Hi,
Who can help me with this problem my JVC tv has a couple of days this problem (see picture)
I have a service manual, but this does not completely matches the TV it self, different FEATURE BOX PWB.
Ajusting the PARAB option in de service menu does'nt any thing. the potmeter inside the TV gives some effect on the image but not enough.

Perhaps it has a defective part?
Time to use that service manual to troubleshoot the set, rather than hope that adjusting some parameter in the service menu will correct your problem.  |

Come on fellas, maybe its a language problem:

RiddledTV.com provides this information for those that are qualified and trained to do TV repair work. Entering or making changes in service mode by untrained persons can cause significant and permanent damage to your television. If you are not qualified to service your television, please DO NOT ENTER these service menu codes.

If my car develops a miss in the engine I think I will just adjust the electronic engine controls.
Sir, Your set has a pincussion problem and will require component level repairs. I would suggest you take it to someone that has at least some knowledge of electronics.
