Question about Philips 60PP9202 60" Rear Projection HDTV-Ready Television

1 Answer

DPTV335 Ok - Here is a hard one for you.  I have a DPTV335 with audio but no video.  When I powered it up and noticed a blue arc in the blue CRT tube neck. I wanted to test the tube in another set so I put it in my old Philips PTV835 that I had in the garage. The PTV835 was working prior to the swap.  I powered up the PTV835 with the suspect CRT and nothing lit up - all three cans remained off. I then put the original/working CRT back into the PTV835 and powered up the set. To my surprise the whole set is now dead. I have no HV as far as I can tell.  My question is as follows... 1) On the PTV835 - What do you suspect I damaged when I put the defective CRT into the set? What typicaly gets fried from a shorted CRT? 2) On the DPTV335 - Same question - What gets fried when a crt shorts out.  Thanks in Advance, Ed

    Thanks "Slinteriors".

    I moved the whole crt - yoke and all over to the PTV.  I will check the vertical and horizontal

    Question - On the DPTV

    I will check the vertical,horizontal, and hv generator also. But before investing in a blue crt I want to get video working again. 

    Is it possible get video working on the other CRT's without the blue crt connected?  

    Or do all three need to be connected and functional to get video?

    I assume I can just removed the blue circuit board, hv, and other cables...but not sure if this will work or not. Any tricks here?

Ed did you change the yokes when you put the DPTV series CRT into the PTV chassis? If not its most likely the vertical output or the Horizontal output that got destroyed. If you changed the yoke its most likely the HV generator.
On the DPTV chassis that should shutdown the vertical deflection which would leave audio working worse case scenario would also be the HV generator and Horizontal output.

check the high voltage with the screen control turned up high where there is no raster. suspect problem within the video circuit where there is no high voltage or defective picture tube.some time when the screen is black and the screen control advanced,you can see if the tv has video or vertical or horizontal problems on the screen.service the high voltage circuit if there is no raster or high voltage is raster can be caused by the no heater or filament in the CRT.---- a defective picture tube can cause many problems, such as, poor brightness ,missing colors,intermittent picture,poor focus,a single-colored raster,arching in the gun assembly,retrace lines in the picture,negative picture,chassis shutdown,noheater or filament lit and no raster to name a open filament or heater can cause no picture or no raster symptom.a defective CRT can have an extremely bright screen.loose particles of the cathode element can lodge between the grids and cause an intermittent black and white picture. simply tap the ends of the CRT gun assembly and notice if the picture begins to flash off and on.---- with a leaky picture tube after turn on the raster dims and get extremely bright.a dim picture with no green in the raster can result from a bad green assembly. a heater-to-cathode short can cause a raster to change colour or a result in no raster at all.replace the picture tube if there is severe arching in the neck of CRT. excessive brightness with retrace lines and a vertical collapse to a thin line can be caused by a bad coil on the neck board of the picture tube.rejuvenate the picture tube when there is very bright green screen. check for the resistance change on the resistors of the CRT neck board for an excessively bright picture with retrace lines.excessive dust inside the CRT spark gaps within the picture tube socket can cause the very bright raster and the chassis shutdown.a defective video amp,luminance buffer,or reference transistor can cause a bright picture with retrace lines. -------- for getting any required parts to replace you can get it from or from or from --------- thanks.please do rate the solution.thank you for using fixya.keep updated.

Sony kp-57HW40, screen flickers with blue tint, then shuts off

The problem with you set is: focus block and(or) intermittent G1 short in a blue CRT(picture tube). To determine the tube failure, you must take front panel off, rectangular cover under it and gain access to CRTs. You will see 3 picture tubes with wiring and boards attached to them. on a bootom of the set there is a black plastic box with 2 rows of 3 potentiometers on raw is for the focuses, the other one is for the screen controls. it will be written on the box with letters R.G.B. first: take a light isolated handle screwdriver and tap very slightly on the neck of the right tube. Do not brake the glass! That's the blue CRT. It might have a blue color sticker on it or blue socket. Tv must be on and running, while you perform the test.If your tapping on the neck makes blue flashing, your CRT is bad, if not, try to play with blue "screen" potentiometer by turning left and right, slightly. If that will cause the blue flashes and hard to adjust, replace the unit.
Good luck,

D52W19 No pix, sound good - now green light blinks, no come on

First of all you need to find out which CRT leaked and replace it before any other repairs are done. The clear liquid is conductive and has done damage to the CRT board or boards.

Sony KP51W40 Blue tube flashes

I do not think the old tube rejuvenator will do much if the HV is arcing. The CRT it might leaking some coolant or some moisture from it is causing the arcing.
I would suggest to read the info from this website to re-seal it or replace the coolant.
Let me know if you need further assistance.

Blinking red power light - set will not turn on

Were the pale blue lines real thin in a slight diagonal from bottom to top of your screen? If so you either have a bad component in the blue drive, Blue CRT socket or your Blue CRT is shorted.Try removing the blue CRT socket and trying to power up your set for a moment without the blue socket attached to the tube. Be sure the CRT socket doesn't touch any components when you try this. Let me know if the set starts up without the blue.

Magnavox 8P6051C101 Projection TV Problem

Changing the tubes isn't that hard. However your blue tube is whats causing the green and red to over power your screen. Magnavox blue tubes frequently need the Crt Coolant changed especially in the blue CRT. It has a tendency to gel up like oatmeal and it will actually make it next to impossible for the tube to function properly. You can easily check this. Be careful but look inside the blue tube while its playing you will notice right away if the tube looks real cloudy compared to the green and red tubes. This is a repair that most "handy" people can handle with proper instructions. Hope this helps let me know if I can assist you further.

Color off for first 60 seconds...

you have three color tubes in this set and they are RED< BLUE, Green, I would check 200v line going to CRT's. You may just have a loose connection. you can move around slightly and see if you see a change. Be carefull thou, not to damage anything else. Check to see if CRT boards are on neck of tube(press upward slightly) Hope this helps
