Hi


Thanks for using FixYa. This is often caused by failed convergence ICs. I don’t think the issue is with the power supply of the unit as the sound is coming fine from the unit. Also please check that the lamp is fine. Resistors will change value and burn. This will cause other components to become defective. This can have a domino effect and cause other parts to fail. Replacing one defective part may make the TV operate for a short time but the part will fail again since if the parts that caused the failure to begin with are not replaced. The typical cost to get this fixed by a pro is about $300 - and it doesn't mean that he/they will do a job better than you do. The parts are less than $100 (about $20-$30 for the IC's) if you want to do it yourself. If one IC is shot the other one is not far away and for that little price of the chips it worth changing them both at the same time. Also the convergence board should be checked for cracked solder. If you replace the ICs and the resistors are shot, the ICs may blow again almost immediately, meaning you may have to do the repair twice. Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Mitsubishi VS-6041 60 in. doesn't power up


Hello Tremulant

This denotes a possible problem with the Low or high voltage power supplies. The clicking you here might be the shutdown circuit acting because of excessive draw of current. The problem will most likely be associated with the HV power supply, but you will have to have a qualified TV technician check your TV to make sure.

I hope this helps,

Thank you,

No video but good audio Mitsubishi VS5051. Check R509 and R 519, 100 ohm resistors located on the main PCB near the flyback transformer. Also bad connections on any of the yokes and the vertical output IC will cause the same problem.
