Vestel 11ak19 chassis blank raster when first anode turned up, no osd defective

ic901, rgb drive ic, but still no change. (there was no rgb inputs from jungle ic)
had to replace ic401 jungle chip tda8843 as well.
Vestel 11ak19 chassis dead set. Only the led is on, 140v rail stays low at only
13v defective ic901
Vestel 11ak20s chassis stuck on standby - red led, no functions thereafter
check the data on the 4meg crystal (x501). If the crystal has g.w. 4000 stamped on
it in big black bold writing i find it almost certainly this type of crystal. Worth
checking though
Vestel 15tft lcd tv unit is dead. Unit will not turn on. Checking the stand by
power supply found the switch mode power supply is not running. Voltage at
regulator ic is zero volts. However the half wave rectifier diode has 80 volts on
the cathode.1/2 watt resistor is open.
Vestel 15tft lcd tv distorted sound audio amplifier is defective.
Vestel 15tft lcd tv unit is a dead set tech needs to check the b+ on the
emitter of the horizontal output. Tech will need to check the areas around hor.
Drivers. It was found the voltage was normal but was at 106 vdc. But further visual
inspection on the driver found ring fractures in the solder connections in this
circuit... While the voltages were being measured the set began to operate
correctly.
Vestel 15tft lcd tv field collapse & no sound dry joints regulator ic,
re solder pins solve the problem
Vestel 17mb18 power is ok & the power led is light normal. But there is no any
picture and sound. It is stuck in standby. The power led is light normal (red), but
the on timer led (orange) is blinking up to the tv is off. What can be the fault?
Could you check if there is any voltage e.g. On the collector of the high voltage
transistor? A blinking power led is usually indicating a problem on the secondary
side of the power supply! So try to obtain a diagram and measure these voltages.
Vestel 20 inch tft tv tucked in standby mode (red led on). Is imposible to
turn it on from the front panel nor from the remote, all the power supply voltages
are ok. You must meter output lines of power supply unit and check that their
values being true (as standby voltages) and check the rear of board for any cold
solder and crack of board or solder.
