Panasonic TV slow to turn on, works fine after it turns on.


If you have to try to turn it on several times it is power supply related.

If dirty inside on fans etc it would cause set to shut down(the set monitors the fans for speed)>

I would suggest (take it outside) using a air compressor and cleaning the entire set out.

Lamps do fail---average life is 2000 hours for a original lamp and much less for a generic one.

If picture comes up try to watch the light from the lamp---if dim at first and then slowly comes up---it could be the lamp or the ballast the set uses to power the lamp.

Replaced lamp on Sony KDS50A2000 and now it shuts off and on every couple of minutes. I used the Menu-Settings-Lamp command and no change. The green light stays on and the sound is also still on. The lamp...


Hi,
Your tvs lamp is getting over heated. There will be a fan for colling the lamp. if the fan doesn't work properly the lamp will get over heated and the will switch off itself to avoid further damages. Do one thing, Remove the fan from the tv. In the fan there will be a specification sticker. Remove the sicker. Now you can see a hole in the center. its the bearing part of the fan. put one drop of oil in it. You can use any type of lubricating oil. rotate the fan leafs with finger for some time. after that re-stick the spec sticker. insert the fan in the tv. power ON the tv and watch. If the fan is available then try to replace the same. it will not cost a lot. just watch the following video for oiling the fan. its for a PC fan same for all dc fans.
ok

Sony wega 55 inch tv turns on fine but after one minute tv shuts itself off and comes back on 40 seconds later by itself and this cycle continues - none of the error code lights blink


This kind of problem occurs when lamp becomes weak that means near to end of working life hours but still not dead nor broken.
Replacement of lamp in tv will solve your problem, lamp replacement procedure is easy and would be written in user manual.
Thanks.

Samsung dlp tv turns on works fine but after 15 minutes turns itself back off


This happens due to increasing heat in tv, check exhaust fan is running and throwing hot air out of tv, check temp sensor is working fine mounted on lamp housing.
When did you replaced lamp last time in tv?
A weak lamp also does same problem.

The thought is that it needs to be either cleaned out. Dust build up in it's air intake filter or you probably need another new lamp. Usually when these set's shut themselves down is because they are overheating or they can't maintain the voltage to keep the lamp lit.

The lamp light does not have to flash on this set for it to be the lamp, and most likely it is just that, the lamp. These sets when the lamps get weak they will do exactly what yours is doing.

TV shuts itself off after a couple minutes of being on.


One must be very careful of the quality of the replacement lamp. Many of the cheap 'deals' on the web for replacement lamps are substandard. I always recommend that replacement bulbs be the original manufacturers bulb.

Standby LED flashes red 4 times with pause then 4 times


You either have a bad fan or one of the rotation sensors mounted on one of the fans has failed. Take the back off the set and see it the main fan slightly right of center is rotating. If it is, there are two more fans, one mounted right above the lamp and another on the optical block itself. You will have to pull the optical block to check those.
