    Fuzzy picture on my Toshiba until it warms up. Then it gets clearer. It has been doing this for a few months. Over time the fuzziness is getting worse.

Good Day, pieps57;

Corrective Action: Remove the MVUP13 Hyper Module from the TV chassis, remove the top shield and replace the 10uf, 16v capacitors using Part Number 24619040. It’s recommended that all of the capacitors identified be replaced (Note: These capacitors are low impedance surface mounted aluminum electrolytic capacitors. Care should be taken to avoid damaging the PCB while replacing these capacitors.) CAPS: cx178, cx221, cx230, cx241, cx250, cx261, cx270, cx541, cx670 & c514, c5030.
Good Luck, Big Irish.

The convergence going bad again on my Hitachi 51swx20b


Sounds like loose solder on the chips. Either that or they are failing. You can save money next time by doing it yourself with a kit from www.TvRepairKits.com

When the screen has a light picture you see pink color bloches all over the screen, when the picture is darker it's not that bad. It all started a few months ago with different colored spots on the screen.


Howdy,
The problem is with the EEPROM in the TV that needs to be reprogrammed. But you need to have the proper Correction Tool (LSUQ0100).
I don't think it's available to the public. Call a Service Company, but make sure they have the “Correction Tool”.


Thanks for using FIXYA, big IRISH.

For one thing you have a vertical problem and since it got that way gradually you can bet that there is a bad capacitor in the vert. circuit(pump-up cap) as far as the price goes it depends on your local servicemen, i`m in canada and that sort of problem fixed at home would run around a 100.00$. good luck

Big black box on screen


It has something to do with the closed captioning. He must have hit the closed caption button on your remote. You need to either turn the closed caption off or make another selection under closed captioning like cc1 cc2. Just keep making selections until the box goes away.

Shaky Picture only during Advertisement or... Mitsubishi SC 27403


If you have cable then put the cable wire directly in the TV, bypassing the cable box. If the pix is Ok it proves that the problem is the cable box. If the problem is still there then it proves the the TV needs parts inside.

No picture, only sound


The set has a shorted vertical output IC, probably a TA8427k. The capacitors around the heat sink of this IC dry out and cause the IC to run hot. The correct repair is to replace the vertical output and the electrolytic capacitors near it. Also use 105 centig instead of the original 85 centigrade. The is some time a pico fuse or current limittng resistor which must also be replaced. This a common problem with Toshiba and is not a bad picture tube. The usual cost of this repair is around $120-150 depending on the integrity of the technician. Scrivitron

Very wavy picture- gets worse when show has fast-cuts


First thing Do not beleive peeps about a bad card. Modules are not used in TV sets any more unles your talking about a complete board change out for a Zenith TV set. Toshiba sets do not have a card or board changeout!.. These peeps are crooks! A Toshiba set is repaired to componet level. It sounds like you may have a convergence problem or a problem inj the power supply involving the filter or couping capacitors. Seek out a pro whos an authorized servicer for Toshiba.
