    oh i thought you could adjust the pincushion on that tv from what i have seen online




  • dcxguy48080 Dec 03, 2008

    if this can not be adjusted like you said in service menu

    can you direct me in what to test or what to look for in trying to repair this or should i just toss the tv away

    thanks


  • dcxguy48080 Dec 03, 2008

    do you know what areas to look for this on the board for this tv?? and also what percent chance do you think it is a bad capcitor or diode i mean is this a common problem?

    and what is a diode and what does it look like i know what a capacitor looks like

    this is a toshiba made in 2000 32 inch

    if it is a capacitor is it an inexpensive reapir for me to do i can solder......


  • dcxguy48080 Dec 03, 2008

    thank you

    one last question i have always wondered ....is it ok to store a crt or projection tv in the garage during the winter when it goes near zero degrees

    i mean is there anything that the cold can damage or not really

    thanks




  • dcxguy48080 Dec 03, 2008

    when you say leaky diode what am i looking for...actual liquid??? color??

    and if you had to guess would it more likely be a bad capacitor or leaky diode or 50/50

    thanks


  • dcxguy48080 Dec 08, 2008

    hi i opened the back of the tv and looked for any swelled capacitors
    around the HV didnt find any........how do i know a diode is bad or
    leaking??



    and also do you know exact locations of these diodes/capacitors for the picture bowing in on the left and right side??



    thanks

  • dcxguy48080 Dec 11, 2008

    how do i test a bad diode

    the capacitors do not look swelled at all


  • dcxguy48080 Dec 31, 2008

    none of the capacitoes are swelled..........whats else can i check?

    how do i check for leaky diode????

Sounds like a bad capacitor in the deflection circuit or a leaky diode which is causing the problem. Adjusting wont help.

    the most easiest would be simply look fr capacitors that lok swelled and or leaking. Without a ESR meter theres no way to test them, but often they swell especially on the top when they are defective

    The capacitor should be near the HV generator ( Flyback) Diodes are blck with a silver band on one end looki like a resistor. Diodes and capacitors are very inexspensive if you can find which one is defective.Be careful around the HV section cause even after a set has been unplugged for a while the capacitors can still shock you if youre not careful around them

Toshiba TV - no full screen


You need to go to the control panel in your computer and change the display resolution. The two resolutions are not matched is the only problem here. Find out what the native resolution is of your tv and match it in your computer.

The image on my Toshiba 24V4210U tv is cut off on the left and right sides. Also, the Info shows 480i whereas the input from the service provider is 780p.


If closed evenly with a shaded area on each side that is the 4x3 format, I can look but so can you: some of the sets (Toshiba) are only 4x3 and not full screen (16x9) and to boot only work with HD on one input.

480 I or not is not HD.

YOU Using a box of some sort here for this set?

My 32inch tv turns on but the picture is wired.


On a 32 inch it may not be worth fixing--not going to be a reset etc--base decision on fact that possible repair should not exceed used value of set--which in my view it likely will.

I have a 32 inch Westinghouse LED slim tv. I try to put a attena and it ask me for a 5 digit access code . I have no idea what's the code. Can you help me.


You have to go to http://wdsupport.net/wdeonlineservice/tunercode.aspx to get the access code to unlock the ATSC tuner. Find your TV model in the list on the right then enter the serial number in the box. The code should appear below that. You can also request a copy of the access code by email. If you have any problems, call the Westinghouse customer service line, 1-800-701-0680, during weekday business hours.

I hope this helps.

Lost 1/4 of the screen


Check the settings to make sure that it's dead and not just aliened wrong if it's a CRT. If it is dead, not a whole lot can be done, it's all done on a single glass plate. you may be able to buy a replacement LCD.

Phillips TV with no on screen menu, only Caption, Text and Sleep. bought TV's from factory auction. PA5032-C102. or 32R505-00BB.


The OSD (on screen menu) is locked. Those two serials (not models) are for two completely different tv's: the first is for an very old standard 32 inch CRT and the second for an old plasma.
To unlock it in the first tv you need to just press the menu button for 10 seconds. For the second tv you must start the tv and immediately press both the menu and channel up buttons for 5 seconds.

I dropped a Samsung 50 inch T50875 on the ground during a move yesterday. The exterior screen is intact but the inside looks at if it is filled with broken glass. The top of the screen displays unviewable...


this could be the bulb that is inside, if this had a huge back to it then it could be the monitor that has broken inside. I would take it to your nearest tv repair place or back to where you got it if they have a repair there and have them take a look at it. some will give you a free estimate and come to your home since it is big.

Toshiba television and universal remote problems


Hi, as the sets get older the codes for older models get deleted to make room in the remotes memory chip for the newer models, this is probably why none of the universals will work for you, post the model number found on the back cover of your tv & I`ll look it up to see if theres a sub or the original is still available, video-tek

Philips universal remote codes


The website you can go to is http://www.urc.philips.com/. Drove me crazy looking for this website and you must know the first three letter infront of your model number of remote for instance mine was us2-pm435s. Share this with others.
