Pvq2510 horizontal line of death

When I turn on the tube, there is a horizontal lit line across the middle of the screen. I was told by a TV repair shop that there's likely a blown capacitor (probably one of two is the culprit). I'm trying to figure out which two capacitors I should be looking at replacing. I could take a picture of the inside of the TV and send it to whoever could definately point the two capacitors out to me.

90% of the time -replace lthe LA7837 vert Ic on heat sink at top of small standup pc board and 100 mfd 35 v cap which connects to the diode just below the vert Ic.(note the polarity of the cap)
( LA7838 is a better replacement for the LA7837

Re: pvq2510 horizontal line of death

Ok the TV repair shop was correct the problem is with out a schematic you won't know which one it is. Let me explain. Even if you send a picture that actually tells a technician nother but the location of two capacitors. What is needed is a part number c13, c67... you get the point and then these can be looked up in a schematic to determine where they are in the circuit. I would suggest getting a schematic and sending an electronic copy to whomever you want to help you with this problem. I would be glad to help you but as a technician of 25 years I can only say that having and providing a schematic would be of a greater help then a picture. Unless yo plan on taking a picture of the whole circuit board and sending the model number and make of your TV to a technician so that they can look at the picture compare it to a schematic that they have (if they have one) and using that determine which capacitor or capcitors have to be replaced. Thank you,

Samsung TSL2793HF - Slight Right Side Pincushion and Horz Line Bottom to Top Until the TV Warms up

Yes, this is rare but I have seen it before--not fixable if it is what I think it is----It is what is called a Dome effect---the shadow mask in the picture tube is actually contracting and or expanding depending on temperature---

Directly behind the phosphor coating (the stripes that you see on the screen) is a metal screen--the holes or perforations in it line up with the stripes on the phosphor screen.

Some masks either have a material or a defect causing the dome effect----Not likely to be anything else---a Pin amp problem will not usually act the way you describe but a shadow mask inside the picture tube will act exactly that way.

Yes,hits the back plastic cabinate see if the picture flicker back to normal.Know how to slders just find out were is cold solders.Resolders that will fix it.Don't flicker back ur Horizontal IC is dead.Must take it to shop for IC replacement.

Thin line horizontally across screen

First of all this set is a CRT based set and thus has what is called a Vertical IC. This is the component that either has failed or has bad connections to the PC board. This is a simple and inexpensive repair. If you are comfortable working inside he set and can solder, you can fix this yourself. First look for the vertical IC. Is will be a small flat IC attached to a heatsink and will be marked TAxxx or LAxxx. Try resoldering the pins first. If that failes to resolve the problem, replace the IC.

If you are not sure whether or not you have the correct IC, post the marking here and I will confirm.

No picture just a line across the middle of the screen

a horizontal line means the vert output is defect,a vertical line means the hor. output is defect.

Green line in middle of tv when switched on

Is there a picture with the green line going through the centre. If it`s just a green line with no picture, it sounds like the Frame (Vertical scan) Output IC has failed and possibly the safety feed resistor near the LOPTX. The reason why it`s a green line is to protect the tube from phosphor damage. The older TV`s would produce a VERY bright white line across the screen which could burn the phosphors withing the tube if left turned on in that condition. It`s not an expensive repair, but is it worth it with the price of Modern TV`s nowadays. If there is a picture with a green line, it may be due to phosphor damage, in which case, it`s a new CRT (tube). Ian

When turned on only gets a straight line of color in middle of screen

You lost your vertical sweep. most likely the vertical output IC or a power supply source is the problem.

Tv not showing a picture

Hello e26pitts,

If the line is horizontal then it could be a problem in your vertical deflection section, if the line is vertical then the problem is in your horizontal deflection section. Now for a little more detail.

If Horizontal line is present the vertical section of the yoke transformer is nit responding to current flowing through it due to being open, or the vertical coupling capacitor is open, or even the vertical drive transistor might be defective.

If Vertical line is present the horizontal section of the yoke transformer might be bad. Now this gets kind is easy in a way, because the yoke would be the sole cause of your problem here (maybe there is some circuitry doing some horizontal coupling check that to) because the horizontal section controls other functions that would also respond if this were a horizontal drive issue. In any event these problems should be checked by a qualified TV technician, I would suggest that you take the TV to a repair shop to have it worked on.

I hope this helps
Thank you,

Horizontal line on screen

The most common problem would be a bad solder joint on the vertical drive IC. It could also be a bad solder joint on the flyback transformer, as it supplies voltage to the vert. stages. If you disassemble the set, please be careful not to get shocked. Discharge the high voltage stages as a precaution.

Tv repair

You don't have to buy a new tv, it is a fairly simple problem, your vertical ic is blown, and it could be the powersupply to the vertical ic also. To verify, slightly increase the screen voltage, and a horizontal line will appear on the screen, if the voltages is okay, change the ic, but first try resoldering the ic pins. Good luck
