Mine did the same thing. It was too much money to invest in old technology. I chucked that baby to the curb and got a 42" LCD. LOVE IT!!

Replacing the whole board will fix it, but is a bit of overkill. If you can solder and feel comfortable working inside the set, you can fix this yourself. Let me know if you wish to attempt the repair and I'll proviode additional details and instructions.

you probably have a problem with the convergence board.

not enough power, you may need to rebuilt or replaced the power board

I will need the chassis number in order to help with this model set.

After 11 years???? OMG This set is a tired pup and should be put to reast. My experience with older sets and your complains are all capacitor problems and is only gonna get worse as the first time around repair will take several capacitors to repair. This set has no user serviceable parts inside so you should not attempt a repair suchj as this on your own.. This repair if you decide to go through the first time will be About 300 to 600 bucks the first time and cost will continue to raise till the sets put to sleep. Good luck

Good Day, limao247;
Your TV may fluid on the PCB's. Remove the speaker grill, the small panel and look closely for fluid on the boards towards the front. Always unplug the TV for your SAFETY. If you find fluid clean board with acetone. Good Luck, big IRISH.

does not sound like convergence have had a few with bad capacitors. any good at soldering

A rolling picture or loss of vertical sync can be caused by several components including a bad signal board or jack panel assy. You will not be able to resolve this yourself. contact a Mitsubishi authorized service center.

The signal board is not likely to be the cause of this. I'll research this a bit and update this with some sugestions. Can you solder?

Thanks for giving me an opportunity to help. Could you give me some more information please? Are you trying to get the code to program a universal remote, your Mitsubishi remote, or your cable/satellite remote. If all you need is the code, here it is.

The code for a Philips DVD player is: PHILIPS ............. 441 442 943

If this code solves your problem, please rate my services. Thanks for using FixYa.com

yes it can be fixed depending on your model number if its the VS50605 they have a kit to repair the PIP module which controls vertical sync (Rolling) or you can bypass the module to correct it but you would lose the PIP function. Let me know if you need more info.

If this Hand unit is not a universal Remote there is No set up codes for it,It must be Factory unit you have ,you can buy remote unit with codes at Dollar store for 5.00

If TV will not come on when you press power on front ,then you have something wrong with TV.If Remote is problem you can go to dollar store and buy another one with code book to program TV with for 5.00. you may need to replace your STK ICs?

Replace the convergence ICs your model uses two STK392-040 Convergence ICs. You can get replacements at the following link with instructions.

The power supply caps in the light engine power supply were faulty when they were installed. You need to remove the power supply and take it to your local electronics shop where they can remove the (7) faulty 1000uf 16v electrolytic capacitors and insert new ones. If you remove the power supply yourself (takes only a philips screwdriver) and reinstall it yourself, the electronics shop shouldn't charge you for more than an hour worth of time. The caps would be about $10.

Here's a photograph (thanks Don Crawford).

The most common problem with this set in the start up circuit of the power supply. There is a resistor, a 270k, R903, and even if it checks or looks good replace C920. Also there are small resistors off the flyback transformer that will open up because of bad capacitors feeding those circuits. Also any capacitor that has a swollen top or body, replace. Double check and make sure the B+ fuse is not blown. If it is, before you replace it, check to see if the horizontal output transistor is shorted. If it is, replace the transistor, BUT intall a 100 watt light bulb across the blown fuse. If , when you turn on the TV set, the light bulb glows bright, one of the deflection yolks is probably shorted. Unplug the set, and pull out one of the yolk plugs. tun back on the set. If the light now glows dim you have the bad yolk. If it does not and is atill bright, unplug the set, replug in the yolk, and take another yolk plug out. Do in this order and replug back in the tested yolk and make sure you unplug the set each time you do this or you will cause more problems. goos Luck. Please do not forget to rate this thread.
