    My set is the Panasonic PT-53WXD63G . First sign of trouble appeared with double image of channel numbers and then the squeezed picture, and finnally lost picture, but have sound. Now when I power up unit, it clicks once with several beeps after (maybe 5 or 6 times). It continues this with an on and off cycle untilI I power off the unit.

Cant find how to remove the stand on our newly purchased Soniq QSL323CT1 anywhere in the manual. We are trying to mount it on the wall.


Hi,
1. Disconnect all cables.
2. Cover a level and stable surface with a thick and soft cloth.
3. Gently lay the TV, face down, onto the cloth. Make sure the Table-Top stand is hanging over the edge.
4. Rotate the cable holder 90 degrees, and pull it out completely.
5. Remove the screws (3 or 4 in rear next to cable holder, depending on which model wall-mount kit you have) being sure to hold the Table-Top-Stand firmly while removing the last screw.
6. Do not remove any other screws from the TV.
They also say not to remove the stand for any reason other than wall-mounting the TV. Their should be instructions with the wall-mount kit.
Hope this helps!
Thanks
Smith.

Cant disconnect two red cables inside my panasonic projection tv


I'm assuming you mean the high voltage lines.
All you have to do is reach in to the front block' and grasp the red line that goes to the flyback.
Do not attempt to remove the fly back side.
Just be careful not to bump the CRT's.
Slide the boot off and pull!

Tip of LANC connector on Sony tripod broken off!


Two options:

1. Replace the cable with the same connector.
2. Replace the 2.5 mm connector.

I took the LANC cable from an old Sony remote, open up the tripod remote control handle and replace the whole cable. Some soldering required to remove the wires from the PC board and solder the new wire.

The PC board has marking White/Black/Red, the replacement connector with the Tip to the White, the Ring to the Red, and the Shell to the Black.

Good luck!

How to remove red cables from "tower" on rear of board?


Don't!! the red cables are the high voltage and focus lines. damage to these will disable the set! However, the board can be removed far enough to facilitate repair without removing these cables. They are usually held in place by plastic loops. release both cable from each loop they go through pull free from chassis brackets. the smaller one goes to the focus block in the front of the set (behind the speaker grill)

Tv doesn't turn on, just bink a red led light seven times


Replace your Tvs convergence board. Go to www.partstore.com, and check for your current TVs model number. Check for its convergence board, and simply install it by carefully removing the old board that looks just like your old one, and replace the cables where the cables for the old ones were. In many TVs, the cables are gray, blue and 3 multicolored sets, which go to connectors marked blue, green and red. The gray and blue go where the gray and blue cables for the old board were. For the multicolored ones, just replace them where the previous ones were placed, marked blue, green and red. All you need is a screwdriver and about 30 to 45 minutes.

Toshiba 52hmx84 shutting off


When the bulb on one of these Toshiba DLP units burns out, the unit will show a blinking green and a solid red, and restart itself 8 times, then show blinking green and red lights. A replacement bulb costs about $200 and is very easy to replace. If you replace the bulb and the symptoms continue, the problem is probably the ballast. The manual and Toshiba support will direct you to an authorized service center, but if you are ambitious and want to save the expense, here are instructions for replacing the ballast yourself. First, many thanks to those of you who have done this before me and posted elsewhere. There was a request for pics of the ballast board install, so here it is.

FULL DISCLOSURE AND WARNING: YOU ARE ON YOUR OWN AND I WARRANT NOTHING FROM THESE PROCEDURES. I AM NOT A TV TECH. THERE ARE SOME VERY HIGH VOLTAGES IN THE BACK OF A TV BECAUSE OF THE LARGE CAPACITORS. BE CAREFUL. THERE ARE ALSO MANY DELICATE CABLES AND CONNECTORS IN THE BACK OF A DLP TV. PROCEED AT YOUR OWN RISK! IF YOU ARE UNCOMFORTABLE WITH ANY OF THE STEPS, CONTACT A TV TECHNICIAN IN YOUR AREA TO DO IT!

You will need:
1. A slightly long standard head Philips screwdriver.
2. A leatherman or small pair of pliers.
3. The Toshiba service manual. Refer to it often if you get lost. - download it here.
4. The ballast board (Toshiba Part Number: 23122468). I got mine from Conn's in Flordia here.
5. Some tape or a marker to label some of the cables so you don't forget what went where.
6. Patience. Lots of it. smile.gif

The Steps

1. UNPLUG THE TV! Put the TV somewhere so that you can easily get to the back of it. You'll need at least 3 ft of room behind the TV. REMOVE THE LAMP ASSEMBLY NOW.

2. Remove all of the screws on the lower part of the TV. Set the cover aside. It should look like this:

fc5ad1b1.jpg

3. To get an idea of where we're going, as you look at the back of the TV, just behind the fan and lamp assembly is the ballast board, looks like this:

a1b14510.jpg

4. Next, remove the screws from the silver brace arm in the middle and the bronze screws that hold the light engine assembly. This brace is attached to the ribbon cable by a Zip tie; you do not have to cut the Zip tie if you don't want to. Refer to the service manual if the pic below doesn't show the screws clearly, but it will be obvious when you are looking at the "light engine sled".

9b694bf2.jpg

5. Remove the bronze screw holding the plastic shield that angles down to the lamp. This screw is kind of hard to see just looking at the back of the TV, it is located up and above the ribbon cable attached to the back AV board.

18abb633.jpg

6. Using a small pair of pliers, squeeze the plastic nipples in and push the cable hangers out of the plastic shield. Remove the shield carefully from the back of the TV and set aside.

7. Slowly and very carefully, remove the copper ribbon cable as shown. This copper ribbon cable was the hardest thing to put back in during reassembly, I kid you not. I hate that ribbon cable with all of my soul. Next, remove the yellow, blue, and red connectors as shown. If you forget where they went, the connectors are different lengths and only go to one and only one receptacle.

fd248cd9.jpg

8. Slowly and carefully, pull out the light engine assembly. There are 2 yellow leads that power the lamp assembly that you can remove if needed. To remove them, slide the rubber footing off, and you will see a very small clip, push the clip back while pulling on the lead and it will come off. If you do take the leads off, be sure to label them with a marker or some tape. Mine were quite stubborn in letting go (I didn't see the clips under the rubber footing before this posted), so I left them on. If you do leave them on, be carefull of the stress on the cable going around the lens assembly. I removed the cables from the plastic do-hickey holding onto them and moved the yellow cables to the front of the lens assembly.

9. Next, slowly pull out the light engine sled and turn it so that you have access to the ballast assembly, like so:

2b19530f.jpg

10. Noticing how filthy your ballast board probably is smile.gif, remove the two screws holding the ballast board.

13f0edf4.jpg

11. Now, remove the 2 connectors attached to the ballast board like so:

e2e3539a.jpg

12. Next, gently push the plastic tabs holding down the ballast board to the light engine assembly and gently push up the ballast board to loosen it from the plastic tabs grip. There are two other tabs on the other side. Now you'll now be able to remove the ballast assembly entirely to install your new board.

8d8ac6b6.jpg

13. Now, on the other side of the ballast assembly is the lamp connector. Remove the screws as shown.

ee3d4539.jpg

14. Gently turn the lamp connector towards you to remove it; notice the orientation of the connector so you install it correctly when you put the new board in.

a92acb87.jpg

15. Now, install your new board and put everything back together in reverse order. This would also be a good time to take some compressed air and blow out all of the dust in there. Take your time during reassembly and be very, very, very carefull connecting everyting back together.

16. Be sure to put the back cover on, and re-install the lamp assembly before connecting your inputs and powering back on.

17. That's it! If you did everything carefully enough, you should be enjoying your Toshiba again and just saved about $350! Congrats!
