp and toshiba had.
the part is 10$ the pc board will label it ,the yoke is the coil setup on the picture tube.if you follow the wiring half goes to the horizontal drive,and the others to the vertical section.the chip drives the coil directly.there are VERY high voltages in there ,even turned off. the pix tube cap on top is 30000v. like a stun gun.the horizontal drive 2000 volts and the main power supply 165 volts dc high current.you need a special setup to discharge the picture tube.

CRT TV Screen Colors Off


The tv needs degaussing (demagnetizing) unplugg the set tonight and then plug it and turn it on in the morning. You should hear a a "bonk" noise when the set is first turned on after being cold- this is the internal degausse circuit working and it should fix your problem if you don't hear the "bonk" sound or it does not fix your problem call arepair shop to have the degausse your set and possibly fix the internal degausse circuit.

Black screen and no sound


I realized that there is a 90 day warrantee on parts and a 30 day limited warrantee on labor for the  repairs that were done. As I stated, the original problem was the picture shrinking after a few minutes of the set being on. The repair firm took my control board with them. When they came back to install the repaired control board in my set there was a load spark during the installation, after which I had a black screen and no sound.  The repair firm took my set them and installed a "CAP Kit", a STRM6511, and a "D1881". The set worked perfectly until two days ago.
I called the repair firm an they are coming out this Thursday to check out my TV.   I am hoping the problem is related to the failure of one of the parts installed to fix a similar problem which occurred after the sparking incident.

Mitsubishi CS-40707 Greenish/Yellowish Display


Yeah, I had mine checked for the same thing. The "blue" - There's only three - red yellow blue- portion of your tube died. Not repairable. Last I checked it costs at least $1,000 for a new 40 inch tube. Good luck. Mine went to the garbage dump!

Black Screen with sound


make sure the TV time is correct. Reset the time. if that does not work, but the TV operates ok, it's in the circuit board, or could be a fuse problem.
