Picture flipping Found a place on back for vert/hgt, but it is set in. Have tried inserting a screwdriver and turning, but no luck in stopping picture flipping.

    model is P4572JBA; other no. on set is 70527070. The picture got worse and worse, so I called a recommended technician. He came Mon. night and took away the innards. Seemed to know what the trouble was, and said it will be $300 plus labor to fix. Thanks for your concern. jrider.

The P52940 uses the 195 series chassis. The vert/hgt control is for vertical height. It adjusts the size of the picture from top to bottom. If your picture is flipping, it most likely means that something is wrong in the vertical circuits. I have seen fluid leak out of one of the CRTs and drip down on the vertical output IC, causeing the picture to go crazy vertically. The set should be serviced by a qualified tech experienced in the RCA 195 chassis.

    Hey jrider, I just thought of something. The RCA P52940 uses the PTK195 series chassis, as I stated before. The 195 series chassis does NOT have a vert. hgt. control! The vertical height is adjusted in the service menu. The last common chassis that had a vert. hgt. control was the 169 series. What is the exact model or chassis number of your set?

Sl 1210 mk2 problem spin on 33 rpm

Ok it could be the following of which is a very detailed way to go about fixing it so here we go:
1. Make sure your deck is set to 33rpm & that the pitch fader is at the greenlight or dead center spot. Remove the platter & plastic under covering that bares 5 phillips head screws. ee6d0e64-5572-4814-bdd5-3c288a65f86d.jpg 981b4425-f1bb-44db-8009-96c4f6f7045a.jpg
2. This is what it looks like without the platter & plastic cover.
3. Next flip your turntable over onto a big fluffy pillow to protect your tonearm mainly.
4. Remove the feet & all the screws from the bottom rubber cover. After that simply pull up the rubber cover easy & it may be a little tight in there so just do it nice & easy until it has been separated and completely removed out of the way.
5. Now on the underside of your pitch fader you'll see the board & locate the hole thats in that board & use a phillips screwdriver to turn it to the left all the way until it stops. db1b13b1-7724-4ad3-b6fb-849e4b202cf0.jpg
6. Now flip it over and turn it on, make sure its set to 33rpm & the pitch fader is st to "0" or where the greenlight turns on.
7. Then move the pitch fader in the "+" or positive direction or slide it towards you slowly a couple of increments say until you get to the "+2" the Big Red Dot moves & then comes to a stop again like it was before you moved the pitch fader when you stop on "+2". When that happens leave the pitch fader there turn off the deck, remove the platter and then unplug the pitch fader from its internal connection. a6fb6645-36a8-4b1e-b91c-c72b15b430dc.jpg
8. After its unplugged flipp it bck over again& now you need to bust out your Multimeter & set it to the 20k mark. 87b1f47f-20ee-40f6-b803-9f7559643700.jpg
9. After that then take your 2 contact points and place them on these to solder joints on the pitch fader board to get your first reading. e11add40-cf29-46a9-8030-8ef186bb2662.jpg 6c759cec-641c-4d93-bf6d-5c3702914fd6.jpg
10. Again dont go by what reading I have in the picture but instead whatever reading your mutlimeter gives you & write that number down & now you have to get the 2nd reading.
11. First you must reach underneath & now you can slide the pitch fader back into the "0" position or in the middle again & then repeat the same process you did when you got the first reading by placing your contacts again back on the two solder points and take a 2nd reading.
12. Now while you hold the black/red contacts on the solder points, you take your screwdriver & place it back into that hole from earlier & slowly turn it to the right until you see the reading on the multimeter screen matching whatever the number was that you got on your 1st reading. When they match stop & flip over your turntable & make sure you re-connect that plug for your pitch fader.
13. Now go ahead and put the rubber bottom cover back on with all those screws but leave the top internal plastic cover off still, of course you can put the platter back on but leave that plastic part underneath it off. TO BE CONTINUED...

Top of screen disappeared...cant see score of game

The Height adjustment is off... look in the back of the TV set, it has some knobs in the back, one should be vert.lin for Vertical Linearity adjustment, and there is another call Vert.Hgt. for Vertical Height adjustment. try adjusting the Vertical Height first with someone watching in the front of the big TV to see if the top comes back into view, you might have to adjust the knob very slowly one way then the other way, to make this adjustment. If it doesnot adjust take it to a TV shop to get it repaired.
Good Luck.

How to remove broken screen and replace with a new one on nokia 6350-1b

at first remove all screw from your ph, then you will see a clip beside of lcd. you unlock that one and put there new one

The whole blade set has come off and we have no manual to put back together

There is a small gun-metal colored bar at the very rear, just below the back of the blade when it is only the clipper. It pushes inward, in the direction of the blade. Push it firmly in and pull up on the teeth of the blade. It should pop upward. You can then remove the blade from the tongue that it sits upon. When you want to put it back, slide the blade back on the tongue, then, WITH THE MOTOR TURNED ON, push the blade down to its seated position. It will click into place.
If you have taken the blade off and the tongue has for some reason flipped back against the head, slide a screwdriver blade behind it and flip it back out so you can slide the blade back on it.

Good luck


Samsung HLN617W Screen Moved Up

Yes, you can repair it yourself. All you need is solder, solder wick, a capacitor checker rated at more than 1000uf and a screw driver.First, remove rear cover and locate vert. circuit. Check all 100uf capacitors around vertical output. Unsoldering one leg to remove from circuit so as to get a good reading. Replace leaky ones with equal value. Another possible cause for that is the convergence board. If you have colored shadows around the screen there is a small board up above main p.c.b. Simply replace it. Another thing to try is to access svc. menu and write down value of vert. hgt. Then change it back and forth to see if it is adjustable. this may be an easy, or difficult fix. Good luck, Russmann.

Vertical Diffusion

completely resolder the virtical circuit, including the vert. ic. i have also at times found an open resistor near the flyback that provides b+ to the vert. ic. if you can find a pinout if the ic, find the b+ pin & trace it back to the fluyback. good luck.

No picture

If you know how to trouble shoot solid state electronics, you should not have a problem trouble shooting this set. it sounds like a bad solder connection But these sets are not made for a consumer to repair as they are all soldered into placxe and inside a TV set is not tyhe place for a peep to br if he doesent uinderstand thongs

Picture problems

you have a vert sweep colapse. Fisrt thing is to get a schematic diagram and find the vert. output Ic and the clamper diode. Measure the voltage on both sides. If its low then its apossibility that the Ic was drawing loads of current and blew out the b+ feed resistor. Look on the schematic and trace back the voltage line from the vert output ic back to the sweep power supply on the secondary of the flyback transformer. check the limiter resistor to the feed and if its open replace the cap right there the resistor as well as the vertical output Ic ALL AT ONCE!!! If you dont you will cause it to go out again in a short time. Good Luck.. If you post the vert part of the schematic I will be more then happy to assist you with this repair.
