Need signal board

Tuner is definitely no good.

You will need to replace the STK ICs,they are Big Black ICs and will have Part Number on them STK392-570.
Mats Electronics has Parts 1-800-628-1118
If you are unable to Solder you can ship board for repair to PTS 1-800-844-7871

These are bad about bad capacitors in the power supply and main pcbs. Unless you are good with MAJOR chinese puzzles, leave this one to a pro.

not sure which part you need main board (where flyback lives) is part no. 930b903002, power board ( where convergence IC's live) is part number 930b904001, signal board ( where tuner lives) is part no. 930b905001-55. I checked with encompass.com they have all three in stock.

Mouser electronics

Give them a call and give the information. They will have a replacment.

This a deflection problem. Both 2-3 and 2-4 are deflection. Most likely a verticale problem. a tech will need to fix it.

Your model is the VZ8 that doesnt have the pip board it has an IC for control of the PIP. So your problem has to be in the video or deflection circuits You can get a service manual off this link that I am part owner of if you need one. We also help by giving free support to help with the diagnosis and locating parts. This is a free service when you purchase a manual and we email the manual within minutes of placing your order. Its listed as VS60707 and sells for 10.99 its the full factory service manual.
Heres the link if your interested.

If your going to do the repairs yourself you can probaly get by fairly cheap, but service techs usually run between 3 and 6 hundred for video problems sounds like a capacitor issue. If you need a service manual and unlimited support for your set go to this link. Its 10.99 for the manual the supports free. They will mail it unless you return to the site and request that they email it along with the instructions on how to obtain the chat support. I am one of their support Techs, Hope this helps.
