Hi and welcome to FixYa,

A known common problem on this models (Chassis TAC0263). A couple of ideas you may want to consider:

  • DIY (do-it-yourself) repair, perform board replacement as mentioned by welcomejee, HYPER Board, Part Number PD0264A;
  • perform component level repair. Most common faults are 10uF 16V capacitors, a good number of them. leaky, dried or blistered. Should you opt for this, it would be to your advantage to have access to a service manual or at the very least a schematic diagram with voltage readings;
  • this of course would require opening the unit, perform voltage measurements, determine faulty component and subsequent part(s) replacement. Further, a fair familiarity of electronic components/circuitry and safety procedures, use of a DVM and a soldering iron would be required;
  • should you be uncomfortable performing a DIY, perhaps your best bet would then be to seek the services of a qualified professional;
  • if the cost of repairs and downtime would be factored in, then you may have to re-evaluate your options and consider a replacement.
The page and here may offer additional insight as well as a pictorial illustration on performing a DIY.

Good luck and Thank you for using FixYa.

This could be a component failure or even just a bad connection. Given that this occurred in the past and corrected itself, it suggests that the problem may be connection related. If you can solder, look on the boards for any solder connections that appear to be grainy or have rings and resolder them. If that fails, update this and we'll start looking for component failures

    There is a problem with the convergence ICs. Either there are bad
    connections (resolder the pins) or the ICs themselves are defective.
    Replace them if resoldering does not correct the problem. These ICs
    are large black ICs with about 15 pins attached to a heatsink. THey
    will be marked STKxxx

Is the TV sited by a speaker or other magnetic device. Magnets cause this sort of problem. Can easily be shown by putting a magnetised screwdriver close to the front of the screen.

Is this an old tv? When I worked in the trade I used to regularly gave to take a degaussing machine out to the home and run this over the set.

Failing that maybe the set is just shot!

    NO IT IS NOT THE COMPONENT, but the television needs de-gaussing. This is a device that produces a high powered magnetic field to clear this sort of problem. Generally your local tv repair man should be able to sort it, but it does involve a call-out charge.

    Has the tv been dropped or hit hard? If so the tube may be damaged beyond repair.

    This can be repaired by rubbing large magnets across the screen.

Seems like a board gone down ... or going to fail ...

Not really a lot you can do, except weigh up whether it's worth getting a shop to fix it or just buy a new TV in the January sales.

1Look through your manual. Your manual will always give you the most specific directions for your particular model. Look for an "adjusting convergence" or "set manual convergence" section. Step2Enter the menu on your TV. Use the remote control and bring up the menu. Step3Choose "Convergence." This may be under "Picture Settings," "Function" or "Advanced Options." Step4Select a color. You will have red, green and blue to choose from. Do each one, starting with red. Step5Press "Enter." A crosshair pattern will appear on your screen. Step6Adjust vertically. If there is a horizontal red line visible, press the up or down arrow keys (or channel up or down) to adjust the convergence until the line is superimposed on the horizontal-center line of the white crosshair. Step7Adjust horizontally. If there is a vertical red line visible, press left or right (or volume up or down) to adjust horizontally. Do this until the line is superimposed on the vertical line of the white crosshair. Step8Save settings. It is important to save your settings when you are done, instead of simply exiting the menu. Step9Repeat these steps for all colors.

Hi,
Try just plugging one input in and try that. Sometimes it's an interference conflict between inputs.
It could also be a faulty connector.

Toshiba 50H81 very dark, blurry picture on all inputs.


check if the problem looks zig zag looking or it its not present in the PIP window. If so this may be an issue with the hypermodule - you can google TV repair Kits to find parts.

I have a toshiba 52 in projection tv Model number 50H82 and the picture is really blurry with lots of vertical lines


If your TV looks 3D, warped, or distorted it likely has a convergenge problem.
If however it just looks dull, washed out, redish, or if it looks like objects on the screen have halos the fluid in the lens has soured.
You can search google for parts or you can get the parts with repair instructions from sites such as www.TvRepairKits.com

Issue with our Toshiba 50H82 - overnight it has stopped playing DVD's properly - a solid black rectangle obliterates 75% of the screen. Any idea?


Hi,
Do you see same solid black box in all inputs or just in dvd picture?
If solid box appears only with dvd picture then its generated by dvd player, check dvd player Menu and turn off any subtitle settings.
And if solid black rectangular appears in all inputs of TV like cable etc then check Close Caption feature in TV and turn off CC function.
Hope this will solve your TV problem.
Thanks.

Toshiba 65HDx82 video problems


I had a similar problem with a similar model by Panasonic. Unfortunately you will need a certified tech. to pick it up and repair it at there shop. It cost me around $400 bucks and when I received the TV back the remote no longer worked and the repair shop did not man up to the fact that they where liable. They just said they would order another signal reciever for the TV and never did. So, good luck. It is reparable just be careful who you deal with.

No picture, no sound, but has power light...any suggestions? thx in advance


Do this first:


1: Check the antenna/cable connections.

2: Press the TV/VIDEO on the remote control or the TV to view a signal coming from another device connected to your TV, such as a VCR or
video disc player. You can select ANT 1,
VIDEO 1, VIDEO 2, VIDEO 3, ColorStream HD1, ColorStream HD2, or ANT 2 depending on which input jacks are used for connecting the devices.

*Be sure you have the right source to view video.

Try the above and post back before I can say there is a problem with your unit. If you have the user manual it's a good time to get it out. If you don't have it let me know and I will give you a link to obtain it. Good luck!!

Toshiba Model 42HM66 DLP Projection TV


I strongly doubt it's the lamp assy since you can actually see the blue screen. If the lamp failed, you would not see anything on the screen. This blue screen indicates to me that either the tuner is no longer decoding the signal, in improper input has been selected (ie: input 1 is selected while actual signal is on composite 1), or something of that nature. If you are getting audio then the input is selected properly but the video decoder has failed.

If your cable signal is going through a VCR or DVD, disconnect it from there and go directly to the TV (ie: bypass the VCR/DVD). If your picture comes back, there's some kind of problem with your VCR/DVD player.

If you have multiple inputs, try connecting an input signal to another input (ie: video 1, or aux from a dvd player) and see if you get a picture there. If you do get a picture, the whatever input you're currently using has malfunctioned.
