Obtaining Service
For service advice, warranty exchange, warranty repair, or out-of-warranty repair:
1 Call Grass Valley Customer Support at the telephone number given under
page 231. Our Customer Service Personnel will help you resolve any service issues.
2 If you need an exchange or repair,
Grass Valley
will assign you a Return Material Authorization
(RMA) number. Do not return equipment without first receiving an RMA number.
Grass
Valley
uses the RMA to track receipt of the equipment and to record repair or replacement
information.
3 For out-of-warranty equipment, the
Grass Valley
Technical Support engineer estimates the
cost of repair when you call and requests a purchase order payable to
Grass Valley
.
4 If a repair or exchange is required, package the assembly in an antistatic bag and place it in a
shipping box with plenty of padding to prevent damage.
5 Address the package using the Shipping Address listed in this manual under
page 231, and ship the equipment to Grass Valley at your company’s expense.
6 When repair or replacement of in-warranty equipment is complete, Grass Valley return ships
the items at its own expense. For out-of-warranty equipment, Grass Valley charges a ship-
ping and handling fee. The standard shipping method is second day.
7 For out-of-warranty service,
Grass Valley
will send your company an invoice following the
repair or replacement.
Intermittent signal on one or two
outputs.
Check input and output cable continuity and cable terminations.
Swap each card in the signal path with another card to see if the
problem moves with the card. If so, replace the card.
If all cables, terminations, and cards check out OK, call Technical Sup-
port.
Intermittent or missing signals on
all outputs.
Possible low voltage on PS8100 or PS8300 power supply module.
Check power test points on the module. Voltages at power supply
test points may be slightly high in lightly loaded systems. Replace the
power supply module if any test points indicate low voltage.
NOTE: Video can pass through with no control cards installed, but the
