You may have three bad capacitors of the same values (35 volts at 1000Mfs). These are in your power supply. Locations are as follows:C965, C966, and C964.Also replace C975 which is a 35 volt at 220 Mf and 972 which is a 16 volt at 1000Mf. Be sure to use the 105 degree caps (high Temperature) in this unit. Hope this will help you in a fix. Thanks for asking and show all hands of support!
Replace capacitors CX2105 (35 volts 220 Mf), CX2110(35 volts 100Mf), C2104 (50 volts 1 Mf), resolder resistors RX2115, RX2116,R2118,R2119. You will need to also resolder the vertical IC. I think this IC location is IC 2200, its been sometime since I repaired this one.Do not short the pins together with excess solder. The values on the cap may not be exact. Please use the cap value that is removed (remove and replace one at a time). The locations will be correct! This will remove the horizontal lines or bars across the TV screen. You may as well replace capacitors in the horizontal deflection area. By now you have bad caps there. The locations and values are, CX3218 (160 volts 2.2Mf), CX3205 (16 volts at 100 Mf) CX3413 (50 volts 22 Mf) and CX3416 (25 volts 100Mf). Thanks for asking and show all hands of support.
If this a standard TV, you have several bad capacitors near the the vertical IC. The vertical IC will also need resoldered. Please do not short the pins with excess solder. The bad caps will be near the vertical IC. They always seem to put extremely small capacitors that are short lived in this unit. You will be concerned about electrolytic caps here. They look like miniature cans with two legs. You will need an ESR meter to locate and replace the caps. You those of the same voltage and Mfs. Find the 50 volt 1Mfs caps as they are bad. There will be a 25 or 35 volt cap at 100Mf that is bad. And there may be a 50 volt47 Mf too. Once again search with the ESR meter, you will find the caps. And inspect and resolder the rest of the board as necessary. Thanks for asking and show a few hands of support!
I believe the TV may be at fault here. This aging TV has a vertical problem, The horizontal bans you describe are common on an aging Zenith TV. You need to find an electronic enthusiast to correct this. Tell them to resolder the vertical IC and replace those capacitors that are near and next to the vertical IC. And have them replace the capacitors in the power supply. They will include a 25 volt 100 MF cap and a 35 volt 22 Mf cap. These are located very near the STR 5041 regulator on a large heat sink. Have them replace the high voltage deflection cap that is about 200 volts at 1 Mf, near the flyback transformer. And on the other end of the board near two heat sinks (one of these is the vertical IC heat sink) there is a 25 volt 220 Mf cap that is dead by now. resolder any and all bad grounds. Please save this TV and give it the longevity it deserves. Thanks for asking and show a few hands of support.
You may have one of two problems. A vertical one in which you may have horizontal lines across the top of the screen. Or one bright centered horizontal line. The fix here is to resolder the vertical IC and replace the capacitors near and next to the vertical IC. The second problem would be the dead set. In this case , the power supply will need reworked. You will need the following components. Replace the powerline regulator STR53041, the regulator N4923 and capacitors of these values, 25 volt at 100 MF and a 35 volt 22 Mf. these components are near and next to the regulator STR 53041. Now,next to or in front of the flyback transformer there is a small cap at high voltage...I believe this one may be a 200 volt at 1 or 2.2 Mf. replace this, and the other capacitor near two heat sinks on the edge of the board in front of the vertical IC is a 25 volt 220 Mf cap that is also dead. It has been a very longtime since I have repaired this one. But the information, will get your TV up and running again! Find an electronic hobbiest or a TV tech to repair this for you. This info will help you get a reasonable repair bill. Thanks for asking and show a few hands of support.
You have an aging TV and aging capacitors. There may be some bad grounds on the solder side of the main board. You need to first inspect the solder side of the board for bad solder connections. And find an ESR meter. (Capacitor Checker) No doubt you will find some weak capacitors. I would look for those almost anywhere on this TV. This TV is small and you should be able to test each and every electrolytic capacitor. The electrolytics are the caps that look like small cans with two legs. They are rated in Mfs. For example 35 volts @ 100 MF, 16 volts @47 Mf, 25 volts @ 4.7 MF, etc. Test all of them and replace as necessary. Good Luck and thanks for asking. Show a few hands of support.
You have bad capacitors in this unit. Replace capacitor (location) 2074 which is a 25 volt 2200Mf at 105 degrees. Change capacitor (location) 2081 which is a 35 volt 1200 Mf at 105 degrees. Change capacitor (location) 2066 which is a 16 volt 10Mf at 105 degrees. And to complete final repairs change out surface mount capacitors (locations) 2H08 and 2H09. The part numbers for these two identical surface mount caps is..223886975478. And one should consider changing the color crystal, also a surface mount. The number for this crystal is 823827736071. If unable to do this yourself, find a TV tech and show them this repair instruction. Good luck and show a few hands of support.
Senor....You have 2 bad capacitors on the deflection board..They are 160 volts 1 mf and you may have to check the the large Horizontal cap , I think it is 25 volt or 35 volt 1000mf cap. Good Luck PS Look for 250volt 4.7 cap is bad too! DE NADA!
