Question about Mitsubishi VS-5043 50" Rear Projection Television
Upon inspection of the mentioned areas I discovered a burned spot on the board at IC9A1 near a 2 watt 2.7 ohm resistor R508 and QA543 which all have overheated solder connections. IC9A1 and QA543 both have bad connections to the PCB cicuitry. There appears to be another resistor mounted too close to the fuse in that area and looks to have touched the fuse terminal. There is a carbon deposit on the lead, such as an arc. Your input has been very helpful in narrowing down the search and I thouht you might like the findings. One note: I could not locate R510. The circuit may have been modified slightly
Not uncommon in a mits and more likely due to some caps that have exceeded their ESR. That still doesn't make this unit unrepairable, mits were built to last. Find a good reliable shop and take it in... You can use the NESDA web site to locate one unless you have that worked out.
