Someone offered me a jvc hdtv av-56wp74,and one person said just the bulb in the lamp has to be replaced;then when called jvc they said i had to by colored tubes for 300.00 each,,,,who do i believe

The tubes rarely fail in this model so it may be a convergence issue instead. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed.

Here is an example video

Hi Dave

Thanks for using FixYa. If the issue is with the failed convergence (STK) ICs which needs to be replaced then, it’s not a difficult job if you want to do this yourself, you should require some basic knowledge about soldering-resoldering components. To start with you’ll have to open the back of the unit and then replace the ICs(STK ICs) which are located behind the black/gray heat sink and also check theresistors as if they are short the ICs might blow again after sometime. Please check this picture:
And yes you are right there are repair kits available which includes repair instructions with the parts, if you want to do it yourself, you can buy and repair it yourself. Please do rate the solution if the issue is resolved or post a comment for further assistance.

Convergence problem


Did you lock the adjustment into the TV's memory? This step is the most often missed. Please follow the directions on the Users manual or on the service manual on how to set your memory to hold the configuration.

Find the menu item on setting the convergence adjustment into memory (the menu should have an informational screen on this topic)

I hope this helps

Thank you,

You have an convergence problem, There are 2 IC's that go bad and a few resisters that can change value. If you flip the board with the Chips inspect the pins for cold solder joints. The IC's can be purchased from matelectronics
