Question about Toshiba 36HF71 36" TV

Open Question

Distorted picture at top of screen

We are tied in with Brighthouse network cable service. When we place the channel on the GUIDE the top picture which shows upcoming programs is distorted, blurry and shakey.
The TV is about 7 years old. We contacted the cable company who came out to replace the box, but said it was the TV and not the box. We called a service repair shop who was knowledgeable on the type of TV we have and indicated it was some sort of conversion problem which would cost about $300 and another $150 to pick it up and return.
Is it worth it? are you familiar with such problems?

SOURCE: TV will suddenly change channels, change volume, or go to set up screen by itself

yes and this is a common problem! First lets check out the obvious/ when theis fault starts to happen take out the batteries out of the remote control. If the problem stops then you need a new remote. If the proplem persist the remote sensor assy is bad in the tv set. Ive never heard a cable box causeing a motherboard to act up?? Wait arent mother boards in computers?? lol. believe me you need to tell the tv msn to replace the rmote sensor. Now in an extremly rare cases the microprocessor was causing the problem BUT highly unlikly. Good Luck

SOURCE: Constant changes in picture colors.

It is a 20" TV set and will most likly, im afraid to tell you, cost more to fix then it is worth. The problem is a bad Picture tube, an intermittant CRT socket or the video jungle IC is intermittant. If you want to invest in an estimate, check out first if it will go towards the repair, as then maybe you can get it fixed at a good price, as long as the picture tube is not the problem Good Luck

SOURCE: Toshiba 35A44 - Dark picture on all channels and DVD's

for this brightness problem actually came out from flyback transformer...so, before you spend and waste your money, try to adjust at back of your tv first. But if you aren't an expert, better ask technician to do because that transformer supply a very high voltage....there's two adjustment point at flyback transformer, one point for focus and the other one for brightness! try first...

SOURCE: No picture, only sound

The set has a shorted vertical output IC, probably a TA8427k. The capacitors around the heat sink of this IC dry out and cause the IC to run hot. The correct repair is to replace the vertical output and the electrolytic capacitors near it. Also use 105 centig instead of the original 85 centigrade. The is some time a pico fuse or current limittng resistor which must also be replaced. This a common problem with Toshiba and is not a bad picture tube. The usual cost of this repair is around $120-150 depending on the integrity of the technician. Scrivitron

How to get full picture on my tv?


First, ensure your tv is using the highest resolution possible (Usually 1080 for flat screens) by using an HDMI cable from the receiver to the television, and that you are on the correct input. Second, ensure your tv is not sizing the video by using the 'picture size' or 'aspect' or 'ratio' key on the remote that came with your tv (Not your DISH remote). Third, tune your DISH receiver (with your DISH remote) to an HD channel (for VIP model receivers, when you tune the channel to an HD channel, an opaque white 'HD' appears insude the blue box at the top of the screen). Fourth, hit the star key on the remote, while watching the screen. On the right hand side, near the top, it will cycle as you hit repeatedly the star key, the style of screen widening. Hit the key as often as you need to make the screen appear the way you want it to. The receiver will remember your setting for all HD channels. When finished with the HD channel, tune your receiver (with your DISH remote) to a SD channel (any channel in the guide that does not have the HD icon). Repeat the fourth step.

For Hopper/Joey family receivers, hit menu, settings, screen size. Follow the instructions to resize your screen to match your preference. When finished, repeat step four above on each an HD and a SD channel.

I have recently bought a sony bravia model number KDL-40EX710. The input channel either keeps flicking to another input channel, ie AV1 to HDML or when on AV1 or AV2 the channel confirms itself at the top...


Your connections might be loose and the tv is constantly recognizing the connection over and over, that would explain the pop up. I would imagine the picture would be distorted somehow if that was the case but worth a try. If the problem persists after trying a good new cable then I would call the manufacture.

My brighthouse remote can turn my tv on and off but not change channels


The remotes have several device keys at the top of the remote. They have abbreviations like "VCR", "DVD", "TV", "CBL". By default some actions are locked into a specific key. By default, the volume buttons will always control the TV volume and the channel buttons will always change channels on a digital box.
If you have a digital box, and the channels wont change, the default locks might have been removed. Consult the instruction manual that came with the remote and re-lock the buttons to the correct device key. Otherwise you will need to press the "tv" button when trying to change volume and the "cbl" button when trying to change channels.
If you do NOT have a cable box and are just simply trying to use the universal remote as a primary remote, you will need to unlock the global channel lock. Consult the manual for the remote or check online for the remote guide. The Company which makes the remotes is called Universal Electronics and you can find digital copies of their manuals on the Brighthouse Websites.

Sound not picture


A few questions:
Are you using this TV directly on a cable line of do you have a cable box or satellite receiver connected?
Do you have sound and no picture on the AV inputs as well, or only on TV channels?
Is there anything on the screen or is it completely black? Has the picture collapsed to a single line across the screen? Is there a picture but it's distorted?
Does the on-screen menu and channel number display properly?

With a little more information I might be able to help you with this.

Screen is blank but can hear all the channels. cable guide shows up but no picture. What do you think the problem is


The video circuit section of your LCD needs service and this will require board level troubleshooting and by a qualified service tech. There is a light tube or floresent tube that excites the liquid crystals to give visual to the screen and it may have blown and needs replacement.

My Toshiba A205 started up with a distorted screen. The Toshiba start up screen has yellow letters on a green background. The blue log in screen has swirls of distortion. I can read the text in any program...


Try repositioning the screen in different angles. If it clears up even if only for a minute, the it is most likely the cable or ribbon cable running from the LCD to the motherboard. If not, It may still be a broken wire in the bundle or something more serious like the inverter card or the video chip. The wires on the bundle usually break over time at the point where the bundle runs up by the hinge of the LCD.

Aspect ratio problems on Samsung LN-S2651D Flat Panel TV


The aspect ratio (zoom) button on the cable remote had been changed. On Brighthouse the # button toggles through the zoom settings. It's not a tv issue, it's a cable fix.

Poor screen resolution and unable to get channel guide.


The channel guide is a service just like closed caption. Rumer has it that it's not going to be around for much longer. The only fix is to unplug set ..wait awhile till memory loss occurs...plug back up and do a setup. Nothing in the TV will cause partial guide. Weak signal could and cause fuzzy picture too. Complain to cable company. But brightness problem is something else.

Cable channels 5 and 6


not sure on this model , but check your menu and see under the setup menu if it has a band select option or tuning band. sometimes the autoprogram may pick up the wrong band. Make sure it is set correctly. I had this where it would just make some certain channels bad.
