SOURCE: Unexpected lamp shutdown

Remove the lower front panel by removing the 2 large round screw heads at the lower back corners, one on each side. Remove the retaining screw on the right side of the metal horizontal retaining strip in front of the bulb holder, remove bulb retaining screw in the upper left corner of the bulb holder. Pull the bulb holder out towards you and check for dust build up on the top screen on the bulb casing, if there is an abundance of dust it will restrict the airflow across the face of the bulb which causes it to heat up and turn off. Once the dust has been cleaned your bulb should now work as it should without a problem.

SOURCE: How do you find the

Carefully remove the back of the TV. If you have a grounding strap, wear it. If not, always keep one hand on the TV and use the other hand when ''rooting around'' back there to prevent shock damage. The power supply will be large, and very heavy. Here is a link to what it could look like - this link is a list of all possible power supplies in your model along with photos. http://www.shopjimmy.com/catalogsearch/result/?q=42PFP5332D+power

Once you find the power supply, locate a part number on a sticker or the board itself and match that up to one of the power supplies from the link. Leave the power supply inside the TV until you have the replacement in your hot little hands, so you can remember how it went in etc.

Home stereo Phillip 708/37 is not getting power.i was told that I need to replace the transformer.cam you advise me how?


maybe not, are the fuses ok ? check fuses, make sure they are ok, also some transformers has a thermistor in between the winding of the transformer in series with the primary winding. Phillip do make their transformers with that kind of protection, just in case the transformer over heat it shuts down. examine the transformer look for the thermistor it is open.

Phillip you have a problem in the main power supply or in the High voltage shutdown circuit. Now the longer you wait to have this fixed the more its gonna cost ya Unless your a tech then get a schematic and measure the voltage on the hv shutdown pin on the video junglke ic when the set shuts down If the voltage at the time of the shutdown sodent spike up then you know your problem is in the power supply. Good luck
