Question about Samsung TXT3093 30 in. Television

Open Question

My tv screen is hourglass shaped (bowed-in on the sides)Samsung TX-T3093WH I took the back of the tv off and found four pieces of plastic. After looking a bit, I found that the ''color alignment rings'' on the back of the tube were loose. I noticed that the plastice pieces held the rings in place and now they are free to move. I noticed marks on the rings and realigned the marks and the colors on the screen were pretty much aligned except where the screen is stretched at the corners causing the hourglass shape. Does anyone know how to correct this? I love doing the repairs myself to save money and I just like repairing things. I am hoping that if something requires replacing that I might be able to do it myself. i am also looking for the service manual for the tv, SM-TXT3093WH. I also found that with the TV off, I can use my remote and push the following buttons in this order to get to the tv setup features; mute, 1, 8, 2, power button. Thanks for any help that is provided.

I just had my lower Y-buffer board swapped out to fix a problem similar to yours. After an hour and a half of on-time, the lower half of the screen would flicker on and off with the same appearance you mentioned. Changing out this particular board fixed it for me. However, since it has gone from top to bottom on your set, it may be more of a main board problem for you (that controls both upper and lower halves). Beyond this, I don't know any more. I am considering getting a service manual to gain more knowledge about the various PCBs in the unit so I can fix any future problems myself.

Do not automatically think you need to go into the service menu. I bet you 100 to 1 that you pulled out a plug or a connector somewhere OR one is not seated into the plug all the way. If the set worked with color before you messed with it, there is not a problem in the service menu. The service menu is not the fix all thing. it is there to make fine alignments and adjustments, and as a matter of fact, messing with a service menu even with the service manual is very dangerous. I have seen peeps ruin TV sets by messing around with the service menu alignments. STAY out of these alignments. they are not going to fix a problem that all of a suddenly comes up. Repair the problem in the circuit first. Good Luck

Set TV to standby and press Info, menu, mute then power. The set should turn on with the service menu available scroll down until you select reset press right hand arrow next to enter and then enter. TV will turn off. When switched on it goes into Plug and Play mode to reset the analogue and digital tuner. Allow a full reset then you should be ok.

It does sound a lot like a buffer board problem, Just which one is the question. Sometimes it is in fact a connection issue. But 1/2 of the screen missing sounds like maybe connection between the 2 buffer boards. It could possibly be the panel. If that is the case. ITs over for that set. But i would suggest first calling samsung and asking them to extend the warranty for 90 days or so. Sometimes they will do this for nice customer such as yourself. 1-800-SAMSUNG. Let me know how this turns out first then we can proceed further if needed. Good luck and keep me posted. Sincerely Jay

Get the tech supplier to tell to the manufacture and the store what he told you.

Physical damage on any electronic device is very hard to have serviced under warranty. I have never seen a plasma display crack on its own. But, anything can happen.

I once saw a man drop a newly bought plasma TV in a parking lot outside from where he bought it and the screen broke. He never even made it home from the store!

Maybe you should contact a lawyer or someone who can give you legal advice about how to proceed with this. In different countries and different states the consumer protection laws are different.

TV comes on but after a while there becomes a hourglass shape on screen. It is drawn in 1/2 inch on the sides. Can this be fixed cheap?


yes. has a pincushion circuit problem. since tv works and then starts to bow, its a bad solder connection. when tv warms up the metal expands and looses connection. when cold, the solder constricts and unit works fine. just solder deflection area. you can probably tap on board and locally find area to solder.

Hourglass shape on left and right side-ballpark repair price please


The shape your seeing is called 'V Bow' and 'Pincushion' which needs to be calibrated again. Theres probably a diode that went out. The tech can open it up and adjust the angles back. I wouldn't charge over $100-$150. Shop around for a good repair tech. Good Luck poe_diddley.
