UPC code85948500222


Hi. I'm not sure if this will help you, but I found this website:

UPC Database Item Lookup

According to this website:

"Enter the all digits printed on the UPC bar code, including any numbers to the right or left of the bar code itself, even if they don't line up with the main row of numbers. This should be 13 digits for an EAN/UCC-13, 12 digits for a Type A UPC code, or 8 digits for a Type-E (zero-supressed) UPC code. Anything other than 8 or 12 digits is not a UPC code! (And just because it's 8 or 12 digits doesn't mean it is a UPC.) You must enter every digit here.
If you have a barcode scanner that outputs plain numbers, you should be able to use it to enter the UPC number here."

So, apparently you need more digits to complete the bar code #. But if you have the full barcode, you should be able to enter it on the website linked above, and find the image of the frames that you are looking for. I hope this helped. Thanks!

TV screen Flashes blue and then shuts off.


When it flashes blue, are the flashes bright blue lines going across the screen with the picture in the background, if so, It sounds like the Blue tube or blue driver circuit is breaking down after a short period of time. If this is the case, the uPC that controls the set is detecting a large current drain on and is shutting the set off for protection, An engineers expert eye is required I`m afraid. Ian.

Toshiba rear projection has a very fragmented picture


By fragmented, do you mean pixelated?? If so, it may be worth trying different inputs to make sure that it`s the set and not the external equipment that is producing pixelated pictures, The primary fault that you may have could be due to the age of the set. Most CRT/TUBE TV sets start taking longer and longer to come on as they get older because the uPC (Computer) performs various checks on the set and one of these checks involves beam current. Basically, if one or all tubes were getting soft or poor due to age, the uPC would mute the video signal until such times that the tubes had warmed up sufficiently to provide a good picture. Basically, if this is the case, then it`s getting tired and if the delay gets to a point where it becomes unacceptable, then a replacement set is the only option. I hope this is helpful to you, Ian

Sound but no picture


You popped the plasma HV generator. Do you use a UPC all the time, if not then power line surges or brownouts can cause this type of problem. Needs Pro shop repair, expect around 450.00. PS: buy a upc for around 10 minutes run time $80.00 ??

Please rate!

Toshiba tv


Some common causes are:

A component is failing and it is thermo sensitive. As it warms up it starts to work in spec, and thus the set can start up. Most of the time this type of component can be in the scan amplifiers or in the power supply.

The CRT is going weak. When its emission level is below a specific value according to the design of the set, the uPC sends a command to not allow the high voltage to start up, or it is not allowing the the electron-guns to be biased on. As the heater in the CRT warms up, the electron-gun becomes in to proper spec, and thus the uPC allows operation.

Eventualy the set will no longer start up, or what ever is failing will fail completely.

You can take the set in for a service estimate, but personaly I would be shopping for a new set.
