I have a Panasonic Model PT-50LC13 flat TV. Was working when got it brought it home, it is used and now when I go to turn it on --- we get a green light then a flash of 5 yellows blinks then no light for...

This tv has 3 indicator lights on front, Power, Lamp and Temp
I assume Temp light is blinking 5 times after every 5 seconds, if that is correct then it is problem of clogged air filter located in light engine that need to be cleaned.
Below is an image of light engine and air filters locations are marked with red circle, it is job of professional to fix this issue because complete light engine need to be take out from tv cabinet.
Hope these info will help you, let me know if you have additional question or need service manual copy if you want to repair tv by yourself.

I have a Panasonic 52lcx35. I contacted Panasonic, and they sent a repairman to "repair" the green spots we were seeing (this was the only problem). He did something, and afterwards, the tv only turns on...

amber weaver,

It sounds like the repairman forgot to reconnect one or more of the fan motors. There are several in these units and if not connected you will get the error you mentioned. Unplug the unit and remove the back. Locate all the fans (this may take some time to make sure you have them all).

There could be 3 or 4. Check each one's wire to make sure they are all connected to wires or an appropriate board. If this is your problem this should solve it.

Thanks for using FixYa and for the great rating!!

Panasonic projection TV does not turn on.

Power LED flashes orange 1 x 5 secs. = 1 of 3 fans stopped. TEMP LED flashes 1 x 5 secs, = Temperature error. Lamp LED flashes 1 x 5 secs. = lamp ballast error. (check lamp 1st.)
Hope this helps.

The 3 blink error code is indicating that the Convergence ICs have failed. You can get the repair kit for your model which contains both convergence IC and the six feed resistors and it also has step by step instructions with pictures that show how to do the repair. Heres a link to the repair kit for your model.
