TV Repair Questions? Ask a TV Technician
there is 2 ,11 volt fans and 2, 21 volt fans they are not all bad do you you have a volt meter or would you be able to g o to Walmart and get one for 10 dollars
1. Is there any trick to getting into the back of these TVs, or is it just a matter of finding all the screws?
2. Will ground wire be a specific color code?
3. Just to clarify, if I unplug the bad fan, the TV will turn on, but i need to replace the fan to prevent the TV from overheating?
I only remember two fans on this unit, but the reason is, the fan that causes the most problems is the lamp fan. Its a squirrel fan that sets on the lamp housing and one on the back of the TV. The most common failure is the lamp fan. Here is an illustration of the fans I am familiar with.
The back fan is easy to replace, but the lamp fan, requires a lot of caution - as you need to remove some housing and connections to get to the fan - you can damage the TV more.
If you want some detailed instructions, I can provide them. But a repair cost would run about $300, mostly labor - unless its the cabinet fan.
