Question about Toshiba TheaterWide 52HM84 52" Rear Projection HDTV-Ready Television

Open Question

My Toshiba 52HM84 has no picture but only sound. Looking at the LED code; the Red is on and no green blinking or anything.. Just like the TV is normally ON. Last night while watching a show intermittently I heard some pop/click/tick sound and the picture was gone. Just after that, the LED showed green flashing at 1 sec interval with RED ON, but after few seconds it was just RED ON and no GREEN (like normal TV ON). So I switched OFF the TV and waited few minutes and turned it back ON, but still the same thing,. No picture only sound, with RED ON and no GREEN. I searched different forums to see if this was lamp issue, but people suggest lamp issue when the GREEN is blinking, but that is not my case. Please help.

SOURCE: Initially No Picture when Turned on but sound normal and 5 minutes later Picture is all RED and then Picture becomes NORMAL (all normal colors)

theres a high voltage block that all three of the anode leads attach to and sometimes a small crack happens across this block and will not let some or all of the crt's get the high voltage all at once untill it heats up a bit. now if this is not your problem i would make sure that all three crt sockets are attached to there tubes all the way as maybe justy maybe there loose and will only work after ther expand a bit. Now another problem that could cause this problem to occor origially would be that someone left off a crt ground strap and the crt arched and popped and caused the problem with the High voltage block. And no I cant see a tube being bad then comming on at first UNLESS when you say the red comes on is the picture all red with small retrace lines(small white lines)in the screen with no picture except for red???? No video only a red blank screen is what i mean. If thats what its doing then yes Ive seen heater to cathode shorts on a picture tube that would cause this problem but to be sure your really gonna need to have the set looked at.. Good Luck

SOURCE: Red?Green picture

If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.

SOURCE: 52HM84 Toshiba DLP with apparent failed lamp (replaced ballast)

I found R3 on the original board to be open, along with reading an open on CR1, D5 and D6. All the other transistors and the transformer check out. The only thing I have to do now is find out the specs of the diodes. The replacement board also had CR1, D5 and D6 open (R3 was OK). There had been some threads on various locations where remanufactured boards had bad components (the transistors were changed but not some of the other components).

I have a Toshiba 52HM84 and the picture has gotten really wavy, what can I do?


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired.

Convergence problems are very common on all Projection TV sets including Sony,Samsung, JVC, Philip Magnavox, Panasonic, Akai, Pioneer, Hitachi, Zenith, and others. You can get a convergenece repair kit wiith instructions from the links below.

Here are some of the most common problems with these sets...

Problem #1) Convergence

Yours may have one or more of the following symptoms
  • Screen Looks 3-D
  • Colors wont align
  • Screen may look distorted or warped
  • No Audio/Video - makes a chirping sound.
Problem #2

Another common problem is dull or washed out video.
Your TV2_bing.gif may have one or more of the following symptoms....
  • Dull looking picture
  • White looking picture
  • Halos around objects
  • Red/Orange looking picture

Problem with Toshiba DLP Projection TV Model #52HM84


It is possible the lamps may be defective or that they may be the wrong replacement for this model, as it may have a different wattage setup with the ballast. If you want to try to order the TB25 lamp from a different vendor, you can order the original Toshiba replacement lamp for this model (52HM84) from a major Toshiba parts distributor at the link below:

Screen remaining black after the TV is turned on

TV has sound but no picture


It is possible one of the internal fuses blew out.
It could be a bad horizontal outut transistor.
It could be a bad secondary of the power supply went bad
And many other things.
If it's just a fuse, it won't cost much, but a lot of them do not look like you would expect a fuse to look like.It might be a little yellow, green, or gray rectangualar box shaped part. :D

Red light flashing while green light stays on


I have the same TV, your projection bulb has quit/failed.

A loud pop was heard and the picture has gone followed by a red led fault light clicking on and off.

if your tv is less than 1 year old, and you registered it with Toshiba, you could qualify for a free replacement.

otherwise expect to pay 200.00 for a new bulb from Toshiba.

only good thing is you can replace it yourself, only tool needed is a phillips screwdriver.

you can check EbaY for prices less than 175.00 to 150.00
i am on my 3rd bulb within 4 years....

good luck!
