I have the same tv and had the same problem.
If picture appears when you slowly hit back of the tv, then the solution is quite easy.
1-There are 2 small lids on the back of the tv, open the one at the top with using a screw driver.
2- there is a connector on the top, make sure that it is connected well.
As far as I understand there is somehow a connection problem or maybe result of oxidation or something.... westinghouse ld-3235 picture goes in and out - 5_3_2012_9_06_22_pm.jpg5_westinghouse ld-3235 picture goes in and out - 5_3_2012_9_06_54_pm.jpgclass=5_3_2012_9_06_54_pm.jpg

Common problem on this model. The Wires connector are good but the solder on the green board is bad. Often cold solder joints between the metal onboard connector and surface of the daughterboard. I had gotten a order of 15 of these Dead/no Video/Intermittent video. 11 were repaired with this method.

SOURCE: Good picture for 30 minutes then colors change!

Bad LCD controller, see sample here (note, I removed the cover off the board so you can see it): http://s807.photobucket.com/albums/yy352/budm/LTV-32W3HD/

Parts: http://www.shopjimmy.com/catalogsearch/result/index/?q=ltv-32w3hd&stock=all

Be real careful when you remove the back cover, the side switch assembly is attached to the back cover, so do not yank it too hard!

SOURCE: Westinghouse LTV-32W1 Plays for awhile then no sound or picture

could be two thing the new ps board you put in was defective or the inverter board is failing

Posted on Dec 07, 2009

SOURCE: Westinghouse LCD TV SK-32H540S, 1

1 swollen Capacitors / Replace
2 blown Diodes on inverter board / on some # 508 or 908
3 bad transistors in inverter bad will appear overheated powdery coat
4 replace inverter if you cannot locate problem on it
there is a safety built into the high power back light supply and that is if too much current is drawn or light is shorted it will not burn up
or hazard high volt shock to user.
capacitors and diodes driven with power transistors
look for darkened spots on the board to identify hot transistors
puffy tops and leaky bottoms of capacitors

when you turn it on does the bottom or top of the screen show image a Milli second before the other it should be evenly the lag
is the one requiring more amperage

Do the menus work or input labels appear when you change sources?
Have you tried unplugging the power with the tv turned on, waiting a few minutes, then plugging it back in and turning it on?

If the set is still under warranty, the power supply board is going bad. If not you can replace it yourself. It's not that big of a job. You can find the parts you need at www.shopjimmy.com

Westing House LD-3235 will not scan


It could be the tuner but you have a few options.

First is unplug the set and or a cable or sat box and wait a while. Plug back in to see if set/box will reboot.

Another option if you have or get a Box is get one with the audio/video output jacks on the back and connect it to the same type on the rear of your set-----Bypass the tuner and operate via that input changing channels on the box.

Westinghouse ld-3235 led tv no picture


t con board on the back of the screen will need replacing, its the one with the wires going to it from the main av board to the screen. the chip can become damaged due to heat or even come away from the board. if its working when you bag the board it could be a lose connector or the connections that is soldered to the board have come away and will need soldering back on.

Westinghouse 27" lcd hdtv


My Wesinghouse 27" lcd hdtv jumps and vertical hold is out of control after being on 15 mins. The cable company checked the connection and it is clean. We did not damage the tv. It has been doing this since we got it. We did not get a service contract. Sometimes the screen goes black with a small rolling picture on top. Help me please. Can the maufacter still help us?
we lost all the papers when we moved.
