Question about Philips Magnavox 9P6034C 60" Rear Projection Television
Model# 9p6034 c102, serial# 33192207, ptv835
I have no picture and no audio. The green led on front works as if everything is ok. it flashes no code and the set makes no sound at all and un plugged for several days to reset its self at no unveil " Its dead". The fuse is good and i have the main board ( attached to the power cable) out right now. I am good with a volt meter and a soldering gun. I am in need of a wiring schematic ( service manual ) and some good advice. This seems like the place to get both. thanks in advance.
The screen is blank with no raster at all and there are indications that the channel numbers are changing in the display.
This indicates that some of the low voltages are present but these may be derived from the standby supply.
Assuming there is no deflection and no HV, you either have a low voltage power supply problem, bad startup circuit, or bad horizontal output transistor (HOT) or other bad parts in the horizontal deflection. Initially check for bad fuses. For further examination if you are familiar with electronic repairs, you will need service manual to proceed or call an authorized tech service. http://servicemanuals.vstore.ca/product_info.php/pName/9p6034/cName/phillipsmagnavox

The set has gone into protection overload status.
You must unplug the power cord for 3 or 4 hours and power it up again.
If the hard reset above does not bring it back to life it needs technical service. There are about 10 sections that would need to be checked to see where the overload conditions are causing the problem.
As a general rule this type of failure is severe and expensive. Typical costs of repair are always over $200 and most often closer to $400.
Common failures are main power supply, high voltage supply, deflection amplifiers and so on.
This is not a user or home remedy type repair. If you are lucky it may be something not so costly, but experience tells otherwise.
