Question about Panasonic PT-40LC12 40" Rear Projection HDTV

1 Answer

Television shuts down as if thermal problem, but cool

Television powers up, lamp lights, picture and sound. After 30 seconds (give or take), set shuts down. Both the exhaust and intake fans shut down; however, an internal fan blowing on a PCB beneath the lamp area continues to run. The lamp indicator light flashes 4 times every five seconds after this occurs. Unplugging the unit and plugging it back in twelve hours later results in the same problem. In fact, the internal fan I mentioned above comes on as soon as the unit is plugged in. Thank you for any help that you can provide. I was recently laid off and am on a bit of a shoe-string budget.

Samsung HLS5087WX/XAA DPL shuts down after 30 - 60 seconds, 3 blinking lights


I beleive from what you have told me that most likely it is just a lamp issue, there are a lot of so called original equipment lamps and counterfit lamps on the market that will barely give you 1000 hours run time. When it comes to Television lamps cheeper is not better. Make certain to buy an original Samsung lamp, you should get about 3500 to 4000 hours from it. If you need further assistance or have questions please reply to continue.

Temp light flashes tried unplugging it for a few minutes turned it on tries to power up but then power , lamp , temp lights flash for a few seconds then it shuts down and temp light stays on


It sounds like you have a thermal issue. The TV is getting too hot or the Thermal Fuse is bad. The thermal fuse detects the temperature in the TV and tells the TV to shut down if it thinks it is too hot. Most likely caused by poor ventilation or clogged fans from household dust. Try moving TV away from wall or cabinet first, if this does not fix the problem, clean ALL the fans in the TV. If problem still persists, replace the thermal fuse.

SOUND AND PIC GOES OUT FOR 30 SECONDS, THEN PIC COMES BACK THEN SOUND. IS THIS THE LAMP OR THERMAL FUSE OR WHAT.


The lamp is going bad. If it was the thermal fuse it would not be intermittent. It is very common for some Sony sets like yours to do exactly what you describe when the lamp is going bad.

Replace the lamp, also the shut down time is correct the unit must allow plenty of time proper lamp cooling. otherwise the lamp life will be greatly shortend. normal lamp life is 3000 hrs.
lamp replacement may require an internal limp timer reset have a qualified tech replace the lamp.
