hi you are right this is common fault what needs replacing is the convergance ics theirs 2 of them but whils replacng these you will need any resistors checking for damage also as when the ics start to fail then its usually because a resistor has blown somewhere on the board causing the power to rise or fall and this causes the ics to fail
If this happens to all the input sources, the main logic board is fired. If this happens to only one input source, only that input source circuit is fired.
It is costly to replace the main logic board. And then there are other components ready to die out soon.
Your set is at least 5 to 6 year old. Have you replace the lamp yet? It is rated for 10,000 hours. Yes, it will fail in about 10,000. Off brand replacement is cheaply made, can cost problem. (mine did). The nut holding the wire to the lamp was loose.
Time for a new TV. A new 46-47 inch LCD is less than a grand.
That model Mitsubishi is a 65 inch set not 55. And if the blinking you are talking about is the Power LED continually blinking green and otherwise dead it is because the digital module is not booting up. I have repaired many of them and this is done by replacing components in the digital module. Average repair cost is around $200 to $300 depending on where you live. That particular set is well worth the repair. If yours is a 55 inch instead the same still holds true.
Yes it is possible to replace the panel. I would suspect that it is cost prohibitive however. I am willing to state that the cost of the panel will be close to if not more than the cost to replace the TV.
trust ME when i say setting convergence after doing repair takes alot of time to do /you can damage set if you do not have service codes and values/ you also must have the hand unit that comes with set in order to even get into convergence circuit, call your repair shops ask if they have a good blue tube for set and how much would it cost to repair?ARE you sure blue tube has been removed from set.?
if convergence problem color would be bowed and off. If it is the convergence replace ic stks there are 2 inside tv if you could solder and good at this stuff. parts cost is 30.00 . if you are going to get fixed cost is 300.00 . www.part store.com has parts just give them model number .They can tell you part number.I would pay someone to do this it is trickey.
I think ghosting is ground problem on cable connections check connections and replace cable wire.
Have you checked the lamps. Rear projection TV's have bright lamps, that can burn out. If you have had this TV for a while, that is the first thing I would check. If you still have to manual, it should tell you how to check the lamps and which ones you need to order.
These should be special lamps only Panasonic sells. Therefore they might cost a few bills.
