In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Polaroid model 3211tlxb sept. 2007.ec18 on the power board gets very hot and tv shuts down. i have replaced ec18 and q16 no help


Hi mrdink010,


I've checked my service manual collection but I don't have the copy on this model. I've also search it online and to my links of the service manual but I can't find one to view the schematic diagram of your unit.
The power supply gone to excessive heat due to over current flowing on its circuitry. This is caused by faulty parts like the transistor, IC's, diode, resistor, capacitors, transformer on its line that in most cases have a partial leak. This is hard to diagnose and needs the skills of an expert to determine which part gone bad. Usually this is not caused by one parts only but most of the time multiple parts gone to malfunction.

I would advice you to replaced the entire power supply board rather than troubleshoot this kind of symptoms because it will cost almost the same. Click this LINK(http://www.shopjimmy.com/polaroid-860-az0-mlt666amh-power-supply.htm) for the replacement. Double check the actual part no. of your board that is printed on the white sticker on the board itself before ordering online.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

power board 15-860-az0-ipos150h capacitors or to light weight they heat up and burn out replace with heavier capacitors if you dont know how to do it take to tv repair fixed mine very cheap works great now unplug tv take off middle black center section after u unscrew it push black panel downward take off only three screws remove metal panel the board that has the defective capacitors is the top one that your power supply cord plugs in to remove board dont touch electronics of the board because of static electricity in your body take board to have capacitors replaced or pick up some at radio shack and replace them yourself soldering iron is required to do the work yourself
