Found a Vizio VO42L By the dumpster and want to try and repair it. I plug it in and the orange logo lights up, press power and it turns on and the logo lights up white but picture flickers with horion


Sounds like it might be a solder joint. use the meter and check the ohms on each side of the solder joints on the board where the serial cables connect to the boards. it would be a good idea to check as many joints as you have time to. If it is a LED TV check Led control board for bad joints. if it uses Flourocarbon tubes check the transisters on each lighting control board. you may only have one board working causing partial back lighting.

Hi my name is jeremy snow and i have recently had problems with my sony trinitron xbr 1997. lately the picture like scrunches up into the top of the screen and the tv just goes black and now like sometimes...


This is typical with many sets when it goes old as there is a high possibility that the components over a period of heating and cooling , tend to bring on a problem of dry soldering. So my advice is to check the set for some loose joints that have played on to give you these erratic shut downs.

Remove main plug, the covers - with caution of high voltage, check for dry joints, use a good soldering iron to solder all suspected points. Please find below a links for tips on poor start ups.

It is possible you need to check the soldering at the deflection circuits/audio sections as the picture/sound comes back due loose joints which contacts when the circuit is lifted. Solder all the suspected joints with a good light to assist and make sure there are not solder bridges.

Str-de685 WHEN I POWERED I HEARD A CLICK BUT EVERYTHING OFF NO LIGHT.I CHECK BOTH FUSES AND ARE OK.


There is a relay on the power supply circuit board that might be faulty or has bad solder connections. If this relay does not work, power is not applied and everything is "dead". I had to re-solder the speaker relays on my STR-DE675 because they had cracked solder joints which made them work intermittently. It's possible that the power relay is what is causing your problems. If it has bad solder joints it might click, but power might not be able to pass trough the joints.

Does it still click when you turn it on or did it only do this once?

The A/c does not work in the rear.I have a 1996 nissan quest


you have a bad solder joint in your heater control head. If you can solder, you can fix it. I will fix it for $25 and send you a control head. Then you send yours back to me.

Here's our Villager/Quest web site.

You have to remove 4 plastic screws on console bottom. Then remove 2 screws at bottom of center trim panel. Then remove ash tray and 2 screws just above tray opening. Then 2 screws at top of center trim panel. Then pull off center trim panel. It has 2 spring clips in center.
Then remove 4 screws holding control head in.
Remove all electrical connectors.
remove thin plastic cover on bottom of unit. 2 plastic clips hold it on.
remove circuit board, and look on back side for crack around solder joint that is circled in red on picture. Or the joint next to it.
resolder the cracked joint. Don't heat the joint too much. Just enough to get solder to drop on to it.

Sounds like a bad solder joint in the power supply or if your audio stays when you lose the video its probably in the deflection circuit either vertical or horizontal. Check the yoke connections.pins for cracked solder as well as the vertical and horizontal outputs also around the flyback.

I would check for Bad solder joints around the flyback, and the verticle and horizontal yoke plugs for starters. Lower your volume and listen if you hear the high voltage come back up when your video comes back up. Let me know what you discover when you check the solder joints.

Ps2 slim's red light wont turn on (wont run games too)


I have the same problem. At first if I wiggled the powere supply cord, and pulled it in one direction, it worked. After a while it wouldn't turn on at all. I ordered another supply cord, but no luck. I opened up the PS2 to see if I could see anything. The male terminal which the power supply plugs into, has three solder joints on the bottom of the terminal. Mine had the main solder joint broke loose. I am going to try resoldering it back on. I will post again if it works. If not will probably just buy another one.
