Streaks in the centre of tv right through gh


Hi Beluda

Modern Digital TV's are really just Digital Computers with a CPU & Memory & a Flat Screen digital monitor, which uses the internal computers video memory to display content.
Streaks therefor would indicate a bad ribbon cable from main pcb to flat screen video screen or a video memory problem.

Today's HD TV's are NOT like the TV's of the past (Analog) that could easily be tweaked & fiddled with to get better picture results. It is made with Solid State Digital computer components.
So.... with that in mind.
Do you have the technical ability to fix a computer's internal cpu board?

If so, Open it up and put on your anti static strap & lets go.

Disconnect The Power.
Switch off at the wall to retain an antistatic ground point.
If you have a 3 pin power outlet (ground pin)

Check internally for poor connections (cold solder) or loose ribbon cables & connectors?
Look for cockroach & insect bodies & droppings on the circuit boards. (Shorts)
Look for overheated or damaged components.

But.... the biggest & most likely problem is that the DC voltages are not stable. (Poor Filtering)
This is caused by Leaky or Bulging Electrolytic Capacitors.
They have internal chemicals that deteriorate over time. Especially by being too close to their max voltage rating (printed on side)

There are No Internal 25KV voltages to worry about on Digital Flatscreen's.
There is a shock hazard on AC side of Switchmode Board.
Electro Caps on AC Input side can hold 110 / 240v
Check the Switchmode internal power supply on DC Side for bad Electrolytic Type Capacitors.
The insulated Tin Cans on the PCB with a Negative stripe down one side
Bulging or leaky Electrolytic Caps cause many failures in modern digital TV's

If you are not a Tech Type....
Take it to a service tech & ask to check Electrolytic Caps.
Most Tech's these days will Just Do A Board Swap. Costing $$$
If you are a tech type and feel like exploring & possibly fixing the problem.

Good Luck

Vivitek D326MX DLP, does no power up right away.


Almost certainly a faulty switch mode power supply. Since these are both complicated and dangerous for the inexperienced to play with, the best advice will be to take it to a service centre for repair. It's almost certain to be either failing electrolytic capacitors, or a high value startup resistor, or both, in the smps :o)

Cross lines ontop of screen my G21 M1 tv.. pls tell me how to solve it


The vertical output section of your TV has the fault. Replace all the electrolytic capacitors there, including smoothing capacitor to supply line to IC. Check for any loose solder termianls too. The lines you are seing across the screen, on it tope side, about 2 inches might be due to this fault, and are technically called [vertical retrace lines].

Vertical hold on a hitachi 53 inch projection tv, does not work on a/v inputs picture is stops rolling on hd inputs. Please help..


Hell
The set needs proper attention to its vertical output section, and synchronising seperatror sections. You must have through knoledge in electronics and repairing circuit boards. If you have, replace all the electrolytic capacitors at its vertical output section.

On power up I hold the power button down, I can hear some sort of relay kick-on, sometimes a horizontal white line appears across the screen, then it kicks-off, and the red led blinks four times...


Hi,
White line across the screen indicates that tv got vertical deflection failure problem that may be due to vertical output chip failure. If that kind of problem occurred, tv select protection mode and red light starts blinking 4 times.
Please check vertical output chip in tv main board and replace it to solve tv issue. This job needs soldering work so local tv repair shop will help you.
Thanks.
