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

1 Answer

High voltage shorting in the tube

Have sound but No picture. The high voltage is going to 40KV and opening the heater filament. The high voltage module is a stand alone high voltage generator with a 130 V supply and a control line for on and off. Has anyone had this problem? Why is Philips so had to get information from?

How to check filament in tv


If it has a picture tube first look with set on, three tiny filaments will be lit if good, not real bright as 6.3 volts ac voltage across two pins on the actual tube.

If you can see them lit they are ok---most sets mark them on the board at the end of the neck for the picture tube with H for heater.

Very carefully as high voltages on the board measure for 6.3 volts AC across those pins. If for example its 3 volts that is too low and the voltage from those pins can be physically traced back to the High voltage transformer creates it off two pins.

less than 12 connections between source and the board on the tube, if missing voltage at the tube follow it back--a single cracked or bad solder connection can cause this.

No video only sound on CRT TV


possible no filament lit in the neck of the picture tube (there are 3 and not real bright as source is only 6.3 volts.

Possible no High voltage but most that have sound have high voltage.

You are going to have to remove rear cover to LOOK--be careful and let me know what you find, if no filaments are lit it will be a easy fix and should be easy to find---if no filaments let me know.

Good sound no picture


A older set------look to see if display comes on (channel number or menu) if not someone has to look to see if the filaments in the three picture tubes are lit or not.

Several voltages : High voltage, screen voltage, filament voltage all go to the picture tubes.

CRT no image, sound ok. What could cause this?


WE can presume if static electricity on screen you have high voltage (most sets will not have sound if no high voltage).

If voltages appear to get good:

TAKE A CLOSE LOOK IN THE NECK OF THE PICTURE TUBE: all these sets the filaments in the tube should be lit when the set is on.

All are 6.3 volts AC (two filament pins on crt board--one is the ground and the other the AC--use that ground and carefully.

If no filaments or very very dim (they will be hard to see) the source for the voltage (if no or low filaments) comes from the high voltage transformer to the crt----usually one of two issues in this case---a part has opened or gone way up in value (resistor?)

It is a very simple circuit---just follow it back as usually on board that plugs to crt you will see something like H1 and H2. Follow both back and look for a broken connection or an open part between the tube and the source.

Let me know what you find and ask if more questions.

The picture went black but we do have sound. It was running perfect and picture was great until it just went black.


If this is a Toshiba 61A61 rear projection. First you have to determine if it has high voltage. You can find this out by looking at the end of each picture tube where the socket is to see if there is an orange glow indicating that the filaments are lit and the set has high voltage. If they are not lit then I know from experience with this set that there is a bad connection on the deflection board where the high voltage transformer is located. The HV transformer has red wires coming out of it. You will have to turn the deflection board upside down and look for the bad connection. But first just tap lightly on the deflection board with the handle of a screwdriver to confirm the bad connection. If the set comes on you will be required to solder the connection with a soldering iron and rosin core solder. Now if the orange glow is there you have bad capacitors on the hyper module. The hyper module is located to the right looking from the back and stands upright and is soldered to the main board. It will be required to unsolder and inspect the capacitors for bulging at the top. The hyper module is likely to not be available anymore. Changing the capacitors will fix the video problem

No pucture but sound


welcome to fixya

its mostly Sounds like you have lost video somewhere in the video circuits. Possibility is that the picture tube could have gone bad or lost filament voltage.
You can check to see if you have high voltage by holding your bare arm close to the screen. The hairs will stand up if you have high voltage. Absence of high voltage will also cause a black screen,but the sound might not work either since on some sets the power for the sound is supplied from the same circuit as the high voltage.

Try a hard restart, which simply means unplugging the power cord of the TV, and replugging it after 4 hours have passed. This technique reprograms the electronics, to a certain extent. If the picture does not return, then you have a more serious problem

do comment if it does or it doesn't help you ! we will try to help !

Bought a used ge46gw supposed to be fine brought hm 3days it went out, would work for 2-3 hrs at a time.....put in garage for a while moved it to another hse,now no pic at all sound is fine....where do I...


The reason there is no picture is (95%, certainty) the loss of the high voltage. The high voltage is what produces the energy for the raster lines upon which the video is modulated.

Therefore, the video and deflection circuits may be working just fine but you cannot see because there is no high voltage to the picture tube.

Now, it is possible, also that power to the picture tube filaments has been lost, or that the power supply to the biasing voltages is defective or that the picture tube sockets are corroded, but the overwhelming cause among TV sets is loss of high voltage.

Refurbishing the high voltage will probably cost $250 or from anywhere you go. Even if you do it yourself and buy the parts wholesale you will not save a tremendous amount. So, unless you are very handy and know how to troubleshoot, solder, repair and test, I think you are better off finding a good shop for the repair.

Replacing the high voltage regulator should fix the problem.

Good luck!

SOUND OK BUT NO PICTURE.


THAT MAKES SENSE, CHECK FOR HIGH VOLTAGE- YOU CAN SIMPLY HOLD A NY SMALL NEON BULB[LIKE THOSE USED IN PILOT AMPS] NEAR THE ANODE LEAD OR FLYBACK TRANSFORMER IF IT'S ACCESSABLE, AND IT SHOULD GLOW. THE NEXT STEP IS TO CHECK THE FILAMENT CIRCUIT FOR THE PROJECTION TUBES- OFTEN IN MODERN SETS, THE FILAMENT [HEATER]VOLTAGE IS OBTAINED WITH A COUPLE WINDINGS AROUND THHE FLYBACK. IF YOU HAVE HIGH VOLTAGEE, AND NO FILAMENT, A 'HACK' THAT WORKS IS TO USE A SMALL POWER TRANSFORMER [MOST FILAMENTS [HEATERS] ARE 6.3 VOLTS, BUT DOUBLE CHECK THAT- IF YOU HAPPEN TO HAVE ONE OF THE LESS COMMON LOW VOLTAGE HEATERS, AND YOU OVER-VOLTAGE IT, YOU'VE JUST DESTROYED A VERY EXPENSIVE TUBE.THE 2SD921 IS IN AL LIKEYHOOD THE HORIZONTAL OUTPUT, WHICH DRIVES THE HIGH VOLTAGE CIRCUIT. IF YOU HAVE A SCOPE, CHECK FOR APPROX 15KHZ SIGNAL AT THE EMMITTER OR BASE- BUT BE CAREFUL ABOUT THE GROUND LEAD- USE A 3 PRONG ADAPTER, AND DEFEAT THE EARTH GROUND OF THE SCOPE, OR YOU COULD DAMAGE THE TV'S POWER SUPPLY

Sound but NO picture


Hello ashleewith2e,

This sounds like a high voltage problem or a picture tube issue (burnt out filament). I would first determine if you had high voltage at the anode of the TV by using a high voltage probe. If you do not have high voltage then I would suspect the voltage doubler, the IHVT (Integrated High Voltage Transformer) or the Horizontal Output Transistor (I doubt this only because you don't have a power supply failure and I would expect this in a modern TV since the high voltage supply is tied to the low voltage supply), the more likely suspect is the voltage doubler. Second possibility I would check is the CRT socket board and CRT filament. Unplug the TV and with a multimeter set to read resistance check to see if the filament pins read a low resistance if so the filament is good. Plug the TV back in and turn it on and check the voltage on the CRT board and compare them to the schematic values. These two tests should localize the issue. Now, If you have a background in electronics, this should be no problem to do, however if you do not have a background in electronics, I would suggest that you have a qualified TV technician troubleshoot and repair this TV set.

I hope this helps,

Thank you,
