My aunt's tv started malfunctioning while I was at her house. I have repaired several other tv's recently, so I'd like to try and fix it within the next 5 days while I'm here. I have read a few different solutions to the problem the tv is displaying.
The tv will either power on and work correctly, or it will power on with sound, but no picture and turn off after 4 seconds. The red standby light will flash 6 times and then repeat the code. After it's been unplugged for a while the tv repeats the process and either comes on or flashes 6 times.
What is the solution to power supply failure? Totally replacing it would be my last resort, but would resoldering the power supply help any? Someone else had mentioned ic8002 (on the DZ board) was the problem.
Let me know, Thank you
Replace IC6501 and IC8002 at same time, both have same number and located parallel on DZ board. Part number is as follows..
670581001 MCZ3001DB
Available in Part Store.
No problem.
Let me know if you need further info for this TV.
Both chips have protection circuit inside that becomes unstable and start giving unnecessary trouble by shutting down TV that sensed by system control chip to blink front LED.
Hope your TV is working fine.
Make sure that pins of ICs are soldered well and clean PCB area after soldering new ICs
Good job!

Hi,
The Standby/Power light of the TV blinks when there is any internal malfunction in the TV.
The self-diagnostic function of the projection TV will cause the STANDBY light to blink or flash when the television detects an issue. The number of times the STANDBY light flashes corresponds to a specific issue. As per the two examples below, some of the issues may be resolved without the need for service.
If the STANDBY light flashes three times in sequence, the lamp cover is not securely attached. Reattach the lamp cover to resolve this issue.
If the STANDBY light flashes four times in sequence, the TV may be overheating. To resolve this issue, ensure that the back of the TV is well ventilated.
If the flash sequence is not listed above or the light continues to flash, follow the steps below to perform a power reset:
Try the following steps to check if the issue can be resolved.
Turn off the television.
Unplug the television power cord from the electrical outlet.
Let the television remain without power for 60 seconds.
Plug the power cord back into the electrical outlet.
If the television is plugged into a power strip or surge protector, remove it from the power strip or surge protector and plug it directly into the wall outlet. If the issue is resolved, the problem is with the power strip or surge protector and not the television.
If the issue continues to occur, service may be required.
Thanks for using Fixya.

Awesome! Thank you very much for your reply welcomejee. I was really hoping a guru would chime in. I hope to someday become as comfortable suggesting solutions as you seem to be. I will let you know if that does it. Thanks again for your reply
Fixya welcomejee!
Is there an explanation as to why this happened? I'd just like to understand what it was I did to fix the problem. Thanks again.
Actually it did fine for an hour, then 10 minutes ago it turned itself off and on a few times and then stayed on for a minute. Then it turned off and back on one more time and we haven't seen anymore problems since.
