Secondary but, check for a bad fan first as this is usually caused by an overheat problem

It is in secondary circuit which is also known as the high voltage circuit. Here very high voltage is created to enable the display unit to function properly.
Either some capacitor or IC, whichever is damaged. If you are familiar with repairing electric goods, then try to find out the exactly what is the reading and then check the values of components, like diode, transistor, etc needs to be pe[laced. If still under warranty, make full use of it. Else get the address of their authorized service center & get it repaired from them.

IMP: if the probleam leads to changing the display tube, it will be cost effective in buying a new TV...............sodeep

No 3.3 volts at blon


You need a new main board or a service of the existing one.

For 32'' models probably a replacement will be easier.

Turn the console on, displays the xbox screen then screen goes off and a red light starts flashing on console, says system error


is this a single red light? if so, it is a E code error. if there are 2, it is a overheating problem. if its 3, it is a general system error which could be a number of things which you need to figure out the secondary error code to narrow down the problem.
to find the secondary error code:
1. after the red lights start flashing, hold down the "controller sync" button.
2. push the "eject" button 4 times and count the amount of red lights that flash. the red lights will begin to flash rapidly. secondary error codes are only 4 numbers. 1 light = 1, 2 lights = 2, 3 lights = 3 and 4 lights = 4.
after you get the code go to this website, and on the right hand side of the screen under "Xbox Repair Guide" select your PRIMARY error code (1,2,3 or 4 slow flashing red lights). then it will ask you to enter your SECONDARY error code, which is the one you discovered in the steps above.
this will give you a very narrowed down idea of what is wrong with your console, and will give us "questions answerers" a better idea on how to help ya out!

My display keeps shutting off five minutes after starting to watch TV- the sound continues, but the screen is black and the red warning light flashes


Hi,

Please check the sequence in which your warning light flashes.

I will tell you what might be the problem according to the fashing of warning light,
If,

Flashing repeatedly --- Improper voltage supply
Flashing once --- Malfunctioning of fan
Flashing twice ---excessive temperature
Flashing 3 time or more--other problem

When flashing occurs please remove the power cord from receptacle and inform your dealer about the flashing sequence.

Thanx

Red light flashing...no picture. TV not turning


Probably a failed main power supply. There are at least two supplies; one that keeps the remote function alive continuously and the second that is turned on when the set is ordered to operate. The smaller supply is a low voltage circuit and that is providing your error indication.

Flashing red light no screen fujitsu plasma


This is a common complaint with Fujitsu plasma displays with a few years age. It is most likely caused by the Main Power pcb.

See Fujitsu Service Bulletin on this problem. -see link below
http://tomtom2k5.free.fr/fujitsu/PDP-0035-06.pdf

A competent service technician should be able to implement the service bulletin.
