I have a 2000 Mitsubishi VS-45607. I am experiencing horizontal black lines, which make it look like you are viewing it through venetian blinds. The tv gets better after it has been on for a while. Is it the DM board?

convergence problem

OK this problem is caused by a failing electrolytic capacitor back in the power supply. It's job is to filter AC interfence from that voltage source. Locating the correct capacitor is something not for a do-it-yourselfer. A respectable tv shop experienced with Mitsubishi tv's can usually repair this problem in your home. Average repair cost would be between $200 and $300.

sounds like a defective cappacitor or leaky diode in the deflection circuits. Unless youre comfortable working around the high voltage circuits of a rear projection set, it may be best to call a reputable repair facility that is famillair with mitsubishi products.

Good Day, Delano1981;

It may cure the problem but I would suspect the 9 Volt source
CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND
IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH
ARE ON THE SIGNAL PCB.

This should resolve your TV"s condition.

Good Luck, big IRISH.

Sounds like the blue crt is either shorted or one of the resistors on the blue CRT PC board is open

i think the grid lines have been enabled.

and so disable it to having the problem solved

Just got this fixed. The problem is the 21 (yes, 21) main capacitors. It'll only get worse if they aren't replaced. The whole screen'll start jumping, multi-hour "warm up" times until you get a clear picture, maybe not even then... it isn't pretty. Just nip it in the bud now, and more power to you if you tackle it yourself. A good repair shop ought to be able to do this for under $400 if you can't.

Oh good, two people. I was getting weary of attempting to slightly change my answer for all the other people who didn't use the "has the same problem" feature. Anyway, the problem both of you have is not too far gone yet, but will get worse if you let it. It's the main capacitors. Maybe not all 21, but probably at least half of the 21 main caps are shot. All should be replaced at any rate. Any shop worth it's salt ought to be able to do this for you for under $400 if you can't do this yourself.

You can find you answer here on the threads at mitsubishi problems, I have answered may questions on this set, so in order not to keep repeating I would ask if you check other sets with this problems and try the same thing. Thanks, Hope this helps!

CHECK C2P08 100 UFD 16 V OFF PIN 3 OF IC2P03 (3.2 VOLT REGULATOR) ON THE SIGNAL PCB. HOPE THIS HELPS!
