Hello, flashing lamp light and error code 3-2 indicates lamp cover sensor switch is open.

There is a small switch located near lamp housing and will get engage when put lamp cover on it so please put rear lower cover back on TV then put lamp cover on it to close that switch OR close the sensor switch (blue color) manually to get the TV turn On.

I trust my input will help you out. Please feel free to respond if you have any additional questions.

Please recheck error code as 19 isn't listed in manual.

Have tried 2 lamps 1 that was in there that was good when it came out and 1 new out of the box.Power up and it gets sound for a few seconds but no fan.then it goes dead.Solid red light,yellow flashing , throws a 19 code ???Can these lamps be ohm'd out ?
Expert:  Shahid replied 1 year ago.

I understand that 2 lamps have been tried in TV, but the error code you're referring here isn't mentioned in TV service manual so either there is mistake in counting the light flashes or the issue would be any connector might be left unplugged or misaligned on board where DLP chip was replaced.

Please recheck the work done for DLP chip replacement and make sure all connectors are plugged securely and tight, please reply back with the result.
