SOURCE: No picture on my Philips HDTV

possibly you have hit the vga button on the remote by accident. if you have, the red lite blinks and the picture goes off after a second or two. Hit the TV (not the power) button and be sure not to hit the vga accidentally.

Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

A local repair shop, recommended off ShopJimmy.com, repaired ours with the exact problem for less than $250 total. Inverters were bad. The parts were $50 each at Shop Jimmy so the shop dx'd the problem and repaired it for less than $250 total! Very happy.

Trick they showed us.... turn off lights in the room and shine a flashlight down the t.v. The picture can be seen which means it's not all the horrible problems you might think.

SOURCE: TV has sound..no picture

This is a projection TV. No picture can have a whole host of causes.
When the TV turns on, you can see background dimly but no picture.
Caused by the picture being muted. Perhaps the video signal is too fast - 1080i on a TV that does not support it might cause this.
Menu works but no image.
Definite picture muting. A bad video cable, no video from the device providing the picture. From the tuner, the signal circuit board needs repair.
No background, no image, no menu
This is a loss of high voltage to the picture tubes. If the picture cannot draw up and down or side to side, this will happen. Definite time for a repairman. Can be pricey if certain parts have blown out.
Most likely is a loss of vertical drive. (up and down drawing of the picture)

Screen is black after the initial white screen that displays "Philips" Sound there but black screen with no picture Menu does not show either Nothing but black


I believe a firmware update can fix this issue. However to be sure I would need your entire model number, including the numbers after the slash. You can put that entire model number into Philips support website, http://www.usa.philips.com/#/headernav/consumer/

Once you get to your TV's support page, you can look on the right hand side and find the firmware information. First I suggest you read the Read Me file to familiarize yourself with the update process and what issues it fixes. Then you can download the firmware to your computer so you can upload it to a USB drive to perform the update.

Hope that helps!

No picture,sounds and system operational


The vertical circuit may have its positive and negative supplies, but is the output waveform correct? I have seen many of those TDA vertical outputs open up and cause exactly what you are seeing. The + and - supplies are there but there is no output. Replacing the IC usually cures the problem.
