To do that the fixya experts will need to know the make and model number of the amp in question.

Can i have a full view of a MTX Thunder 81000D amplifier two resistor got burn beyond recognizance and i need to replace them

Not sure about getting a better view but I suspect that you have more problems than just replacing the resistors. Like what caused the resistors to burn?

Screen becomes full of lines and picture dissappear but sound noot affected

These lines are called vertical retrace lines. The fault is related to its video amplifier section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy.

How to fix cracked PCI board in a amplifier

If the PC board is a single layer board then you can remove the coating on the printed circuits either side on the crack and then solder a small piece of wire on the printed circuit tracks. This will bridge the printed circuits across the cracks.
If the PC board is a multi-layer board then it is impossible to repair and the PC board needs to be replaces if you can get one. It maybe cheaper to get a new amplifier.

View lifestyle keeps powering off

It is possible that the amplifier had encountered a fault with a higher current drain which had triggered it to a protection fault condition. The fault can be your output drivers- the MOSFETS/IC's fitted for both the channels, Use a meter after disconnecting to check for short in the drivers. Disconnect the positive and negative voltages to the output and see if the protect changes. Even a fault in the preamp stages that drives in high current into the output can shut the Amplifier. Sometimes this can be a noise like a HUM or HISS before the protect works. Faulty capacitors in these circuits also can cause similar issues and needs close observation.
You need to confirm and replace the specific stages or outputs. If not there can be issues in the mother board, maybe the protect circuit by itself is shutting off due to a faulty bias , maybe a leak in any voltage/current sensing circuit. Also disconnect the speakers and test, if the protect is off then check for short on the speakers.

Have you checked all circuit boards for good solder connections.
Also if the boards had been wet from anything, you might clean the boards and resolder all connections specially in the power supply and audio section.

Let me know.
