This is not a simple fix. You will need a new module to fix. I would wait for the warranty repair.
call them everyday; it usually gets them there faster.

I have a Sony FD Trinitron 27' Model # KV-27FV310. It is approx 8 years old. After turning it on and watching a full screen for a few minutes; all of a sudden, a line came across half the screen;


top half missing is in vertical circuit of set---if it is a 27 inch and this old consider retiring it and replacing----other option is consider having a shop repair it--a rough guess would be as high as 150 dollars parts and labor is possible for your problems.

You need to replace the convergence ICs or to do a convergence setup.

Not turning on


There is a part inside the TV that needs to be replaced. If the TV is under warranty, call the manufacturer and they will arrange to have your set repaired at little, or no cost to you.

If the TV is out of warranty, and you have the experience and you know what you're doing, you can fix the unit yourself. Otherwise, if you've never done anything like this type of repair before and you don't know where to start, I suggest speaking with an experienced TV repair-person.

If you take the TV to a repair shop for out of warranty repair, the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

Since some brands will pay for your repair even if you're out of warranty, you should contact the manufacturer for your full range of options.

Hi My sanyo dp 42828 picture just went black. No prior problems.


G'Day!

Unfortunately, what you're describing is a repair issue. You won't be able to address the problem with troubleshooting. There is a part inside the TV that needs to be replaced. If you're under warranty, this will cost you nothing. If you're not under warranty the cost will likely be a minimum of $200 parts and labor. However, be warned that the cost could be considerably higher.

I was watching my tv (sanyo) with cable hooked to it. The cable all of a sudden went out. I tried hooking up the dvd player and the tv is no longer recognizing the cable box or dvd player. I don't know...


sound like a tuner problem. there is a resistor that goes to the tuner that could of went bad 39,000 ohms i think which should have a orange white orang strips around it and a gold. anyway there is a problem with tuner. Sanyo was good about haveing a problem with tuners in there smaller sets. If you do not know anything about how to repair you probly shoud take to a shop but the total cost might be high and not worth it in the long run. think before you jump still water runs deep.

That set is probably not ready for the dump yet. The buzzing sound could be the power supply going into shutdown because of a shorted secondary supply, usually a shorted horizontal output. A good tech should be able to fix that at a reasonable price.

Sanyo DS31520 went dead


If still under warranty or if you have no electronic repair experience you should take the set back to the shop or to a repair person. Some of the solutions described below can be dangerous, TV's are very hazardous to service. Even when plugged out, TV's can store very high voltages. Squealing noise is from the power supply teling you that there is an overload condiction. The overload is shifting the operational frequency of the power supply into upper audio hearing range. Check the diodes and caps in the supply circuit and the active components in the deflection circuit. also resolder the LOPT, h-output, h-driver, and h-driver transformer. Good luck

Screen split with black bar through center, top of picture shows in bottom


It sounds as you desribe, the vertical output IC and or the b+ feed capacitor off the Hi voltage transformer feeding the vert. IC its required voltage. Not a really hard job to replace, but not for a handi person to do. This should be left to the professional, as there are no user serviceable parts inside this set and with the HI voltage and the safety issues its best to call somesone to assist you with this repair. Good Luck
